It depends upon your choice. If you can handle the pressure and study the syllabus with the same dedication that you studied for two years before, then you can take it. Moreover, you need to work very hard as you mentioned you have very less marks in Mains this year.
Also, you can take admissions in private universities, but if you have another chance to prove yourself, go for it.

Hello,
I hope you are doing well. You can check the list of colleges including NITs and IIITs that you can get according to your marks and rank. Use Shiksha JEE college predictor:

I would suggest you to directly consult the colleges for admissions through on-campus procedures (management quota is different) as getting a college through online counselling is not possible. Also, try for admissions into private universities who have their entrances too.
Best of luck.

You'll not get any IIIT. But you'll easily get an NIT of lower ranking with mining and similar non - technical branches.
Best of luck.

Your MHTCET marks will not help you to get admissions in Madhya Pradesh. The best colleges in Madhya Pradesh are GSITS, Jabalpur Engineering College, MITS Gwalior, GECU Ujjain, RGPV Bhopal. You'll only be able to get RGPV Bhopal and GECU Ujjain with your marks.

With general, you'll get NIT Pondicherry, Silchar or Manipur with mining and related such branches (non-technical).
Also, it's not worth getting into these, spending 4 years and a huge fee as well.
The best I can suggest is LMNIIT where you can easily get mechanical or civil easily.
Best of luck.

You need 110 marks at least and it depends on cut-off. No one can say about minimum marks. Yes, 110 score is enough for CSE in a good college.
