Good point. SEE the difference. Graph a chart or allocate the same variables of time spent towards your studies with and without PR.
Stay with it even when it seems hopeless. Winners never quit, quietters never win. If you give up soo soon, then you'll just fall like rest of people who switch to speedreading or just give up.
Forum is for help, most people do a last remark on how they failed and quits. I'd stay away from a while to see some change in reading or not reading the forums. Definity spend more time so PR can glue to your needs.
Again, listen to AlexK. He is more knowledgable and wise than rest of us beginners.
