CBSE 12th

You should go for biotech engineering. It's a great field with vast scope, even in foreign.

Getting a seat in these colleges is very easy. You just need to have 60% above marks in 12th and since you have an average JEE score, you can directly contact them for the admission in their office. They won't offer you CSE or IT. But you can go for other branches.

Please specify your stream of education, with which you have done your 12th.

You can get a government college but it also depends on the branch. Go for counselling process.

No college would submit your any of the original mark sheets. They would ask for the migration and TC certificates originals which you can easily get from the school or board by stating it to be missing or any other reasons. All the best for your preparation.

I will advise you to pursue science if you are good at it and understand it as it is all about understanding and not mugging up. I am advising you for science because it will help you to go to any field and if in future, you want to change your field or join join any other field, it will be easier as compared to other stream.

Many people go through this procedure. A lot of people cannot obtain the marks they wanted to in their HSC or realise its value once their result is out. But there is an option to rectify it. You can give improvisation exams next year and make your result better.
