<p>Just do all practice tests in the BBs (11) and the official online course (10) and the yearly official practice tests. I can glance at a sentence and identify errors without much difficulty so MC is my strength (only 1 wrong in Dec test). To write good essay (I got 11), follow the “How to Write a 12 Essay in Just 10 Days” link above. It’s formulaic but it WORKS. Of course a bit of luck, esp on the essay prompt, is needed but not essential for a good score (I’m an international student)</p>
