The reading section of the ACTs is kind of a joke. Do you know how to read? Have you read important literature before? Do you know how to answer questions about the things you read and synthesize?
If you answered no to the first question, I do not think you’re ready to hire a test prep tutor. But if you answered no to the rest of the questions, I can help you! In the meantime, I would start practicing by doing simple things like reading short scholarly articles about literature, reading one article in the news every day, and practice reading faster and faster. You’ll do better on this exam if you have confidence in your ability to read and synthesize information quickly.
