hi,

see cutoff score changes every year and it depends on certain factors like number of participants, questions difficulty level, seat matrix, number of vacancy comes , students category etc, drdo shortlisted candidates based on gate score , which follows by interview in selection of different position as per the eligibility of candidates, since aerospace engineers job is limited in India, your rank should be under 50, try to score above 80 to secure a decent rank.

Divya, as i can see you want to join ISRO/DRDO basically something great like serving the country. Well, i would suggest, you can go for MBBS after BSc zoology, but you should not have crossed the age limit of 17-25 years.

If you are going for MBBS, you can apply at Armed Forced Medical College (AFMC), Pune. This is an armed force college where you would be trained to work as a doctor in the army. Check out the official website

You can also get into DRDO, as BSc Zoology falls under one of the educational qualifications for CEPTAM exam. You can apply and write for CEPTAM, if you qualify you can surely get into DRDO. You can check official website for further notice

For joining ISRO, you educational qualification should be BSc or MSc is Physics, Chemistry or Maths only.

I hope this helps you!

Dear Renu,

DRDO had a scheme for science/engineering PhD graduates called ROSSA (Registration Of Students with Scholastic Aptitude) in which a scholar of less than 35 years of age was eligible to apply for the post of Scientist C under this scheme throughout the year. Based on his/her area of research, DRDO used to shortlist the candidates for interview. But unfortunately now,  this scheme stands suspended .

There is no such scheme in ISRO as in my knowledge.

A PhD candidate can now apply only against the advertised vacancy in DRDO/ISRO. You can check out the links
