Degree plan, GPA tool, college attached to plans

I was looking for a degree planning tool, and finally, I found it. Free for students and easy to use. It has excellent usability and a visual interface that gives a clear understanding of dependencies between the courses. As well as many other capabilities like moving, adding, deleting courses, marking as completed or locking. But the most important - Prepler validates your plan and gives you an optimal path to completion. Like Google drive, you can share it with your academic advisor or print your plan out as PDF.
