Reaching a minimum goal for quant

[a380038]

Without any real study time my verbal scores are in the 45-47 range so I have no real concerns in that area, but my quant scores are sub-40. Since I started studying for the GMAT, I've had trouble judging the relative difficulty of quant questions. Can anyone share a strategy for mastering the quant section to a minimum goal of 40? I realize everyone wants to shoot for the stars, but I'm afraid I won't be able to reach the more difficult questions because I haven't mastered the basics.

I've started working with the magoosh practice questions which have been helpful, but I'm open to more suggestions.

Whats your educational background ? A lot depends on that - if you are from quantitative background than 1 month with Manhattan GMAT books is sufficient.

I have a finance degree but I haven't taken a math-related course in 7 years.
My main concern is that I don't waste time studying the more difficult questions when I haven't mastered the basics. It all seems relatively easy but I make a lot of simple errors that I should be able to avoid. I will take a look at the manhattan books.

Thank you,
