I took it 3 years ago. I was nervous too, since there is so much
to study and I was more than a few years from my undergrad
classes. It is all basic introductory level science. So, what
you learned in Bio 101, Physics 101, etc. Mine had a fair amount
of Chemistry and Bio, some biology and only a few Earth Science
questions. Consider taking Biology and Earth Science while its
all fresh in your mind and you will have 3 certs (thats what I
did, and it really helped when looking for a job.
