I can form understandable sentences, my problem is in grammar or syntax as with more slang introduction in media, sentences became less and less grammatically correct, and the spelling of some words.

other are probably run on sentences and punctuation, and forgetting words when im speaking.

I'm on a tight schedule as im already learning a ton of other things for Engineering school masters but Ielts to be honest is just as important for my situation.

So again prep time required you think? as an average for 1 hrs a day?
What about speedy learning methods? things that maybe can spot my weaknesses and fix them rapidly?
