One of the most important — and psychologically difficult — skills in Section A is knowing when to guess and move on. Many candidates waste valuable minutes wrestling with questions they are unlikely to answer correctly, at the cost of marks they could have earned elsewhere. This lesson explains the mathematics of guessing, the psychology behind reluctance to guess, and practical strategies for making quick, effective guesses.
The LNAT has no negative marking. This single fact changes everything about your guessing strategy.
Each multiple-choice question has either 4 or 5 answer options. If you guess randomly:
| Number of Options | Probability of Guessing Correctly | Expected Marks per Guess |
|---|---|---|
| 4 options | 25% | 0.25 |
| 5 options | 20% | 0.20 |
Now compare this to the expected value of leaving a question blank:
| Strategy | Expected Marks |
|---|---|
| Random guess (4 options) | 0.25 |
| Random guess (5 options) | 0.20 |
| Leaving it blank | 0.00 |
A random guess is always better than a blank. Always.
