great dedication.

but a word of caution- u might just complacent at a later stage- im saying this by observing a friend of mine- also his thinking has become limited. and u wld also then expect urself to answer every question that is given to u and that might just not happen. so instead of doing all this, what i suggest is that now that u know what u want to do, just concentrate on ur 9th and 10th- make ur basics strong; participate in all olympiads and exams to boost ur confidence.

best of luck!!!
