After class 10th comes the most crucial time of a students life. Now this is the time where you need to choose which stream you are going to carry on with. An that would affect your future studies.
You have options like Science, Commerce, and Humanities/ Arts.
Science : This has two options available. One would be Medical i.e Physics, Chemistry and Biology. This would lead you into medical field after class 12th. The other option available is Non- Medical. This would include Physics, Chemistry and Maths. If you wish to go for Engineering or architechture, you must choose this field.
Commerce : This includes the subjects Accounts, Business studies, Economics. Incase you find yourself interested in business or accounts this is the stream for you. After 12th you will have options like B.Com, BBA, CA, etc.
Arts/Humanities : In this stream the options are wide, there is a lot of variety. You can choose a mixture of subjects as per your interest.

It is suggested that you do a little bit of research before you choose any stream. Make sure you know very well what you wish to do in future and then only choose the stream based on your interest and future planning.

Hope this helps
