Low Precision Score in Gyankatta test is lethal

In a test with a negative marking system, a low precision score is lethal because it directly reduces your final score and rank. Precision is the ratio of correctly answered questions to the total number of questions you attempted. A low precision score indicates that a high percentage of your attempted questions were incorrect, which leads to significant mark deductions.

Negative marking is designed to penalize random guessing and reward accuracy. For example, in many exams, for every wrong answer, a fraction of the marks for a correct answer is deducted from your total score. This means that a single incorrect answer can not only negate the positive marks you earned from a correct answer but also pull down your total score below what you would have achieved by simply leaving a question blank.

• Low Precision: A low precision score means you attempted a lot of questions you weren’t confident about and got many of them wrong. This results in a heavy penalty from the negative marking, which can drastically lower your overall score.
• High Precision: A high precision score, even with fewer attempted questions, means you only answered questions you were sure about. This strategic approach minimizes mark deductions and often leads to a higher net score and better rank than attempting many questions with low accuracy.

Therefore, in a test with negative marking, accuracy (high precision) is far more important than the sheer number of questions attempted. It’s often better to skip a question if you’re not sure, as an unattempted question gives a score of zero, while a wrong answer results in a negative score.
