ACT VS SAT difference in strategy?

<p>Is there any significant difference in the strategy that one should use for the ACT VS SAT. I know that the ACT math includes more topics (like Trig), but I would think that any skills form SAT prep would be useful for the ACT. Can the same be said for reading and writing sections? Do these sections need a different approach then the SAT? It seems that you have to be very fast on the ACT to finish the test.</p>
