Learning to read or write is a lifelong endeavor. For many students, the process of getting to that point goes through a number of steps, from studying to memorizing, and then finally to reading and writing. When you put the entire process into a single computer-based system, you can see how it can be incredibly difficult to make progress.
I’ve heard that many, many people have learned to read or write as a result of attending college. But while there are certainly some exceptions, the vast majority of people who enroll in a program of study are most likely going to be enrolled in a course or a special study-abroad program.
