There is a particular kind of frustration in a mock test: you knew enough to get a good score, but a handful of rushed guesses pulled it down. The answer is not automatically “attempt fewer questions”. It is to understand how you made those choices.
An unanswered question can feel unfinished. Under time pressure, selecting any option gives a brief sense of progress. Your score, however, depends on the marking rules and the quality of that choice, not on how complete the screen looks.
Check the rules for the test in front of you
Read the reward for a correct answer, the deduction for a wrong answer and the score for leaving a question blank. Do not assume every examination uses the same penalty. Some topic practice sets have no negative marking at all.
For a simple example, suppose a correct answer earns 2 marks and an incorrect answer loses 0.5. If your chance of being correct is p, the expected score is 2p minus 0.5 times (1 minus p). That becomes positive when p is greater than 20%.
This calculation explains the trade-off; it does not tell you your real probability of being right. With four equally likely choices, a random guess has a positive mathematical expectation under those particular rules, but an individual attempt can still lose marks. Different penalties change the calculation. Time spent guessing also has a cost if it takes you away from a question you can solve.
Separate three kinds of answers
During practice, note whether you knew the answer, eliminated choices using a clear reason, or selected an option without a basis. Do this privately on your review sheet if the test interface does not have those labels.
A correct guess is not proof that you understood the topic. Review it just as seriously as a wrong answer. Otherwise your score can hide a weakness that returns in the next test.
If you eliminate a choice, name the reason. “The sentence needs a singular verb” is evidence. “Option C looks unusual” is not. Reliable elimination comes from the question, a rule or a fact you can explain.
Decide before the final-minute rush
Use mocks to establish how you handle uncertain questions. You might answer the clear ones first, mark a few for review, and return with the remaining time. In a test with locked sectional timing, that review must happen before the section closes.
Avoid changing an answer merely because you have stared at it for too long. Change it when you notice a missed condition, a calculation error or a stronger reason for another option.
Review decisions as well as marks
After submission, inspect your uncertain answers as a group. How often did evidence-based elimination work? Did you spend too long on low-confidence items? Were late changes usually supported by a specific correction?
You do not need a complicated spreadsheet. A few lines after each mock are enough to spot patterns. Use the next attempt to change one habit, such as reading “except” twice or checking the percentage base.
A calmer test is not one where you feel certain about everything. It is one where you have a repeatable way to choose, skip and review. Practise that process in Mock Tests before relying on it under exam pressure.
