Hi all,

So I am planning on taking the ALEKS PPL Math placement test along with placement tests for Chemistry and Physics. I just had some general questions:

-How hard is each test, and what should I know for each?
-Are they all online? (I already know the ALEKS test is)
-About how long does each test take? How many questions are there? (I already know the ALEKS test is about 90 minutes for 30 questions)

-They were all relatively easy basic knowledge questions, some precalc, stoichiometry, and kinematics.
-yes, all online
-I think I finished all of them in ~20min or less per exam.
