CBSE 12th

Yes, you can be admitted into B.Tech Computer Science in the Islamic University of Science and Technology (IUST) even though you have not appeared in any entrance test, but again this is based on the admission system of that particular year.

What IUST Usually Requires

• For regular B.Tech admission (including CSE), IUST favors applicants who have a JEE Main score. The first round of counselling through JEE Main Merit fills most of its seats.

Application With No Entrance Exam.

• If you have not yet written JEE Main or any other entrance examination, then you can be admitted only under the following conditions:
  
  Vacant / leftover seats:
  In case the seats are not taken after all JEE-based counselling rounds, IUST can admit via:
  
  Entrance test of University, or
  
  Percent of 12 th board (PCM marks)
  
  Merit-based selection:
  An 80th-percentile in the 12th place qualifies you to have an opportunity during the merit or spot round admissions, though only in case you have a seat.
  
  PCM requirements:
  To be eligible for B.Tech CSE, you need to have Physics, Chemistry and Math in 12 th.

Important Points

• CSE is the most demanded branch and the applicants of JEE are preferred.
• Entrance is not assured even though it is admission without an entrance test; particularly CSE.
• You have to continue checking official IUST admission notifications to get a spot round or merit-based admission.

Final Answer

Yes, you can be admitted without an entrance exam, but not guaranteed. In case CSE seats are still left after rounds based on JEE, you may be selected on the basis of 12 th marks (80%) or a university examination. You need to apply to spot rounds or vacant-seat counselling to increase your chances to the maximum.
