Since you are pursuing PG in English you can definitely apply and are eligible for PGT in English in KVS, navoday Vidyalay and all school exams. Do you have done BTech in ECE and B.Ed in maths and Physical Science they will not impact in any way during your interview in the exams. But you have to definitely mention that you have done graduations in ECE and B.Ed in maths and Physical Science during application or during the time of interview in the examinations. Thank you. Good luck.
