HI MOHIT
SO YOU WANT TO BE  A  ENGINEER. SEE FRIEND IN INDIA , LAKHS OF STUDENTS GO FOR ENGINEERING EVERY YEAR. THE IRONY IS IN BETWEEN THESE LAKHS OF CANDIDATES GOING FOR ENGINEERING FEW ARE HIRED BY TOP COMPANIES LIKE GOOGLE, AMAZON, FLIPKART ETC. AND OTHERS HAVE TO JOIN A PRIVATE COMPANY AT A VERY LOW PAY SCALE.
SO IF YOU WANT TO COME IN BETWEEN THOSE WHO ARE HIRED BY TOP COMPANIES YOU MUST BE FROM A TOP COLLEGE LIKE NIT OR IIT. 
SO COMING ON THE POINT OPT FOR NON MEDICAL{ SUBJECTS: PHYSICS,CHEMISTRY,MATHS,COMPUTER SCIENCE AND ENGLISH} IN YOUR CLASS 11 AND ALSO OPT FOR REGAULAR SCHOOLING. ALONG WITH IT YOU CAN ENROLL FOR ASKIITIANS ONLINE LEARNING PROGRAMME. AFTER SUCCESFUL COMPLETION OF CLASS 12 YOU HAVE TO GO FOR IT FROM A GOOD COLLEGE

No, donot go for dummy school at all . beacuse joining a cbse school will benifit you both in the preparation as well as in your board exam also , rather than now , board exam weightage has been scrapped , but still , there are other engg entrances , which requires board exam percentage . 
so, better join the cbse schools , and put max effort at home whatever time u have with you , in school they will teach ncert , that will cover 40 percent of the jee prep . |
rest u have to just practice these thing in home . 
and doing that also give u full confidence as well . 
TAKE PCM IN CLASS 11TH , they will help u ,. and put physical education in the 6th opt . physical edu will help in scoring more marks without studying so much 
ALL THE BEST ..
