JEE Main

Hello Devashish,
Your score is not that good to get any college through JEE Mains JOSAA counselling.
So, better you can try for some other private colleges such as LNCT, Galgotias, Jaypee, Nirma, and MIT Pune according to your marks.
Best of luck.

Amity University, SRM University and BITS Pilani are some of the best colleges.

No, you should not take drop for CS in Techno India specially. If you are taking drop then you should take your chances for some much better colleges.

For this rank, it is very tough to get a government seat. You can try for NRI, quota in SRM, etc.

Through this rank of 215606 and 11944, you will not get any kind of IIT but you may get NITs and probably some of the low rank government colleges. So rather taking low government colleges, I would say that you should join private colleges in Noida, Ghaziabad, etc.

First and the foremost advice would be to learn all the basics only and only through NCERT. Now, you must have joined any coaching, so just solve the material and never go for the theory part. Follow your notes and have a short note or cheat sheet of each and every chapter. October to December should be devoted just to test series.
Take them very seriously.

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.

No, you have to go through the paper of COMEDK for getting admission in the top colleges in Bangalore. You don't need JEE Mains for the same. Bangalore is the best option for doing CSE through colleges like RVCE, MSRIT, etc.

However, as per your rank, you may not get allocated any seat in the first round but as the counseling process, you will get good branches at lower NITs.

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