which jobs are available in DRDO for 12th science students
After 12th you can't get into DRDO for any post. You need to do graduation either you choose B.Sc or B.tech.
After Bsc you can write CEPTAM where you can get a tier 2 post or in simple language a assistant job.
After B.tech either you can Write GATE or you can write DRDO entrance conducted by DRDO itself for Junior scientist role.
