Hardest ever exams ! Just not fair on kids

This new exam system has been totally wrong ! Who on earth changed it and decided this much pressure in our kids today is good for them ? Who thinks this much stress at a young age , is good for them ? . This has lead to so much stress for my child , her friends and kids and parents everywhere .
Parents are seeing their children change in personality , go from happy to unhappy children , being expected to pass these exams and thinking its the best way to start a careeer ( I dont think so ) I think this is leading too over stressed , upset kids and very hurtful for us as parents to see our children experience this .
I for one will not want to let this continue
