FYI, there aren't too many Main Idea Questions on the ACT. Just remember to
- IGNORE the minor details
- FOCUS on the main point or central idea
- Ask yourself "What's the central theme?" of the passage
- Read and reread the 1st and last paragraphs to get the gist
WARNING - the sound quality is not very good but keep your copy of the ACT Free 2012 -2013 practice booklet on hand and take good notes...
