its crazy...
after doing 100% of world, everything else just feels so smooth..
Its a very sophisticated approach those World people are doing. They write questions where you REALLY have to know something to get it right..
if you know it "so so" it aint gonna cut it, you will get it wrong. The question writers know exactly what they are doing. Its a lot like weight training. Doing pushups with a backpack full of weights its grueling, cruel and unusual but you do them without the weights its like a nice soft walk in the park.
I need to get back to the gym..
