Answer:
The Aspire Test tests your proficiency in English, Reading, Mathematics, and Science.
Step-by-step explanation:
The ACT is a more advanced test versus the more common SAT. The ACT features 215 questions, while the SAT has just 154. It is more worthwhile to take the SAT over the ACT due to the better odds of a preferable score as well as it being easier to study for due to it having less questions and being more popular. It would not harm you to have scores for both, but if you're treating it as a one or the other sort of thing, I would go with the SAT.
As a side note, keep in mind that you will need to focus on more than just your SAT and/or ACT score for your college application. Not only is a strong GPA important, but extracurricular too. In increasing numbers, colleges are looking at the more human aspect of applicants versus the raw, impersonal data of grades.
