Hi Aspirant!

I am considering that you are asking " Which is the best course after 10th to become a software engineer?"

As you want to become an engineer then you must choose science stream with physics, chemistry and mathematics (PCM) subjects for 11th and 12th class. You can aslo choose computer science as your optional or addituonal subject in 11th and 12th. this will help you gain basic understanding of the programming languages which will make concepts easier later in the bachelor degree.

Thankyou!
