Most of my students struggle with the ACT Reading section not because they can’t read, but because it is so difficult to manage the short time given. This is entirely understandable, the ACT is a unique experience that is hard to prepare for. Think about it this way, in the real world people normally don’t open up the New York Times and give themselves 5 minutes to read the top front page article. That would be just weird. Even if you wanted to do this, you wouldn't know how long the article should take you to read anyway. With every second counting, guessing an article should take you 6 minutes to read when it really should be 5 minutes can be quite costly.
This is why I love JSTOR’s, the world’s leading digital library of academic journals, daily (free!!!) blog based on the papers they publish.
Sourced and written by their own high-quality writers, the content is on par with what you may see in an ACT Reading section. Even better, they divide the website topically so you can practice the passage type (expect fiction) that gives you the most trouble. Best of all, each article is listed with a reading time so you can time yourself even if don’t have time for a full section. Perfect for when you just have 5 minutes to practice.
JSTOR’s blog is the best free website out there to help you prepare for reading the ACT’s deep academic content under time pressure.
