<p>Algebra II isn’t on the PSAT. What about permutations and combinations, number of pairs, etc? Would they be considered numbers and operations? Where do they draw the line between Algebra I and II?</p>
<p>Bump. Anyone know? I can’t be the only one wondering about this.</p>
<p>You can occasionally get a combination or permutation of the SAT. If you see one on the PSAT, it should be very simple.</p>
<p>You never really need the formula. If you are given “5 choose 3”, you can solve it logically:
5*4 = 20, but you divide by 2 since pair (a,b) is the same as pair (b,a).</p>
<p>discrete math.</p>
