How do I improve general awareness and general knowledge?

my suggestion is start with two methods 1. Read theory first than jump to practice set if you start with practice set it will not beneficial for the perspective of knowledge. 2. Download an app (I don't know here is allow or not for suggest another app name) regarding your exam preference i suggest you GRADEUP. or you can also buy a membership for monthly or weekly magazine for current update. The most effective part of any knowledge gaining process is Repeat what you read. there is a method i used that 1247. 1 first day first reading mark that with 1. 2 second day go through previous chapter or topic 4 on 4th day also go through topic's key point 7 on 7th day go through that topic again. As well as you repeat according this your time period will be less and you learn effectively with revise.
