I took a one-week, intensive individual course and at the end of five days, I felt that I'd already made progress in comprehension, expression and grammar. The staff were friendly, welcoming and helpful. The housing situation was not as expected, due perhaps to a misunderstanding, but otherwise, I felt the program was well worth it. I've recommended OISE to my friends and one of them who attended earlier this year was very pleased with the results. Thank you OISE!
