Wesley Methodist School Kuala Lumpur was top school in Malaysia for SPM results in 2015 and 2017. It is a private school and in 2015 they took out national newspaper advertisements to congratulate their SPM students (GPS score of 1.13) and immediately got a written warning from Ministry of Education.

So when they repeated the feat in 2017 and got best SPM results in the whole country again, no more advertisements and in fact, if you look at the "official best SPM government school list for 2017" the top school is listed as Sekolah Tun Fatimah Johor with a GPS score of only 1.31, whereas the Wesley Methodist School GPS score for 2017 was 1.19

The lower the GPS (Gred Purata Sekolah) score, the better the school's SPM results are. However, Wesley Methodist school is now doing full IGCSE instead of SPM with their last batch of SPM students in 2018.
