Answer 1

One thing I would suggest is "learn from your mistakes".

Answer 2

Spend as much time on them until your knowledge saturates.

Answer 3

Just keep your concepts clear and just like Avinesh said learn from your mistakes
To do these both things you should do a lot of practice

Answer 4

I think sololearn courses are not enough for challenges.
So you have to look outer sources for advanced learning.
You have to improve your math skills in order to solve some general problems .
And give your best as you can.
