Teacher

You may go for any degree certificate or diploma course like D.El.Ed, D.Ed, B.Ed, NPTT, etc.
They all are 2-year programmes and if you are good in performance, you may get a job in a good private/government school. Best of luck.

You may opt for NPTT course, Diploma in Education, or B.Ed from any good university because schools prefer the degree.
It's better if you go for B.Ed because NPTT and Diploma are also 2-year courses like B.Ed but B.Ed has more value. The minimum eligibility for B.Ed is 50-55% from DU.

If you want to be a lecturer, apply for UGC NET examination.
But for this exam, you must be post graduate. So do Masters in any special subject as in English, management, etc.

Hello,
First of all, you do P. G. in a renowned institute (like IISER, IISc, ICT and IIT). For lectureship or Ph.D., give the exam of CSIR (Chemical Sciences).

Hi, for becoming a history and geography teacher, you should have had chosen BA. But, you can still do BA and get graduated, but you know it'll be waste of time and efforts. Try choosing a commerce subject and become the teacher of the same. For becoming a teacher, you need a B.Ed degree. Thank you.
