Last years' cut off was around 89 for general and it goes only higher every year. So I am afraid that your chances are very poor.

I am afraid that you have scored a bit lower percentile. Last year the cutoff for general category candidates was around 90. But you should not dwell too much on this. Learn from this and prepare in a better way for second attempt in April. Remember there is nothing impossible. Have positive thoughts and I am sure you will get 90+ percentile in April.

I am afraid with percentile just above 50, means almost 4.5Lstudents have better score than you. I would therefore like to advise you that based on answer keys, try to find out where you went wrong, prepare once again in better way your weak areas and appear strongly in April once again with better preparation with aim of scoring 90+ percentile.

I am afraid with this percentile you will most likely be outside the cutoff. It was almost 90 last year. However, do not loose hope. You have one more chance in April to improve your percentile. Start preparing earnestly right away and I am sure you will score more than 95 percentile for a shot at CS branch.
