Hello aspirant, you need under 5K rank for CSE branch in category 1 and under 20K rank for category 3 or 4. You have a very slim chance of getting CSE in category 5 for which you need to pay a very large fees around 5 Lakh per annum.

For 64799 rank in VITEEE  you should try to get admission in core branches in VIT Vellore or Chennai in category 2 or 3. You can get mechanical, civil and other core branches at VIT Vellore main branch as well as in VIT Chennai campus.

For category 2 the fees is around 2.32 Lakh per annum and for category 3 it is about 3.5 Lakh per annum. So if you are comfortable with the fees then you should try to get a seat in core branches in VIT or according to my opinion you should try to get CSE branch in other colleges that will require a much lesser fees.

Yes you can get a seat in VIT Vellore main campus but in core branches like mechanical or civil and not in CSE or ECE.

BEST OF LUCK FOR YOUR FU TURE!!
