First of all it is worth to take admissions in some school which comes under delhi to avail the benefit of 85% reservation for delhi students .But it is really ver difficult to get diya admissions in some government college in delhi unless you belongs to some elight class .But you can do some hard work to get any private college .What's the problem in taking private school (which comes in delhi) rather than government school .I am not full sure whether you or not but ,I think most probably you can chose private school .For this purpose you have to visit the school personally as there is nothing like online method to do so
