If I do not qualify the competitive exams like IIT,JEE then what will be the best second option?

You should always remember IIT is not the end of the road. Incase you fail to qualify in JEE Advanced, you do have other options like securing admission in a NIT or GFTI, provided you have performed satisfactorily in JEE Mains, ideally with a AIR above 50k.

If you have appeared for BITSAT Examination, and secured above 280/450 you have great chances in securing admission in either of the Pilani, Goa or Hyderabad Campuses.

Besides this there are excellent State Technical Institutes like Anna University Chennai, Jadavpur University, Delhi Technological University, JNTU Kakinada, BIT Sindri, COEP, VJTI Mumbai, HBTI Kanpur which are equally good. Some of these institutes have their own Entrance Examinations like JU and JNTU K while others like DTU and BIT Sindri use the JEE Mains Score for Admission Purposes. You must keep am eye on the Counselling and Entrance procedure of your Respective State's Top Technical Institutes.

You should also appear for COMEDK as some of the best Technical Institutes in State of Karnataka like RVCE, BMSCE, MSRIT Bangalore continue their respective admission processes on basis of the COMEDK Score. These institutes have good infrastructure,faculty and enjoy a great employer outlook being located near IT and Industrial Hubs of Bangalore.

VIT Vellore and MIT Manipal are two of the best private technical institutes with great placement opportunities and you should also consider them in your college plans after JEE.
