are your reports and extra curricular good? If so, for the edutest, I recommend you practice hard vocabulary lists for verbal reasoning, you can find many on quiz let for free, keep revising them. Numerical reasoning is basically like GA, so practice GA books and questions, you might be able to find them online for free.
For writing, it’s always creative, so it’s always a narrative. I recommend you practice 20-30 minutes of writing every day. To improve your creative writing, you should watch a lot of fantasy/fictional movies or read fiction novels, to help you gain better ideas because this helped a lot of my friends gain entry.
For maths, you should practice time management, because there’s a lot of questions for very little time. The maths basically covers the syllabus of your current grade in depth, so focus on learning and grasping your maths syllabus very well then practising the questions.
I’d say that the edutest prep pack is a poor reflection of what is actually in the test, so I would tell you to go and purchase some scholarship tests practice which include services like giving feedback if you submit creative writing, because they’re a more realistic testing surface for the edutest than the edutest practice papers because they are quite easy.
also I heard about selective specialist and I heard good reviews from it so you might wanna check that out too, it could be handy especially for hast
hope this helped
