exams - load of crap !

Have been damn busy with the exams... ;( ....I sometimes wonder why these long written exams even exist still now !? why cant you replace it with simple objective type exams where each student's knowledge and intelligence are tested instead of testing the capacity of emptiness in your brain to where all these loads of crap theory and formulae are fed into by byhearting ? ! After all who is gonna use formulae from brain in future when you always have books to refer to . We need a change in this system !
