Cramming right before the test feels productive but hides your real gaps. A full-length mock now diagnoses which TEKS categories you're weakest in — so you can focus your study only where it counts. Learning science is clear: retrieval practice and spaced study beat last-minute cramming. Starting earlier is the higher-scoring path.
