Education system based on useful knowledge
The current education system forces students to waste time learning useless things. Also, the system is not flexible: students cannot complete easy courses quickly. Instead, students are forced to waste time doing easy homework. I find that students' time is precious and should be spent carefully.
Current proposals for change of education system on the internet focus on 'learning less' or 'becoming more creative' or 'being all-rounded'. I am not disagreeing that students should be all-rounded. Rather, the phrase 'all-rounded' is misused. Systems that claim to make students all-rounded accomplish the goal in such an ineffective way. Instead of learning entire humanities courses, science students should be allowed to simply glance through and understand basic history, for example, with no need to memorize entire textbooks. After all, 5 years later all that history isn't going to help them become 'all-rounded', what helps them is those few pages of understanding they have, not the thick books full of stuff to memorize.
While science students benefit from learning to write, there is no need for them to spend years learning history or english, rather they should have courses such as 'writing for science people' or 'a course for science people on how to analyse stuff like the history guys do, with examples from history so that you can and will actually apply the stuff you learn to become a better scientist.
