When we went to a math’s revision class, she told us her motto was “fail to prepare, prepare to fail” - if you don’t bother revising, you have a high chance of failing.
Isaac Power stated “Revision is important... without revision you might forget things that will be on the test”. Khaled Ahmed said “I like revision, it’s really good, it helps me quite a bit”. James Wootton said “No comment”.
So, the moral is, revise plenty and good luck on your exams!
