did I pick the wrong book for pre-calculus ??

<p>hi all
I am a senior high school student preparing for college, so I wanted to do the pre-calculus course and picked “pre-calculus for dummies”.
I feel like I picked the wrong 1.
what do you think.
I have reviewed the book “pre-calc know it all” but it seems really huge.more that 600 pages.!!</p>

<p>tell me what do you think and please if any 1 have used this book before tell me what do you think.</p>

<p>best regards;</p>
