It’s best to not overthink it, and just use good standard ACT/SAT Math test methodology. Buzz through and do the ones you can easily do in your head. Also do those that still use basic Algegbra, but might require just a little, quick pencil work, and you will then find you are done. Any that might be a bit more challenging, for some, like C, K, Q, & U, turn out not to be needed, at all. My Trig is rusty, but turns out it dosen’t matter. An early clue is that there are 26 clues, but only 14 unique #s.
