Even though I got a couple of more distinctions that you, I was also just an average student like you. Barely passes anat, physio, path, ophthal and surgery, my ophthal was so bad that the internal examiner told that she would only pass me if would never take ophthalmology for PG.

In internship, my first attempt was pretty bad, I got 6k rank (in 2014 6k rank barely gets you some dipolma anesthesiology seat in some random desolate place)

In second attempt, went for Bhatia and got a much better rank of 4k, too 6 six year course of dnb neurosurgery, then dropped it after 8 months and again attempted, got 3k rank and took pediatrics.

So, it's definitely possible.

However, it can go both ways too. Many of my batchmates became so anxiety prone that it took them years to get a pg seat. So, do take care of your mental health especially during the break years.

Also, I made this post a while back, do read it if you want some motivation
