I have been passing a Cambridge Advanced objective, spent enough time to solve listening and writing exercises but I fill that I'm not able to get correct answers for multi cloze, open cloze exersises. I could read millions of book, enjoy It, but it isn't effective for particularly task.
May I should consentrate on particularly task for ex. learn or revise each combination of preposition and it could be influence on a result. Or make a scheme each suffice transformation in each form.
What do you think? How could we prepare for exam in short period by self studying.
