I had 3 backlogs which I have already cleared in 1st year D.Pharm. Am I eligible to write 2nd year exams with current batch?

Yes,  you are eligible to write the 2nd year D.Pharm exams with your current batch if you have cleared your 1st-year backlogs before the start of the 2nd-year examinations. Pharmacy Council of India guidelines allow students to progress if all previous semester subjects are passed.
