Solving Approach
At this length, the average word here runs about 3.5 letters. With plenty of short words in the mix, start by isolating any single-letter or two-letter groups — those are almost always "A," "I," "TO," "OF," or "IS." This is rated hard — the substitution pattern is less forgiving, so patience with frequency analysis pays off.
