Always keep in mind that nothing is difficult, it only depends upon how efficiently you carry out your work and your perseverance.
Nowadays, some schools are offering a wide and distinct combination of subjects such as humanities without opting for traditional subjects of the art steam you can also opt for mathematics. In the science stream, you can also take economics which can give you an upper edge over students of your class and add skills to you. But, it depends on the school in which you are pursuing your 11th. Also, you can opt for some vocational subjects with normal subjects and AI is the most prominent in this dynamic world.
Also, even after the tenth, you can go for a diploma and vocational courses. But keep in mind that after that you are restricted only to that course and in future, you have limited areas of working.
