April 27 (Reuters) - Grand Canyon Education Inc (LOPE.O), posted a quarterly profit that more than doubled, beating analysts' average estimate, helped by strong enrollment, and raised its full-year forecast.

For the second quarter, the provider of online and campus-based post-secondary education services forecast earnings in line with market view and better-than-expected revenue.

The Phoenix-based company reported a profit of $6.9 million, or 15 cents a share for the quarter ended March 31, up from $3.3 million, or 9 cents a share, a year ago.

Revenue rose 65 percent to $59.0 million.
