How to Build a Personal Mistake Log System (The Most Underrated Tool in Your Preparation)
Why Most Aspirants Repeat the Same Mistakes
Every aspirant solves hundreds of questions, yet many remain stuck in the same score range. The problem is not lack of effort, it is lack of structured reflection.
You solve, check answers, and move on. But the mistake remains uncorrected.
Top performers don’t just solve questions—they track, analyse, and eliminate mistakes systematically.
A Personal Mistake Log System converts practice into progress and can improve your score by 15–30 marks without increasing study hours.
