Hello,

If your query is regarding JEE MAIN then yes, you can apply for both B.Tech that is paper 1 and B.Arch that it is paper 2A. The examination will be conducted on the same day but in two different sessions. If your paper 1 exam is scheduled in the morning session then Paper 2A exam will be scheduled in the afternoon session on the same day. There will be a break in between morning session and afternoon session. You during the break you can have your lunch and then appear for Paper 2A as per the schedule timings. The results for paper 1 and paper 2A will be declared separately. If you have qualified in both the papers you can take admission in the course in which you are the most interested.
