Yes, it is possible for an SC category student with an 84.60% in 10th grade to be selected for computer engineering, but it's not a direct admission based on 10th marks. Admission to computer engineering, especially at the IIT level, usually requires completing 12th grade with specific science subjects and securing a good rank in the JEE (Joint Entrance Examination). The 10th-grade marks are a prerequisite for appearing in the 12th-grade board exams and the JEE.
