I would say keep learning now, because I have had the course for just a few days, (I received it Monday) and I am already able to photoread books and experience spontaneous and manual activation. It shouldn't take too long to learn, because your brain already has the capabilities to do it.
I am currently attending school, and though it's the beginning of the year, I've been so busy with school work, and it just keeps piling on. But I always find time in between the time I finish my work, and before I sleep. I usually get one to two free hours per day, excluding dinner and stuff like that.
That's just my view on it, but if you find it keeps interfering with work and your grades might be suffering, you might want to postpone photoreading.
But just adjust to your schedule however you need to and you should be fine.
Hope I could help
