Degree

Diploma course is very useful. You get more technical knowledge in Diploma but again it's not degree. The kind of salary you will get on diploma basis it will be in the range of 15-20k.
And the salary you will get after degree will be obviously more than Diploma.
Again if you are thinking of doing a Diploma and the degree then risk is on the Diploma marks you get.

Just visit the website www.djsce.ac.in and keep a check on the notices uploaded by the college for direct 2nd year applications. From dates of application to cutoffs everything will be put up there. Constantly keep a check there.

There are many courses available in many public and private universities in The United States which offers Masters of architecture (3 years graduate degree programme) for candidates who do not have undergraduate architecture background. You can also contact their respective departments for detailed information about the course structure.

B.Ed should follow a degree. It is altogether a different degree programme.

Your question is vague, please specify your academic profile.

Hi,
Currently, it's debatable and not recognised any longer. As per UGC, duration of M.Sc in India is 2 years therefore a 1-year M.Sc degree is not present in India.
