I require an advice!

I'm an ambitious teenager presently at class 12.I have a great passion for programming as well as for Ethical hacking.I dream to get to Microsoft and contribute my parts as a windows 10 developer.But my academic levels are not up to the mark!There is no way that I will be admitted to any of those Government institutions for my further studies.I would like to proceed with C.S(B-tech).Actually I'm not able to find time for my studies as I'm engaged in those online courses to make my ideas to life in the form of apps!I really hate physics and chemistry and have a great passion for mathematics and computer science.Can I get to Microsoft with just the talents that I develop?
