What I did for the math portion was practice calculating medium level math in my head. Like percentages, long division, conversions, etc. And I break up math problems and round off long decimals because it eases processing power and leaves you with a good guesstimate still (especially if you're short on time). Use all of that piece of paper they give you for the test. Also I liked this free website. The practice tests were more difficult and much shorter than the actual test but still got your brain thinking about what you'll have to do. Free TEAS Practice Tests | TEAS - Test-Guide.com
