Besides everything that has been said, here are the two unknowns:
1-Will the individual test be even harder or more challenging than what they are today?
2- How about the curves? Keep in mind that these tests are actually scored based on curves. When everyone has time to focus on just one section, the potential curve could be detrimental for those just missing a few answers.
Lots of unknowns here. From the look of it, students might benefit. But I am just not sure it will. It might just become more competitive as well.
