What are some additional resources for QR other than Math Destroyer?

I have the same question? Is the math section of Kaplan Blue book + math section of dat destroyer good enough to get an 18? I really dont wanna purchase math destroyer and I dont have the time to go through it.

For additional resources I got Barron's SAT Subject test Math Level 1? are these all good enough? Anyone wiht a good QR score and used stuff besides math destroyer, please chime in on what books were helpful.
 
math is math is math. look at what the ADA says is contained in the math section. then look at the SAT book and see what topics they cover. if they overlap, congrats.
 
I have read in a few great breakdowns that Barrons SAT math workbook is helpful so I have been working my way through that and it's cheap. However, there is no trig, so I plan on using khan vids for that ;-)
