SAT Bio E/M WITHOUT AP Bio?

I’m a junior and taking AP Bio next year. I’m taking the SAT subject tests in June, should I take Bio E or M? I’ve already gotten a book but I just want to know which one is easier for someone who took honors bio sophomore year and haven’t taken AP yet.

I’ve researched and most people say E is easier. True or nah?

I have heard that M is easier… You can definitely do it and achieve a high score you just have to put in a lot of work… GOod look
