Shuffle across the learning materials

To break down the memory paths in brain which are related to sequence of learning materials.

It is much more difficult to learn/remember when the all questions will be shuffled and not just in sequence of particular material.
My brain knows that the first topic is english verbs, followed by technical english etc. and it rely on it during remembering answers. In real live situation, it is very difficult to remember particular word because it is random access to memory.
