Thanks.

Social Science would be a better option, if you have studied commerce stream in class 12th with subjects like economics. Otherwise, it would be better to apply for PGT for commerce teacher post. If you are applying for TGT, then you won't have option for commerce subject, as it is only taught at +2 level. Hence, social Science is the only option or you can also go for Maths if you have studied Maths at +2.

Yes, if you are qualified in CTET then you can apply for teaching job in Rajasthan.

No, You need to pass both the papers of the respective examination to be considered Pass. If you are unable to appear for the first paper, You can attempt both the papers in next attempt. However, passing single paper does not qualify you for the examination.
