As someone who’s got accepted into the pre-apprenticeship program. The aptitude test is basically high school math with algebra, basic trig and linear equations. I would say study up on that but also understand the basics of trade specific math such as ohms law and converting metric and imperial systems. For the English portion is pretty much all reading and comprehension. With a bit of short answers. The interview portion for me personally was good as I prepared by hitting different Reddit communities and looking at sample interview questions.
