Well, according to the information I have received from my friends enrolled in both the institutes, I would say that both of these institutes are not that good. 

• The teaching methodologies used are extremely bad, and the alumni network of both colleges is utterly awful.
• If you have a good academic record and are good at understanding concepts then do not consider these colleges.
• I believe that you should work on yourself and improve your skills and knowledge to become an engineer.
• You can opt for a drop year and prepare for the JEE Examinations of the following year.
• Study for a minimum of 3-4 months so that you can at least be eligible for admission at a decent institute, better than these two.

Ensure that you have the appropriate knowledge from the 10+2 education, before applying for admission at colleges. I hope that these suggestions would help you in creating better prospects for your career.
