Hello Aspirant

Yes, you can typically take admission in a B.Tech program even if you have a backlog in one subject from your 3rd semester, provided you have cleared it by the time of admission.

However, the specific eligibility criteria may vary from one institution to another. Some colleges might have a strict minimum CGPA requirement, while others may consider your overall academic performance and other factors

Keep in mind, that you need to clear your backlogs before the admissions start because no college accepts a candidate who still has to clear compartment papers

Hope this helps
