hi Harshitha
BSTC and PTET are 90% same. both are 2 yr course, Rajasthan course, for teaching, same eligibility (12th pass with at least 55%), can be teacher up to class 12. but there are some difference in that 10 %.
BSTC is a certificate course after which you cant do any studies based on this certificate.
PTET is pre teacher training course, after which you can take up BEd and become a teacher even for higher secondary school.
though both are mostly similar, i guess PTET is more worthy than BSTC.
i hope this answer helped you
