No. PRing is about "photographing" pages, but those "pictures" go into sunconsciousness where they're analysed and combined with your conscious and subconscious knowledge/memories. In order to bring that knowledge into consciousness you have to do some activation.
There is spontaneous activation - something triggers part of "picture" and you know although you're not sure how. That's the most amazing part. However, you can not rely on that. So, you have to activate "manualy". That takes time, depending on material and your attitude. If relaxed, subconscious can send info to conscioous so you gain knowledge/understanding quickly, otherwise you approach to it in traditional manner and that's what we're all running away from. 
PR requires that you use it. The more you use it the better you get. At the beginning PRing should enable you to learn and fully comprehend material in 1/3 of the time it would normally take you. NOT in 5 minutes. 
Hope this helps a bit.
