Hello Student ,

If you change your school then change it in the class of 6, or at class 9, or at class 11. Otherwise you have to break the rules and regulation of  state Education Board. Education will be in a dilema. At the time of changing your school the stream you have taken after class 9 that should  be   continued in your new school curriculum. If you have arts in your old school then you should  take it for the advantage of your future progress of your education. So subject matching will be the same as you have in your old school and now in your new school also.

Hope this will help.
