I am using the Kaplan Foundations of Math as a starting point to brushing up for Quant. I am missing quite a few as I go through and looking for advice on how I can master these foundations since these are the building blocks to solving GMAT questions.
Is looking for similar problems online and just solving a bunch in bulk the best route when struggling with these basics?Ch. 1 Arithmetic drill set - 27/30 due to exponent and radical multiplication
Ch. 2 Divisibility drill set - 22/35 due to some factorization, larger prime number identifying, and questions like If n is divisible by both 196 and 15, is 270 a factor of n?
Ch. 3 Exponents & Roots drill 1 - 4/7 stopped here because I was getting discouraged. Mostly got multiplying/dividing exponent rules wrong here
For context I am in my professional career and out of school for 7 years, trying to brush up and take my best shot at the GMAT.
