Hello,

Here is a good question as per your query first you should know that the kcet exam is not dependent only on your kcet marks and also its dependent on your 12th/2nd PUC marks, combining both the marks it will be normalized and your rank will be decided.

Coming to your first question that if you want to score the 75-80 marks you can score very easily by following your board exam lectures but, if you want to come under 75th - 80th rank its little difficult, not impossible if you score 98% in PCM in your 2nd PUC and 165-170 marks out of 180 in kcet you can get 75 - 80 rank.

About MSRIT cut off of CSE it was 2139 last year in 2020. It will not vary much this year so, if you can achieve rank below 2000 you can get admitted to MSRIT in CSE branch.

Hope you have no doubts in this answer.
