Engineering

It depends. Are you from Tamil Nadu? If yes, then it's enough to have a rank below 6000 or 7000 for a department of your choice. If you want a department of your choice (the popular ones i.e. , ECE CSE mech), around 3000 will be your last resort. But there's also an option to change your department after 1st year, basic requirement being not having any backlogs. Also, there'll be competition. So, GPA above 8 in 1st year helps.

Here, I am attaching a list of colleges in Tamil Nadu who accept JEE score. https://www.shiksha.com/b-tech/ranking/top-engineering-colleges-in-tamil-nadu-accepting-jee-main/44-2-123-0-6244.

Yes, you will be selected and fees is INR. 2.75 Lacs per year, but if you get good rank in EAMCET, you can have scholarship.

In terms of marks, it should be approximately 90 and in term of percentile 80.

Yes, it is possible to do BE Mechanical after your Diploma.

Maybe, yes you get seat in AEEE college must try it also other.

I don't think they support lateral entry, still if you want a definitive answer, contact Chandigarh JAC, since they are ones taking care of admissions in PEC and other colleges in Chandigarh.

You can get admission after your CLAT score. Prepare for entrance exams and your score will decide your college.

No, it is absolutely not possible. AICTE does not allow distance courses. I would suggest you not to take admission anywhere an admission of such type is available. Regards.

Hi Vinaya,
If you have not appeared for the gate exam, then you will get admission through management quota. In management quota fees will be high (normally two times) and you will not receive any scholarships from government.
Best of luck.
