I have recently made up my mind to appear in the CSS 2021 Exams but I have heard from some people saying that studying at home by one’s self for CSS is very difficult and an academy should be joined to better prepare for exams. Since I am new to this I would like to ask on how I should study meaning what sort of a approach should be adopted when starting study at home.

I am fairly new to this and it feels like being bombarded with huge sources available on the internet. I would greatly appreciate if a guideline to which to follow and study from.
