JEE Main

Your OBC NCL rank 7000 in JEE Mains puts you in a favorable position for admission in the following NITs: NIT Calicut, NIT Jamshedpur, NIT kurukshetra and NIT Silchar. Another good IIIT is IIIT Sri City, Chittoor which is on par with IIIT Nagpur. Your chances at NIT Jamshedpur are good.

The VTUEEE syllabus while similar, is considered slightly easier than the JEE Main. However both the exams follow the same CBSE/NCERT syllabus for PCM subjects. The JEE Mains question papers are a bit difficulty and are tuned on moderate to difficult level as comapred to VTUEEE.

With 3 Lacs CRL and 11k OBC-NCL rank, chances in JoSAA are low for top branches. But don't skip counseling. Try filling all NITs, IIITs, and even lower branches. Also check CSAB special rounds later. You might still get a seat if some colleges have vacant spots.
