Count the F’s. One sentence, 10 seconds on the timer, then the answer with every F circled. Most people say three; the answer is six, because the F in ‘of’ (three times) gets skipped. Your brain reads short, common words as one shape, and ‘of’ sounds like ‘ov’. It’s not an IQ test; it’s how fluent reading works.
Did you count all six? Yes or no? 👇 Follow for a new test every day.
