hello aspirant,

OPTION 1 : Yes , you can change your school in class 10 and can opt for dummy classes , if you want to have an extensive preparation in your JEE or any other competitive exam and need to focus more on coaching materials .

OPTION 2 : Or the other option would be that you can also go to coaching institutes and to your  school simultaneously and also focus on your competitive exams like ntse or jee . That will be hectic and tiring after all , but ,In that way , you can challenge yourself for a better good and make a better version of yourself everyday.

So the choice is yours , you can choose form any of the two above options .

Good luck , I hope that this will help.
