Is PCMB a right choice?

Hey guys, I am a class 10th student. I want to be an engineer hence wants to opt PCM in class 11th but I have a lot of interest in biology and hence my mind is diverting towards PCB so I have decided to go for PCMB. On doing more research, there are some coaching institutes such as ALLEN AAKASH UNACADEMY in Kota and CLC PRINCE and MATRIX, SIKAR which offer courses for PCMB. Is this a right option or I should only go for PCB OR PCM. Seniors please help as only 2 3 months remaining and a lot of confusion is there for stream selection. Drop your suggestions 👇
