3-Week Final Prep for a Texas CBE — Day-by-Day Checklist

Texas CBE Team· July 05, 2026· 14 min read· 46 views

Key Facts

Texas has two CBE routes: TEC §28.023 acceleration passes at 80%; 19 TAC §74.24 credit with prior instruction passes at 70%.
Both routes must cover the full TEKS for the course being tested.
District testing windows and administration policies vary; the campus counselor is the authoritative source for local logistics.
A three-week final prep is designed to close a familiarity gap, not to learn a course from scratch. Students who have not seen the material should defer the test date.
Week -3 begins with an untimed baseline diagnostic mock; without a starting score, subsequent decisions have no basis.
Wrong-answer analysis distinguishes three miss types: content gap, process error, and time miss — each calls for different remediation.
Week -2 uses a strict learn → practice → analyze loop on the top two or three weakest TEKS categories, one at a time.
Week -1 runs one full-length mock daily, at the same time of day as the real exam, under real conditions (single monitor, permitted tools only, camera on if the real exam is proctored).
Test week reduces study volume. Sleep two nights before the exam has measurable next-day cognitive impact — Thursday sleep matters, not just Friday.
Test-day pacing is a three-pass strategy: quick pass to answer what you know, second pass on flagged items, third pass to check and fill every answer.

Most families walk into the last three weeks of Credit by Examination (CBE) prep with the right instinct — "we need a plan" — but no structure. The three-week window is short enough that a plan matters and long enough that a good one moves the needle.

This guide lays out what to do on which day. It applies to both legal routes for a Texas CBE:

Texas Education Code §28.023 (Acceleration) — no prior instruction required, passing threshold is 80%.
19 Texas Administrative Code §74.24 (Credit with prior instruction) — passing threshold is 70%.

The prep structure below is the same for both routes; the target score is what differs. Districts set their own testing windows and administration policies, so verify final logistics with your campus counselor before test week.

Five sequential phases across 21 days.

What "final prep" actually means

Three weeks is enough time to close a familiarity gap — the difference between "I studied this material" and "I can produce correct answers under exam conditions". It is not enough time to learn a course from scratch. If a student has completed the coursework (in a Texas classroom, at UT High School, at home, or through another approved provider), a well-designed three-week prep can shift their scoring band. If they have not seen the material at all, three weeks is not the right window; the honest answer there is to defer the test date.

The four skills that a three-week prep genuinely improves:

Recognition speed — turning "I know how to do this" into "I know how to do this in 45 seconds".
Time management — pacing across the full exam length (most Texas CBEs run about three hours).
Error pattern awareness — the same mistake tends to recur; making it visible is how it stops recurring.
Test-day steadiness — sleep, logistics, environment, and calm strategy under time pressure.

Week -3 — Diagnose and plan

The single highest-value activity of the entire three-week window happens on Day 1: an untimed baseline diagnostic. Do not skip it. Without a starting score, none of the subsequent decisions have a basis.

Day 1 (Monday, ~2 hours)

Sit down and complete a full-length mock exam at exam pace. Use a quiet room; put the phone in another room; use only the tools the actual test will allow (paper, pencil, calculator if permitted for the subject).
Do not correct anything mid-test. Do not look up answers. Reproduce test conditions as closely as possible.
Score the mock and record the number. This is your baseline.

Day 2 (Tuesday, ~2 hours)

Review every wrong answer. For each one, write two lines in a notebook: (a) the specific TEKS category or concept it tested, and (b) whether the miss was a content gap (didn't know the concept), a process error (knew the concept, executed wrong), or a time miss (didn't reach it).
Tally the miss counts by TEKS category. This produces a ranked list of weak categories — the map for the next two weeks.

Day 3–5 (Wednesday–Friday, ~90 minutes each)

Take the top two or three weakest TEKS categories and spend one focused session on each. The goal is not to master them yet — the goal is to identify whether the weakness is conceptual (needs re-teaching) or procedural (needs targeted drilling). This distinction changes what you do in Week -2.

Weekend (Saturday–Sunday, ~2 hours combined)

Write the Week -2 study plan. Decide which categories get how much time. Block the sessions on the calendar. Confirm the exam date and time with your district or provider.
Confirm what tools will be allowed on test day (calculator model, formula sheet, scratch paper). Calculator policies vary by subject and district; the campus counselor is the authoritative source.

