old sat collegeboard books

<p>So I just bought the red book and white book collegeboard. The really old ones. The critical reading and math parts are still good to study off from right? (Excluding analogies)
Also would it help me if i go through the newer blue books again? Like go through reading passages more throughly and find reasons and list why that answers correct? Thanks :D</p>

<p>It would be better if you looked into the online course or try to get some old tests.</p>
