The first thought is that "high school points" are another word for course credits but even at 3 points per semester course, 240 points would equal 80 semester courses which is double the typical courseload that a student would take during 4 years of high school.
It would only make sense if a semester course were worth about 6 high school points (6 x 40 = 240).
But, be careful, this is just a wild guess. It is highly advisable that you seek help from someone familiar with the specific situation.
