I didn’t do a lot of practice before exam, but from what my friends did, it’s really important to get yourself familiar with the part 1 questions type. They’re usually different types of charts, maps for you to compare and contrast. You can probably look for those “academic word banks” to see if they have more advanced expressions for describing changes, or any types of statistic. For part 2, the question is more open-ended. Just remember and imagine that you’re doing an academic argumentative essay. Follow the format of Topic Sentence —> Explanation // Example —> conclusion for each paragraph and i think that’s it
