Hi,
To become mechanical engg. you need to focus a lot on maths and Physics(Computer knowledge is an advantage).
Choose course involving these three subjects, in achool.
It is a very interesting field and if you work hard you will be successful .
Read a lot abut machines and the way they work - shortlist a list go colleges to join post XII or junior college.
Start working on entrance exams and once you get into the college, identify your interest and be the best in it.
Attend as many mechanical fairs as possible.
Nothing will stop you- good Luck.
