My IELTS Challenge

Recently, I've found a new challenge - passing the IELTS with a score of at least 7 on each of its/the four components. I've been studying intensively learning for two months, and have improved my listening/reading from 4.5 to 7.5 on average. But I'm a little bit stuck in speaking. I've learned more than two thousand new words, but can't use them in my speaking. I've improved my grammar, but I speak with a lot of mistakes. I have lessons with proficient, strong teachers, and they help me considerably help me.  (I thank them.)  But I'm not a very patient person. I want to speak fluently tomorrow. :)

I'd been thinking and searching for a magic approach quite a long time, and finally decided that the best way for me is to learn naturally and take my time. But in order to stimulate my speaking, I decided to write 100 part-two-question and 500 part-three-question flash cards. (I use flash cards in learning and would recommend them -- for example, Anki.)  First of all, it will help me to remember some common phrases, connecting words, idioms etc. Secondly, I'll have time to choose "advanced" words for answers and to get used to them. Thirdly, by answering and checking these cards every day, I can improve my speech. And of course there is a chance of having a similar question on the exam. :) But, as always, there are some disadvantages - I shouldn't memorize answers, I should use them only as an example, and because it takes a lot of time, so I'm still procrastinating, and haven't started.  [1]  :) But when I manage to answer any card fluently, I'll go and sit the exam.

[1]  I personally am not used to seeing the verb "procrastinate" followed by the infinitive of another verb.  Though other people sometimes use "procrastinate + infinitive", it sounds awkward to me, so I have suggested another structure which I think is much more common and better sounding.

Your post was excellently written.  For the most part, it was both correct and natural.
