How to learn English from 0 to an intermediate level?

Question

OOP

There is an urgent need to learn English, there is some amount for implementation. I passed an introductory lesson in skyeng, but I didn’t like the cost of classes, if you take not 64, but for example 4 or 8. It’s easier to pay a tutor who will cost less and more efficiently, but that’s not about that now.
I very, very want to take matters into my own hands and gradually achieve this goal. But: I'm afraid to lose time in vain and stay at the beginner level. With tutors, the problem is the same, I'm afraid he suffers for too long and so he won't learn anything.
You can tell me what to do, and there is not much time, before the beginning of May. English is needed to communicate with foreign teachers and students))

Answer 1

Singleton.
Very convenient, because each class is written independently of each other and don't get spaghetti code, try to write "crap code" with references from one class to another, in order to pass a reference to the class, and not accidentally create a new instance of the class. Although I haven't seen your code of course, you may be using OOP for the sake of OOP and writing a lot of extra stuff.

Answer 2

The Skype tutor also didn’t work for me, the sound quality is terrible, the connection slows down, an hour of classes is negligible, you need at least two.
But offline group courses + tutor + conversation clubs + daily practice in the form of reading, podcasts, TV shows, YouTube, chatting and blogging in English for six months, brought amazing results.

Answer 3

It's useless .

Answer 4

If you want to learn how to swim, swim.
I went through (bought) a lot of things, watched a lot of things, but no way, it’s different for everyone, I think the best way would be to get into an English-speaking environment and practice not 1-2 hours a day, but all day long.

Answer 5

1) think in English
2) tell something (possibly to yourself) in English. What you know well: about work, hobbies, how I spent the day. Imagine that you met a person (not even necessarily a person, you can also meet an alien) and you want to tell about your place, about life as simply as possible.
3) read books and, most importantly, retell in English.
Personally, it’s enough for me just to regularly watch webinars in English on programming (there is no one to talk to anyway, but you support the language).
