hello,

your question is not clear to me. I assume you want to whether he can take admission in english medium and another central government board. the answer is yes, he can switch to cbse and icsc or osc board. however all boards have different question pattern for 10th grade. cbsc has both theoretical and mcq questions. and THis goes for icse and isc board. Central education board has more number of mcqs compare to wbbse board. however I would suggest you to take admission in cbse as cbse syllabus is followed by maximum all india exams.
