I am a Kumon student currently doing level N and progressing to the last level O, in maths. I can say that Kumon did help me in the early levels and years when I was in primary school, where the only hard things were division and fractions here and there. Kumon really falls out when you go to advanced levels like I or M. Kumon's main method of getting students to learn is through brute force. They bombard you with many variations on a single question or concept, and expect you to learn and use it correctly. This is useful if you are very bad at mathematics, and can't properly divide large numbers. Kumon helps you with constantly giving questions based on a single formula/concept, which will help you do improve over time. But the pros basically end there. Brute force really isn't a practical way to 'teach' students at a higher level. For example, you wouldn't expect a student to solve Maxima and Minima problems by just showing them basic formulas and principles and letting them fend for themselves. I have personally experienced this myself, when I just couldnt solve a problem at level K and all the instructors at my centre could not as well. This probably gives you a perspective on how hard the questions Kumon gives to teenagers-children which the franchise claims the children will be able to solve with relative ease. Kumon also has this brilliant idea of charging an exorbitant amount of money just to hand you paper worksheets with maths problems on them. Where I study Kumon, there are instructors who mark your work for you and teach you so the cost is partly justifiable, but I know for a fact that there are some centres who tell parents to mark their own child's work! Kumon really suffers when it comes to school work. My mom has always questioned why I never excelled in my school maths exams when I was 2 years ahead of my school level in kumon. The thing is, Kumon doesn't really follow any syllabus. Yes, you would know how to solve simultaneous equations easily but would you know that you were supposed to apply this method when a simultaneous equation is changed into a word question? Probably not. I have encountered this multiple times in my maths exams, where I was really good at solving unknowns for equations in Kumon but I didn't understand the word version in school. Kumon is basically pure maths but on an easier level. Pure maths doesn't really take into account real world usage of maths. A question in a Kumon worksheet would follow something along the lines of : Using the Quadratic Formula shown above, solve the following questions. 1)Solve 6x2-7x-3=0 Answer : 7 However, a question on a school test utilising the exact same formula would sound like : 1)A garden measuring 12 meters by 16 meters is to have a pedestrian pathway installed all around it, increasing the total area to 285 square meters. What will be the width of the pathway? Answer : 1.5 metres. Tell me, which question would be easier to solve? Would you even know that the second question uses the Quadratic Formula? Do you even know what the Quadratic Formula is? Well, I had to learn this when I was just 13 or 14. I am now 15. These flaws of Kumon are why I think parents should not let their children continue long-term with the company. Its really great to let him be enrolled for a year to two to get an advantage, but its honestly suffering for the child. The child must complete a worksheet a day (with varying numbers of pages, level A-D would have a set 5-10 pages to complete which are double sided, meaning up to 20 pages of questions a day), within the set time limit usually an hour, with no breaks even on holidays. Kumon may require you to go to the centre every week even though its a holiday or its the year end holidays. I have been in the programme since 2012 and I have probably done more than 25,000 pages, with an average of 6 pages every day since I started without fail every day. If this isn't killing your child and robbing his/her freedom, I dont know what is. Again, do not ignore Kumon completely. Send your child when he/she is young and get them to learn the basics, then pull them out once they reach the levels of F or G. School takes over at that point. Thank you for reading my personal 6 years and counting of experience with the company.
