Can I challenge the official BIT MCA answer key if I find an error?

BIT combines your scores using this formula: (Written Score * 0.4) + (Interview Score * 0.6). You need at least 38 weighted marks in total to qualify.

You must score 40 out of 100 in online interview. If you score less than this, you won't get a seat even if your written score was perfect.

Yes. The interview determines 60% of your final rank, while the written exam only counts for 40%. Even a written test topper can get rejected if they don't perform well here.

You must score 35+ out of 100 in the written test to be eligible for the interview round. But since the seats are limited, you must aim for 60+.

There is no negative marking. You receive 1 point for each correct answer. Try to score all 100 questions within the 120-minute limit to maximise your score.
