Which 3 or 4 subject is considered for bsc physical science
dear student
According to me, PCM/PCB and a language is the best combination.
However it depends on if you are good in computer science and you scored more in computer science than in chemistry so you can use CS in best of four in place of chemistry.
Also, it is compulsory to pass one language in 12 boards but it’s marks are not considered at the time of admission in science courses.
hope it helps
All the best!!!
