To succeed in JEE Main, knowledge isn't enough; you also need speed. Many students lose marks because they run out of time, even if they know the answers. Learn how much time to spend on a question and when to move on through mock tests. This is the best way to balance speed and accuracy.
Analysis is Crucial
More important than taking the test is analyzing it. After the test, spend 2 to 3 hours reviewing the paper.
• Why did I make a mistake? (Conceptual error?)
• Was it a careless mistake?
• Did I run out of time?
Note these down. If you take about 25 full mock tests and analyze them properly, you'll see a big improvement in your score and confidence.
