Beet!

I want to go in [to] London,in [to] school BEET to learn [take an] English language course. whether it can help me?what do you think?

I am re-writing this because it can be better arranged to make a smoother sentence. 

[ I want to go to BEET, a school in London, so that I can take an English Course. Do you think it will help me ? ]

--, a school in London,-- if something could be left out, such as this, you can put it in a comma, as long as the sentence still makes sense if you were to ignore the things in commas like this. 

I have not been to London yet, but I hope you are able to make it to BEET. Good luck, or as the English say "cheers".
