Mathematical Grammar School has built a reputation as an elite school throughout its 45 years of existence, with significant world stage highlights at the end of 1980s and during the 1990s, which led to increased number of candidates applying every year. Eventually the number of applicants far outnumbered the number of available spaces. Paid classes were introduced in 1997 for students whose parents were willing and able to pay for their education. This practice has continued since, enabling the School to keep its high teaching standards through budget improvements. Basic fees are 10,000 euros per year.
