If you have qualified CTET under the OBC-NCL category but applied for the EMRS TGT post as a General category candidate, your candidature is generally not rejected only because the categories are different. What matters for EMRS recruitment is the category you selected at the time of filling the EMRS application form, since that is the category under which you will be considered for merit, cut-off and reservation benefits.
Your CTET certificate remains valid for all categories as long as you have scored above the qualifying marks. CTET does not restrict you from applying to any recruitment under a different category. Many candidates qualify CTET under one category but apply to different teaching recruitments under another category based on their preference or documents.
