the students are great and being korean under korean standards the students do try and work
hard with the strenuous effort required for many more subjects taught compared to
regular schools

I'm not often treated to Korenglish, but I find it fascinating.

Over the years on this site many private schools in China have tried to repair the damage to their recruitment efforts made my unfavorable posts on this forum written by ex-FTs.

A routine tactic has been writing positive posts in the guise of non-existent happy current FTs at the school. This almost never works because few non-native students of English write very well. Even Chinese professors of English at universities have difficulty with various aspects of writing English, prepositions, articles, SV agreement, etc. Native English speakers who write poorly also have many errors but they are distinct from Chinglish. FTs reading the forum easily distinguish between genuine and bogus posts.

KISQ has also been unsuccessful with its charade, but at least they are exhibiting grammatical errors that are culturally fresh.

Kimchinglish?
