which branch is good for pcmb students in engineering is they are weak in maths
hey,
as you are weak in mathematics but having PCBM subjects then this a plus point for you , i suggest you to go in the field of biology , you can pursue biotech engineering or biomedical engineering but do not go for engineering mandating and including mathematics subject like computer science engineering , aerospace engineering , electronics and communication engineering etc.
i hope this helps
good luck!
