I have studied till 10th grade, but due to many reasons I can't go to college or school. I want to study science by myself. How should I start? Is it possible to do it all by myself? Which books/sites should I refer to?

Science thrives best when it can be shared among peers. You can study many resources alone, but you should always have a way to communicate and share with others studying the same things.

11th grade seems like the most obvious starting point to me.

I would recommend online classes or a "flexible scheduling" high school, if you have access to one.

You could complement self-study with an interactive MOOC course (e.g. Coursera, Udacity) where you would interact with fellow students and an instructor/teacher assistant. These courses are free to enroll and sometimes they even give you a certification of completion at the end of the course.

Distance learning is a possibility. I work for a British college (If you ask I will give you the name) that allows students to submit their homework via an online system and has some support via email. In this instance it is AS and A2 maths, physics and chemistry. The students are both UK and international.

 

-There are of course other colleges and universities that offer a similar service.

 

If you go down that route, you will miss some peer interaction and the dynamic of tutor support in person. That said, the method must suit some peoples' circumstances. The students do okay overall.

 

The cost of distance learning is something you will have to take into account.

the textbooks are great actually. I recommend the textbooks. And Dr.Google
