Natural Sciences study resources enough?

[lmech]

Any 1 of these:
DSST Astronomy (not bad if you like Astronomy)
DSST Environment & Humanity (this is the one I'd recommend)
DSST Geology (only if you're a serious Earth Sci buff - this one's tough!)
DSST Physics (haven't taken it, no suggestions)

I think that's it for DSST 3cr Science.

DSST Physical Science I has a great pass rate, also
