As per the analysis of following answer keys:-

1. Shankar IAS

2. Vision IAS

3. Vajiram and Ravi


IAS Delhi Institute (IDI) has compared answer keys for UPSC CSE Prelims-2020. There is a total of 4 discrepancies found in their answers keys which can cause a difference of more than 8 marks in marks of any student. To minimize this error, we have given 4th answer key in which answers of these 4 questions are chosen by a majority of two institutes. 

Hence, instead of referring to multiple answer keys, we suggest candidates, to calculate your score by answer key of IAS Delhi Institue (IDI) which will give you the most accurate score.

Keep Calm and Think Positive
