yes you can do bed. also meanwhile you can join as a teacher in any college.

Yes, you must do B.Ed to get a good permanent job as a Teacher. You can surely do it. I would also suggest you to give UGC NET exam (held twice a year) and if you clear it then you would be eligible for Lecturership also. You can also give SET (State Eligibility Test) of the state in which you live
