Hello Aspirant!

Looking at your percentile in JEE Mains(i.e 28.2 %) your rank will be in lakhs(>1.5 lakh range)you can opt for the top private engineering colleges like bits pilani, bits Hyderabad, srm university, vit Vellore, etc by giving their respective entrance tests .

You can rather opt for any local private engineering colleges for just achieving a btech degree.

Hope this helps you :)
