Dear aspirant !

Hope you are doing great !

Yes,one can join Engineering or B. tech (Bachelor of Technology) after complete your 12th standard with physics,chemistry,math,Biology(PCMB) . Only +2 science stream students are eligible for Enineering course.so you are eligible for join Engineering.

Generally, students take PCMB to keep both the doors open ( NEET and JEE/AIEEE). However , most of the students either choose PCM/ PCB because it is a difficult task to go ahead and give proper time to both the subjects..
