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.
Study degrees and credit hours. Most colleges and universities award 3 Semester Credit Hours (SCH) (45-48 contact hours) for the successful completion of a study course. The number of credits for lectures, independent project work, laboratory time and internships vary depending on specific institution requirements. A standard full-time study load is usually 30 credit hours per year. Typically, in order to graduate with a degree, universities expect students to complete: 1  120-130 credit hours for a Bachelorâs degree.  30-64 credit hours for a Master's degree.
