Bar applicants often second guess themselves on MBE questions, and choose the wrong answer over the right answer they picked originally. It’s important to recognize this pattern and interrupt it.
Make note of how often you pick the right answer and then second-guess yourself and choose the wrong answer, and figure out whether this is a big problem for you.
If it is, make a pact with yourself that you will only change an answer if you can articulate a reason (in IRAC format) why you are changing it. This means that you can’t change an answer just because you think another answer choice looks prettier, or the question must not be as simple as it seems. You can only change an answer if you missed something, or forgot something, the first time.
Remember to trust yourself and trust the process.
