What should you do if you get stuck on a question and cannot determine the correct answer?

Guess and move on
Do not move on until you figure out an answer, no matter how much time it takes
Move onto the next question and come back to it after you’ve finished the rest of the test
Look at your neighbor to see what they answered

The recommended approach would be to guess and move on. Dwelling on a single question for too long can waste precious time and hinder your performance on other parts of the test. Once you have finished answering the remaining questions, you can go back and revisit the difficult question if time permits. It is not advisable to look at your neighbor's answer as it may be incorrect, and it can constitute cheating if you are taking a test.
