Dear Akash,

first you should get a good marks in 10th class.

Then take admission in 12th with PCM(physics ,chemistry,maths).

no need to go to that school,where attendence is too much compulsory. I personally advise you to take admission as a dummy student.

join a well recognised institute for JEE Advance preparation for two year course.

like

• FIIT JEE
• Allen
• Prerna

or with which you and your  family are comfortable.

you can sit for JEE advance two times 1)at current year of 12th

                                                        2)next year of 12th 

JEE conducted into parts 

• JEE main
• JEE Advance

If you will qualify JEE main then only you will be eligible to JEE advance.

after joining any coaching center focus on all three subjects basically on numericals.

but you have to also read basic theory because many time questions are asked directly from theory portion.

here there are some books given which can help you-

• physics-1)concept of Physics by HC verma(Vol I and II)                                                                        2)IIt JEE Physics by Arihant                                                                                                    3)Fundamental of physics by David Halliday
• mathematics-1)plane trigonometry and cordinate Geometry of S.L loney                                                      2)All books of arihant publication for JEE advance
• Chemistry-1)P W Atkins                                                                                                                        2) Physical Chemistry by OP Tondon                                                                                        3)O.P Tondon Organic Chemistry                                                                                            4)J D Lee

For Now you you focus on mathematics,physics,and Chemistry strongly.

try to solve numericals more and more.always Read NCERT.

clear basics.

Hope you understand 

thank you so much

All the very best.

Hello akash,

HARD WORK AND TIME MANAGEMENT

study well, clear your basics, score well, forget everything for 2 years if you really want to crack jee advance, develop interests in subjects without any interest it will be all boring for you.

I hope this helps. all the best.
