This is very much like me. Going through same process until it gets into the head. However, I feel like I need to remember some fundamentals every now and then.

This is very much like me. Going through same process until it gets into the head. However, I feel like I need to remember some fundamentals every now and then. As time passes, our brain can barely hold enough information. I do not want to lose what I know. So, I am stuck in this limbo of retaining what I learnt and using it. Because not everything I learnt gets used everytime at all! It happens over different period of time. And when it happens, it just sucks not remembering these! Most relevant: DSA and interviews.
