Sir I am considering BIT Jaipur for persuing my career in engineering. how is that college is it apt. And then there is Banasthali and UPTU colleges like akg kiet or abes. which one should I with?

According to me you should drop one year and prepare once again so that you can get reputed college like IIT or NIT, pursuing bachelors from below avg rating college is not worth, you wont a nice job.
Rest is your decision.
