hello preeti,

yes,surely you can do this. because i think self study/preparation is better than going for any coaching.

first divide your day to day time schedule according to the chemistry,physics and maths (in syllabus).wake up early and start your day with maths,then take physics &  chemistry.first cover the portion of your senior secondary board syllabus and try to solve ncert books.this is enough for short time preparation.dont get panic and stressed, handle the problems with the general idea.

all you need to do is smart work.

all the best!!!!