Week -2 — Deep focus on weak categories

Week -2 is where score improvement actually happens. The structure: rotate through the weakest categories from Week -3, and inside each session, follow a strict learn → practice → analyze loop.

Daily structure (Monday–Friday, ~90 minutes each)

Learn (20 min) — Re-teach the concept from a textbook, a lesson, or a video. If the miss was procedural, skip to step 2.
Practice (45 min) — Do 15–20 targeted problems on that single category. Do not mix categories in this block.
Analyze (25 min) — Mark every wrong answer and every guessed correct answer. Both are learning signals. Write the miss type in the error notebook.

Rotate categories across the week so each of the weakest three gets at least two sessions. If the weakest category is very weak, give it three.

Weekend of Week -2 (mid-plan checkpoint)

Saturday: Sit a half-length timed mock (about 90 minutes for a 3-hour exam). Focus on time management — did you finish on pace? Score it and compare to the Week -3 baseline for the same categories.
Sunday: One shorter session (~45 minutes) on the single stubborn category that has not moved. Rest the rest of the day.

Realistic expectation: after Week -2, a diligent student typically sees the categories they focused on move from "consistently missing" to "consistently getting", with the remaining risk concentrating in categories they did not have time to touch. That is the correct outcome — you are trading breadth for depth in a limited window.

Week -1 — Full mocks under real conditions

Week -1 is a mock-exam cycle. The goal shifts from learning content to calibrating the whole exam performance: pacing, stamina, and stress response.

Monday–Friday (one full mock daily, ~3 hours + review)

Take a full-length mock at the same time of day the real exam is scheduled. If the real exam is at 9:00 a.m., the mock is at 9:00 a.m. Circadian pacing matters more than people expect.
Enforce real conditions: single monitor if the real exam is online-proctored, no phone, no music, exactly the permitted tools. If the actual exam uses Proctorio or a similar remote-proctoring service, replicate the camera-on, clear-desk, single-tab setup during the mock. First-time users routinely spend 10–15 minutes on setup on real test day; you do not want that surprise.
After the mock, use the same three-column analysis from Week -3: content gap, process error, or time miss. Add the day's misses to the error notebook.
Total daily time: about 3 hours for the mock, plus 45–60 minutes review. This is intense; it is designed to be intense for exactly five days.

Weekend (Saturday–Sunday, light)

Saturday: Light review of the error notebook, no new content. About 45 minutes total.
Sunday: Rest completely from study. Physical rest and sleep now compound into next week.

Score trajectory reading

If your mock scores are trending upward across Week -1, the plan is working; keep it. If they are flat, the misses are shifting between categories rather than accumulating in a stable way, which usually means the weekly focus categories are being displaced by different weak categories. In that case, spend Sunday reviewing the error notebook globally and identifying the newly-visible weak spots for test-week fine-tuning, rather than starting fresh new content.

Test week — fine-tune, rest, and confirm logistics

The temptation in test week is to double down on studying. Do not. The evidence and the experience both point the same way: study volume in test week matters far less than test-week logistics and the two nights of sleep before the exam.

Monday–Wednesday (~45 minutes daily)

Review the error notebook only. No new content. No new problem sets.
One "confidence pass" through the strongest categories — do five easy problems in each to reinforce that the skill is there when needed.

Thursday (~30 minutes, then stop)

Confirm every logistic in writing:
- Exam date, time, and location (or online-proctoring link).
- What identification is required (typically photo ID; verify with your district).
- What tools are allowed (calculator model, scratch paper, formula sheet if applicable).
- Arrival time (typically at least 15 minutes before start).
Set out clothes and materials the night before. This removes decisions from test morning.

Friday / test-eve

No studying. A short familiar activity (a walk, a hobby) is more useful than one more study block.
Sleep target: 7–9 hours. Sleep two nights before the exam has been shown in multiple studies to affect next-day cognitive performance more than the sleep immediately before, so the sleep target on Thursday matters too.

Test day — execute calmly

Morning

Wake at least two hours before the exam start. Give the brain time to actually turn on.
Eat something familiar. Test day is not the day to try a new breakfast.
Arrive early. For online-proctored exams, log in 15 minutes before the scheduled start to handle any technical setup.

