what to do with wrong answer journal?

I mean I know, u have to see why u got certain Q wrong but I dont understand how to utilize my WAJ. is there a way? how do u all revise it effectively? Any tips and tricks?

PS. I use CollANote app for my notes, I have created a seprate doc for WAJ. I usually take a picture of question (including AC and everything) and then I write the technique that instructor uses.

Is there any other effective way?
