Forums IMPORTANT: PLEASE READ PhotoReading, Memory Optimizer activation

Hi everyone!
I have 2 question regarding the activation process:
1.Is there a time when the activation comes too late? I mean can I even activate something that I’ve photoread – lets say- a month ago?
2.I’m a student, so here is a PR-&-learning-for-a-test-question:
if you have to learn for a test do you photoread your book(s) a few times w/o activation or is it more efficient just to repeat the activating process?
I hope someone can help me with that...

1- I've heard once you do it "it's in there."
2- PR once and activate many times in 30 minute chunks using multiple passes and multiple mind probe questions and finally a mind map.
