Colleges in Andhra Pradesh

You should opt for CLAT exams for your post graduations, because they do give eligibility relaxation for OBC and physically challenged candidates. Check the website for details. Best of luck for your future endeavors.

Yes, you will get the admission but you need to submit all the certificates first.

Don't waste your years if you don't have the potential to crack JEE Mains but if you have the potential to crack the same then you should, but at the time of campus drive be ready to answer some questions.

Engineering/Technical courses in correspondence mode are not allowed by UGC/AICTE at present. Even the honorable Supreme Court has banned engineering courses in correspondence mode. You can do your B.Tech from Institution of Engineers (INDIA) or through lateral entry scheme.
All the best.
