<p>Invoyable, you’ll find that every teacher grades differently. I’ve been in classes where tests count for as much as 90% of the grade, and I’ve been in classes where tests count for as little as 25% of the grade. Just doing well on tests helped me a ton in some instances and not at all in others. It’s nice when tests count for a lot, though; I slept through statistics and finished with an A+, and my teacher didn’t care.</p>
