How to use this sample
- Set a short timer and answer without notes.
- Mark any answer that was a guess, even if it turns out correct.
- Review the reason each wrong option is tempting.
- Convert the result into one content priority and one process priority.
Science sample
Biology: A mutation prevents proper spindle fiber attachment during mitosis. Which outcome is most directly expected? Review note: the tested idea is chromosome segregation, so the best answer would involve abnormal distribution of chromosomes to daughter cells.
General chemistry: If the volume of a gas doubles at constant temperature and moles, what happens to pressure? Review note: Boyle's law predicts an inverse relationship, so pressure is halved.
Organic chemistry: Which feature makes a carbocation more stable? Review note: alkyl substitution and resonance can stabilize positive charge by electron donation or delocalization.
PAT and reading sample
PAT: A cube-counting item asks how many cubes have exactly three exposed faces. Review note: corner cubes on the outside of a complete rectangular solid often have three exposed faces, but missing or hidden support cubes change the count.
Reading: A passage argues that a new dental material is promising but lacks long-term clinical data. Review note: the safest inference is limited to cautious promise, not proven superiority.
Quantitative reasoning sample
Question: A solution is diluted from 10 mL to 50 mL. If the original concentration was 2.0 M, what is the final concentration? Review note: use C1V1 = C2V2, so C2 = 0.4 M.
The review goal is not to memorize these items. It is to identify whether misses came from content, setup, visual tracking, evidence retrieval, or pacing.
