Was wondering if I should spend the time meorizing this Pfr stuff.

I highly doubt it. It seems like most people don't really get anything on plants, and if they do, it is extremely basic (how it was for me). I chose not to memorize that stuff. There is such a wealth of knowledge on the DAT that it just usually isn't worth the time to hit the obscure stuff!

Probably not worth it; just know that blue light opens up stomata, phytochromes are used to detect light, Pr changes to Pfr if exposed to red light, and Pfr changes to Pr if exposed to far-red light.

That's all I remembered and I did not see a thing on photoperiodism on DAT. That is not to say that it won't be on there, just not likely.
