The first section is difficult because the missing words span several categories. I would recommend that you study word pair collocations, prepositions and connecting/linking words. For the second section (grammar), study passive forms, gerunds, and past tenses. The vocabulary section is easier because you can look up the words ahead of time. Be sure you know collocations (which words commonly occur together). For the reading, pay attention to the sentence(s) before and after the blank. Observe the clues from the context. The missing sentence will tie the sentences (before and after it) together. You can prepare for the listening section by making predictions about what the missing words might be according to the context of the story. This is a challenging test. Best of luck.

What I would suggest is seeing if there is an answer key to this page, or if there are more practice tests. What you can do is try to do a few yourself and then go over the questions you got wrong and figure out what you did wrong. Try to find a pattern with your incorrect answers. As far as the listening activity, what I would suggest is finding an English song and find the lyrics and have a family member or friend remove about 12-15 words, and then listen to the song and try to fill them in. Goodluck!!
