Mathtutor
From Wikipedia, the free encyclopedia
Mathtutor is a tutorial system incorporating video tutorials, diagnostics, summary text and exercises aiming "to bridge the gap from school to university study (in mathematics), to revise or find the maths topic you missed".
It has more than eighty topics on seven DVD-Rom disks which you can view or work with online.
Mathtutor was developed by Tom Roper at the University of Leeds and other parties.
