OK,I added you on steam so please recieve it.
I've never taught anyone who is in top 200 so please wait a bit to make myself clear how to teach you.
I think I can post my thought in one or two days 
I want you to give me your own replays or someone's replays you want to research.Any videos on Youtube (or so) is welcomed.
And could you add some comment on these replays?
I think you are good enough,so you don't have many points of improvement.
Instead of that,I think building your own strategy will be the aim in my class.
There are many meta,many guides, and many static tactics in this game.Many people praise them and use them with no doubt.
In some ways,they are right.Meta makes you easier to understand,guides are useful,and tactics also helps you lots.
However,all of these are for beginners,not for high ranked players.
I don't mean that high ranked players don't use Meta.I do mean high ranked players depend less on the thought of others.
There are various types of matches on uppor level because nobody plays as seeing textbook.So you have to adapt various types of situations.
There are no tips on "Semosky 1v1 against jove",there are no hints on "how to counter CaptainSPrice's 141 population cap tactics".If you want to win,you have to think for yourself.
In fact,no one teaches how to beat these top players.You can just see it through Twitch or Youtube.
So,I think it is very important to learn from watching someone's (or your own) replay.
I believe thinking for yourself will let you know what is good and what is bad in this game and after piling up these judgement,you can build your own strategy instead of imitating someone's rigid tactics.
If you give me your own replay,I can also find your mistakes.
