It depends upon how much you have gained and weather you know the concepts and theories.
Because if you go with beginning of the syllabus and all preparation than it is very hard to get 180+ marks in just 20 days.
Than it depends upon the luck .
Because in 20 days you can not cover all the syllabus and you can not do practice .
I hope you get my point
So good luck

Hii

The number of days do not matter, what matters is the dedication and hardwork one has done to achieve something. If you are dedicated enough and have a good practice you can easily achieve what you want. Keep on practicing the mock tests and previous year papers to improve your result. Study well and study smart.
Do not loose hope and stay confident. KEEP PRACTICING .

All the best!!!
