Hi. It seems to me that you will be much better off using the help of individual tutors, which you can find on the Wyzant website or read a great review on this site https://edureviewer.com/tutoring/wyzant-com-review/. This online help will allow you to improve your knowledge in any academic disciplines and this solution is quite inexpensive, but again it all depends on your training. For example, an experienced online algebra tutor can be found from $ 30 per lesson.

Many teachers believe that you can not study for a long time the day before the exam. Do you agree with this?

Many people think that in order to fully prepare for the exam, only one last night before it is not enough. It is not right. You need to prepare for the exam in advance. For example, I bought courses https://studymind.co.uk/. I trained for about half a year.
