Is it possible to learn English in 3-4 months?

Question

IT education

There is an opportunity to go abroad, namely in the USA and the average GPA score is 3.3-3.5, but there is one big obstacle - it's bad English and at least at the moment I study English 7-8 hours a week and have risen from zero to about pre-intermediate intermediate but you need to write TOEFL for at least 90 points
In the winter for a month, I hope to go to England to live with a family (by the way, does this help? I mean a family) and get there, but I need your advice and methods, everything you know
Is it still worth preparing for the SAT ACT if you ready for TOEFL SSAT(Subject SAT) ?
Is it worth it to hire people who will deal with papers?
And just English learning materials
Thank you in advance

Answer 2

English in 3-4 months?

It's unrealistic. You won’t learn even in 3-4 years if you ask such questions.

Answer 3

3-4 months, in an easy way, the main thing is to listen to a lot of different speech (movies, TV shows, lectures, news) and memorize it.
Grammar is secondary in learning a language, it will come by itself with time, you should not mess around and be distracted by it.
