Then you must work at an upscale school. Jeeeez!
She can get a real education in Thai for a lot less than that. Learning English as a Second Language in the USA is a couple hundred Dollars a semester, max! And Education prices there are crazy in the USA.
One subject! My AA, BA, & MS (plus a certification in Electronics) only cost me a 130k USD over 7 years!
If your institution, in Thailand, is changing 50k for a single one-year program, your work is a scam!
1 Year at Harvard University will cost about 50k USD for 1 year tuition.
Unless you are talking about 50k Baht.
