If you really want to get points quickly and time is tight ... I think it is actually more useful ... Computer classics seem to be fine without teachers. Then say that classes without teachers are really ordinary.
Finally, I just don't think I've been to either side ... If someone comes to communicate with you, don't listen to me. I attended a large class of 120 people in New Oriental. ....
PS, personal experience ... If you really don't have much time before the exam, first look at the forecast and see if the date of your registration for the exam is auspicious ... If it is a new topic day, I can't help it ... Take a good look at the old topics and write both your composition and oral English (if time permits). If you don't have time, at least make an outline and try to read and listen as much as possible. Then 1 day 65438.
I think so, too. If you have more than 1 month, there is still room for improvement. Every day, honestly TPO+ dictation+words, read the original English magazine when you have time, and never give up ... If you only have half a month or less, do TPO+ read machine classics.
Again, I have never been to either side, for reference only.
