Hello there!
Greetings!
I think you are in class 10th and you are worried about which stream you should go for in intermediate, if you enjoy reading both maths and Science then you can go for science stream with PCM i.e. Physics, Chemistry and Mathematics in your intermediate and later you can do graduation in any subject of your choice depending upon your future interest in the subject, you can go for engineering as well , as engineering is simply the application of science and math to solve problems.
thankyou
