Suitable for those who are short of time.
This mode has 550+ hours of video (compared to 850+ hours in regular mode).
Some video modules are replaced with QBank modules. These videos are simple topics that do not need video lessons.
If you watch at 1.5x speed, you can easily finish this in 100 days (assuming 4-5 hours per day are being spent).
