INTT 030 - Introduction to Trades

This course is designed to present the essential skills required for success in most (those that require Grade 10 as a prerequisite) of the Trades programs offered at Northern Lights College. The course consists of four modules: reading and comprehension for the Trades, Trades Math, Trades Science and Technical Drawing. Emphasis is on application of this material.
