钢琴等级1－10的背后代表着什么意思吗？水平的高低？程度的深浅？能力的强弱？准确来说，每考过一个等级，都意味着你已经完成了这一阶段的测验。
Do you know the meaning behind piano grade 1-10? What's the level? How deep is it? The strength of ability? To be exact, every grade means that you have completed this stage of the test.
所谓考级，是由有权威的专家，对学生的学习状况和对老师的教授情况以及学生自身所达到的程度，给予相对客观、并且准确的鉴定与评价，学生通过测验，便会获得相应等级的证书，以证明其达到了这个等级的程度和能力。
The so-called grading examination is a relatively objective and accurate appraisal and evaluation given by authoritative experts to the students' learning situation, the teachers' teaching situation and the students' own level. If the students pass the test, they will get the corresponding certificate to prove that they have reached the level and ability.
