CUNY has become a boot camp for “high-school do-overs.”

A stunning 82.7 percent of freshmen at CUNY community colleges needed remediation in reading, writing, math — or all three — last fall, officials said.

Of the total, 78.6 percent were New York City public high-school graduates, a total that rose from 74.4 percent in 2010, The Post reported this month.

The others who enter CUNY not ready for college-level work include dropouts who obtained GEDs, private-school grads, and non-NYC residents, said CUNY spokesman Michael Arena.
