can i do mcom from IGNOU and be a teacher? i did my bcom in 2017 from CU
Since you have passed B.Com from Calcutta University in 2017, you may pursue M.Com from IGNOU. But for being a School Teacher, I believe you need a B.Ed as a compulsory qualification. Perhaps then after M.Com, you may also complete your B.Ed from IGNOU or Reputed Public or Private Universities by Distance Education.
You can definitely pursue MCom from IGNOU as it's a recognized university and the degree is valid, you can use it for higher studies or even government jobs for that matter, but to become teacher at school level teacher training program is compulsory as you have done graduation already, hence you are also required to pursue BEd, then only you can teach in schools, you can appear for CTET or evn state level TETs, now if you want to teach in university level then BEd isn't compulsory, you can appear for UGC NET and qualify the same or there are state level SET exams for recruitment of assistant professor post which you can apply for.
