Before you smart people that love exams and end up getting 100% every exam start arguing, read my side of the argument.
Summarised points:
1) January exams have been removed - There are only June exams now. Giving students ONE shot at getting the grades they deserve is frustrating and stressful, people were given second chances before while they're only given one chance at their exams this time... Failure rates will probably rise by 50%
2) Exams prove nothing -The only thing they prove is that you know how to read a book and memorise, they don't prove that you're capable of thinking around problems and don't prove that you're ready for the real world, you also don't gain any experience from them.
3) Those doing BTEC courses and those doing A-Level courses have the same shot at getting into university - Completely unfair. BTECs are known to be MUCH easier than full A-Levels, yet top class universities accept students with BTECS for most courses/degrees.
4) You forget most of the stuff you've studied - Most students forget and never use most of the stuff they studied at A-Levels... Also, they practically recap everything you've studied at A-Levels in university (not all courses). This shows that exams aren't effective at all.
5) Physical exams and coursework are better alternatives - Physical exams show that you can apply knowledge and experience to gain real results, not numbers on a paper. Coursework proves that you are capable of completing projects by a deadline, which is most likely what you're going to be doing after graduation. You'll be taking part in projects, not sitting there writing exams.
6) Only a small amount of what you studied comes up in the exam - You study the whole syllabus only to realise that 1/4 of what you learnt comes up in the exam... Why do this? Would you ever tell a prospective civil engineer to learn to build houses then test him by telling him to install a window?
7) We've developed - School exams have been going on for many many years now and they have never proven anything. Thousands of students graduate from top class universities and its always the ones with experience that are hired to work. (Not for Medicine or related courses)... You should obviously have the knowledge, but a student with a 2:2 with heaps of experience will obviously get employed over a student with a 1st and barely any experience. Also, there are hundreds of thousands - millions of graduates who remain unemployed because they don't know how to fully apply their knowledge to real world scenarios.
8) Education develops, knowledge doesn't - Every year they tweak their education system, changing variables and fixing up numbers. The only thing we need is the CORE knowledge. 20 years down the line, the education I received would be completely useless and I would be relying on experience and core knowledge e.g. The basics of Mathematics and the basics of English to get me through. I would never use 80% of the theories and equations I've memorised.
All in All. The British Exam system is failing internationally.
