Is 67% in B.Tech 1st-year a good score? Do students score 90%+ in the 1st-year?

Yes, students do score 90% in the first year.

Yes obviously students score 90% or above 90% in there 1st year exam of B tech.

Yes, of course students who really work hard and are focused towards their goal and score 90% and above in their first year. 67% marks is an average score I would say. You need to maintain a percentage as per the stands set by the university/college and also for further sitting for the placements in
