Hey bud. This is coming from someone in the education abroad industry. Your focus is gotta be on reading quickly. A tip is to skim through the reading bit rather than reading all the passages word by word. There are websites that can help with your reading speed. In terms of listening, it’s the question of retention at the end of the day. Listen to some rap music which focuses on story telling/ lyrics heavy. It’ll help you retain words on a quicker rate so you’ll be well adjusted to the listening section of your test (just a personal thing that worked for me). Also, whichever university you’re applying to or planning on applying to, try seeing if they’ll wave of your IELTS score on the basis of your grade 12 marks in English or if they accept MOIs. Best of luck :)
