General questions about SAT Bio Subject Test?

I have taken two years of Biology (Honors and AP). I am taking the Bio subject tests and have a few questions.
Which is generally easier Biology M or Biology E?
Is the time limit on this test usually a problem? In other words, do I need to rush or can I take my time?
Lastly, what is considered a ‘good score’? I am looking at Georgetown, if that helps determine it.
Thank you!!

Personally I found Bio E way easier, but it really varies from person to person.

I find Bio M easier, very little to memorize.

Bio M is easier for me; there is a lot to memorize for Molecular, but if you are accustom to it, they will all connect in some way to help reinforce your answer.
