Are there any legitimate free ACT online prep courses?

<p>I'm taking a jab at the ACT this October (my first time), and I really don't want to spend money on a prep book or online course so soon to the test date. My SAT is proportional to an 30 on the ACT, and would be satisfactory for most colleges except for the ones that require/recommend SAT Subject Tests. I just need the ACT to "cover" for those Subject Tests, but I still want to score at least 30.</p>

<p>Are there any legitimate but free ACT prep courses online?</p>
