Preparing for sat math with subject tests?

<p>Is preparing for the SAT I math with SAT II Math level 1 and 2 barrons books viable? I want kill kill two birds with one stone and am in a time crunch, would I need any additional practice with the SAT math if I practice for the subject test. Are there any better books than Barrons for the math subject test as well? Sorry if my questions are all over the place.</p>
