When the moon is full or new, the gravitational pull of the moon and sun are combined. At these times, the high tides are very high and the low tides are very low. This is known as a spring high tide. Spring tides are especially strong tides (they do not have anything to do with the season Spring).They occur when the Earth, the Sun, and the Moon are in a line.The gravitational forces of the Moon and the Sun both contribute to the tides.

The number of courses you may take in a semester is dependent on many factors, such as your time availability and your school's course load policies. To be considered full-time as an undergraduate, most schools will require you to take at least 12 credits, which is equal to four three-credit courses.
Undergraduate students are considered full-time students when carrying between 12-17 semester hours (s.h.). Credits in excess of 17 s.h. are additionally assessed at the per semester credit hour tuition rate. NOTE: Student refunds will be issued as a credit towards tuition and fees for future registrations up to one (1) year after the end of the semester in which the withdrawal took place.
