From where can I get the question papers of previous year's JEE Mains question papers?

No, Manipal Institute of Technology does not take into consideration, JEE Main scores. It is only through Manipal Entrance Test (MET) that students are strictly admitted. In MIT, candidates have to register and undergo MET and then only they are allotted a BTech seat.

The second session for JEE Main 2024 took place for the BE/BTech paper on April 4, 5, 6, 8 and 9 in two shifts of 9:00 am to 12:00 pm and 3:00 pm to 6:00 pm. On April 12, the BArch/Bplan paper was held in a single shift from 9 am to 12 am. 

No, you cannot get into BTech at IIIT Delhi without a valid JEE Main score. The institute offer course admission based on the national-level exam scores only. Candidates who meet the cutoff mark have to participate in JAC Delhi counselling. The seat allotment is done in this admission round. Candidates who get a seat can pay the admission fee amount to confirm their candidature.

Yes why not 

Yes, JEE Main is necessary to secure entry to BTech and Integrated MSc course at SVNIT Surat. Without JEE Main, the applicants cannot take part in JoSAA counselling! Minimum required criterion as per the national guidelines is the entrance exam. BTech does not accept any other exam.
