Foolishly, they believe that they are testing us on how much we have learnt, but this is not the case; they instead test us on the capacity of our memory. To say the least, it is not a fair system. Perhaps they should revise.
We each have dreams we aspire towards, we each desperately hope that we may achieve them; whole cups filled with little rolled up pieces of paper, upon each one, a hope penned in the neatest of handwriting, then oh so carefully rolled up into a scroll and tied closed with string. We pray to attain what is written on those tiny scrolls, but the truth is, life has a way of putting us down.
So, we go in, we write all that we can possibly remember, all that we tried to cram into our overstuffed brains, and hope for the best. The reality is, no one cares about what you learnt, what you took from your lessons. They just want to see what you remember.
The saddest thing is, at the end of it all, you will forget, purposefully, everything you tried to remember.