What to bring (typical — verify with your district)

Photo identification.
Approved calculator (if the subject permits one).
Number 2 pencils and a good eraser for paper-based versions.
Water and a light snack if the testing environment allows.
For online-proctored exams: a clear desk (nothing on it except allowed items), a working webcam and microphone, and a stable internet connection.

During the exam — pacing strategy

First pass: Move through the exam once, answering the questions you know quickly. Flag any question that will take more than about 90 seconds and skip it.
Second pass: Come back to the flagged questions with the time you have left. If you spent 90 minutes on the first pass and there is 90 minutes remaining, you have time to think.
Third pass: Use the last few minutes to check answers on questions you were unsure about, then to make sure every answer bubble is filled — most Texas CBEs do not penalize guessing, so an unanswered question is a guaranteed missed point.

If you get stuck

Skip and return. The single most common time-management error is spending eight minutes on one hard problem and then not finishing the last three easier ones. The second most common is changing a correct answer to a wrong one on the second pass — only change an answer if you can articulate the specific reason.

After the exam

Score reporting timelines vary by provider — some districts return results within a few business days; others take longer. Ask before you leave the testing site how and when scores will be released.
If the score meets your route's threshold (80% for §28.023 acceleration, 70% for §74.24 credit recovery), the district processes the credit onto the transcript. Confirm with the campus counselor exactly how and when the credit appears.
If the score is below threshold, most districts allow a retake, but retake rules and cooldown periods vary. Verify with the counselor before scheduling the next attempt.

Bottom line

Three weeks is not a lot of time, but it is enough time for a student who has already completed the coursework. Diagnose in Week -3, focus in Week -2, calibrate in Week -1, and rest in test week. Do not compress it; do not skip Week -3's diagnostic; do not study on test-eve. The plan works because each week does exactly one job.

Frequently Asked Questions

Which route applies to my student — §28.023 or §74.24?

The acceleration route under TEC §28.023 is used when a student has not received prior classroom instruction in the course and wants to earn credit by demonstrating mastery. The credit-with-prior-instruction route under 19 TAC §74.24 is used when a student has already had instruction and needs to earn credit that was not previously awarded. The passing threshold is different (80% vs 70%), so the target score depends on which route the district applies. Ask the campus counselor which route the student is being scheduled under.

What if my student only has two weeks, not three?

Compress Week -3 into two days: one diagnostic mock on Day 1 and one review-and-plan day on Day 2. Then run Week -2 as written and Week -1 as written. The parts of the plan that cannot be shortened without giving up meaningful score improvement are the mock-exam cycle in Week -1 and the sleep-and-logistics discipline in test week.

What if my student's diagnostic score is well below 60%?

This is the signal to be honest about the timeline. Three weeks can lift a 65% to a passing score with disciplined work; three weeks cannot reliably lift a 45% to a passing score. If deferring the test is possible, defer. If it is not possible, focus Week -2 on the two categories that give the biggest score lift per hour studied (usually the most heavily weighted TEKS categories) rather than trying to cover everything.

Do I need a tutor?

No, the plan is designed to be self-directed for a motivated student. A tutor is helpful for two situations: (1) the student is stuck on a specific conceptual gap that self-study is not resolving, or (2) the student needs external accountability to stay on schedule. In both cases, a few targeted tutoring sessions during Week -2 are usually enough — a tutor for the full three weeks is not required for most students.

Are practice question banks worth paying for, or should I use free ones?

Free sample questions on subject pages are enough to begin Week -3's diagnostic and initial Week -2 sessions. The Week -1 full-mock cycle is where question volume matters most; running five mocks with the same fifty free questions loses signal fast. Paid banks earn their keep in Week -1, not Week -3.

Should I try to memorize formulas the night before?

Only if the formula sheet on test day will not include them. Cramming memorization the night before displaces sleep, which has a larger negative effect on next-day performance than the formula recall has positive effect. If the district provides a formula sheet, this concern disappears — confirm with the campus counselor.

My student is homeschooling — does this plan still apply?

Yes. Homeschool students typically test through providers like UT High School under the 19 TAC §74.24 route (70% pass), and the prep structure is identical. The one difference is that a homeschool parent is often also the person confirming logistics, so build the Thursday logistics-confirmation step into the calendar with extra care.
