Books for 2400 PLEASE HELP?!

<p>@tola2015 @medicsz‌ </p>

<p>I have done a couple practice CB tests on the math section and have got a 780 both times, want to get this higher.</p>

<p>Do you have to pay for the online CB course?</p>

<p>And sorry is the second of the links be more newer - hence it would be better?</p>

<p>I don’t go to school - and I teach myself all of the work if that means anything too…</p>

<p>I’m not going to get tuition either.</p>
