I recommend taking both and checking with the schools you plan on attending to see which one they prefer for entrance. Some will say one or the other or both. Also on my college preparation blog, Planning and Preparing for College (Scholarships, Internships, Etc) I have a section on the right side for ACT/SAT along with practice url's, info, tips, etc. Utilize the practice url's to built up your speed and time. I also have a link to the 1,000 words to study for for the SAT.
Please take the time and visit and the info should be of value to you. I wish you success of either or both exams. The next one of both is scheduled in October. You can still go in as a walk-in on the day with your packet completed along with your total fees due (in a check/money order).
