Advice for a fresh grad during internship year

In Egypt we have a whole year to practise under supervision which is mandatory to get my license.

I feel I'm not at all as qualified as my peers, I wasted uni years but I was able to graduate with good grades.

I was looking for some advice maybe a source to study to make the most out of this training year.

While loving the idea of doing endodontic procedures, I feel underqualied to practice and would love to get better.
