What Is Total Marks Obtained

Total Marks Obtained is the final score a student gets after an exam. It is found by adding up points for correct answers and taking away points for wrong ones. This number helps students see how well they did on the test compared to what is needed to pass.

How Total Marks Obtained Is Calculated

Formula

To find the total marks, you first multiply the number of right answers by the points given for each one. This gives you the positive score. Then, you multiply the number of wrong answers by the negative marking value. This is the penalty. Finally, you take the penalty away from the positive score to get your final result.

Why Total Marks Obtained Matters

Knowing your total marks is helpful to guess if you might qualify for the next round. It gives you a clear idea of where you stand before the official scores are released.

Why Accuracy Is Important for Selection

Having high accuracy is often better than just answering many questions. If you guess too many answers, the negative marking can lower your score a lot. This tool shows you how many points you lose due to mistakes, helping you see if guessing was a good idea or not.

For CBT Stage 1

For the first stage of the Computer Based Test, the competition is usually high. You may need a high net score to move forward. This calculation helps you see if your score is close to the usual cut-off marks for this stage.

For CBT Stage 2

The second stage often has more questions and might be harder. The marking scheme might change slightly. Checking your estimated marks here helps you understand if you performed well enough for the harder level of this exam.

Total Marks Obtained vs Raw Score

Raw score is just the total number of correct answers. Total Marks Obtained is different because it includes negative marking for wrong answers. Looking only at the raw score can be misleading because it does not show the points lost for mistakes.
