Yes, clearing CTET (Central Teacher Eligibility Test) would be beneficial for you, even though you have a B.Sc. (IT) and a B.Ed. in Chemistry and Biology with a method qualification from your college for Chemistry.

CTET is a mandatory requirement for applying to most government teaching jobs at the central and state levels .Many private schools also prefer candidates with CTET certification.Clearing CTET opens doors to a wider range of teaching opportunities in schools across India, not just for Chemistry and Biology but potentially for IT subjects at the higher secondary level .
