Hey manisha, 

To get admission in Msc computer science (hons.), eligibility criteria is :

~Candidates with BCA or Bsc./Bsc. (hons) with minimum aggregate of 60%

~. Maths as a compulsory subject.

In few universities, there are entrance exams for admission in Msc. (hons).

As I can see that you have aggregate of 55%, therefore it would not be possible for you to get admitted in Msc. (hons).

Don't get disheartened. You have a bright future ahead. If you want counselling regarding which course you should go for, feel free to drop a comment below.

We would be glad to assist you.

All the best!
