How to use this practice hub
- Start with the topic you feel weakest in — practice your weak spots first, not your strengths.
- Read every explanation, even on questions you got right. Some have a "trap" worth knowing.
- Aim for 18+ out of 25 on each topic before considering it solid.
- Use the navigation strip at the top of each quiz to jump between topics.
- On the real TestGorilla test, you cannot go back to change answers — practice committing to a choice.
- The Critical Thinking test has only 12 minutes total — practice pacing yourself on Topic 5.
