Dear Student,

After taking math as your additional subject with PCB (Physics, Chemistry and Biology),  you now have PCMB as your subject combination, so you can go for B.Tech. in any branch you wish to as you fulfill the eligibility criteria required for joining Engineering which are as stated below :-

• Candidates must have passed their 10+2 exam from a recognized board with Physics, Chemistry and Mathematics as their core subjects.
• They must also have secured minimum aggregate marks of 60% in the above subjects combined.
  
  Most admissions are done based on the student's performance in the entrance examination like JEE Mains and Advanced, and other entrance examinations like BITSAT, WBJEE, SRMJEE, etc. that are conducted by particular institutes. There are also state level entrance examinations for B.Tech. like GUJCET.

And since you now have pcmb, you can opt for both engineering as well as medical fields.

Happy Learning!
