Dear Affan, may I know if you are talking about AP DEECET by any chance because it is akso called APDIET (Andhra Pradesh District Institutes of  Educational and Training). For this, the eligibility criteria is 10+2 with a minimum aggregate of 50% and then there is a relaxation of 5% for Reserved Categiries. The same goes with Delhi DIET . However you have a Master's degree in Chemistry. This is a Diploma in Elementary Education. Please do let us know if this is the same information you are enquiring about.
