With CSS Exams approaching in few months, the number of times I get this question, daily, is huge.
It is such a vague question and has no answer from my side. Instead, I can tell you what CSS depends upon and if you can get that in 3 years or in 3 months, you’re good to go!

The timeline depends upon your BACKGROUND KNOWLEDGE. If you generally have a know-how about world & history and you read already, it takes less time. Already present analytical skills help. On the other hand, if you’re at level zero, it’d take a lot more time for you to develop the requisite knowledge and make opinions about events.
