On 15 March 2012, he broke the mental calculation world record of completing ten tasks to "divide a 10-digit number by a 5-digit number" in a record time of 5:45 minutes without any errors. These tasks were constructed by a program provided by Dr Ralf Laue, author of the Book of Alternative Records and Chairman of Mental Calculation World Cup, such that there are no remainders. The previous record holder was Willem Bouman from the Netherlands with a time of 6:07 minutes. This world record was  accepted at Guinness World Records, Limca Book of World Records and UK's Book of Alternative Records.
