B.A

The exact date has not been announced but tentatively, the admissions will start in the month of June.

First of all, I would say that don't go for B.Ed. In distance mode because every school values the regular B.Ed. More than the distance mode as it is of totally practicing a profession. Besides this some universities are there if you do B.Ed. From those then it will not be considered by the schools as those are not recognized by NCTE (National Council for Teacher Education). Therefore, I will suggest you to go for regular B.Ed. So that you can be an effective teacher.

It will be difficult with this percentage to get admission in good college of DU. But, there are many colleges with where you can find vacant seat to apply and you may get admission there. All the best. Please like and follow.

Hello,
Forms are usually released in April-May. Score well and you will get a good college.
All the best.

Hello,
It varies, ranging from 2.5 lacs to 5 lacs, from college to colleges, please be specific which college are you opting? It's a good choice as nowadays DGCA is directly recruiting newer graduates for AAI and also private airlines are there.

Yes, you can. As per the eligibility requirements of the institution, any student with a minimum of 50% from any stream can apply for admission to this course.
