Sierra I didn't go to tuition for SEHS year 10 entry, all self study. I did a practice test every 1-2 days starting two months before the test, then when I finished that test I would go over the answers and really reflect and try to improve on my mistakes, I would take around 1-1.5 hours reflecting and learning. I would also try to mimic test conditions as closely as possible, like having a analog watch to track time, I literally printed multiple-choice sheets they give in tests just to practice filling them fast 💀
The test isn't hard, I kind of over-worked, but in the end I got to where I needed to be. Goodluck!
