Indian Institute of Chinese & Korean Language offers courses in Korean and Chinese language at the basic level, intermediate and advance level. They only offer weekend classes that are held during the first half of the day and teach in small groups of 5 to 10 people. The basic level for Korean language is a six-month long certificate course that will commence in September, so we suggest that you get in touch with them to book a spot ASAP.
You might also want to attend one of their trial classes on weekends to help you make an informed decision.
