English classes for the grown ups usually focus on a single aspect of communication, mostly spoken. It is rare to see a class for written English. And it is all the more rare to see a class for both.
S K Academy has organized such a class. The class lasts for 25 days, 5 hours each day. It is an intensive training in all the basic aspects of English. The classes are conducted only at Trivandrum in India. The course fee is 8000 INR for a person but only 5000 INR for the first ten entrants.
The course makes use of a patented system which was twenty years in the making. Five facilitators who have good track records will handle the classes.
