Marking Scheme for IAS Exam

In Prelims, every question holds two marks; thus if an examinee answers a question correctly, they will be rewarded with two marks. For every wrong answer, UPSC deducts one-third of the question’s mark. For example, if an examinee attempts 79 questions out of which 64 questions are correct but 15 wrong, then his expected score would be (64×2 – 15×0.67), i.e., 128 – 10 = 118 marks.

Calculation of Score in IAS 2018 

Using this year’s IAS Answer Key, you can easily match the number of right and wrong answers. The exact score can be calculated with the help of UPSC Answer Key as shown below.
