Introduction
I am offering a voluntary second tutorial session on Thur 7th September 11 AM - Scenario room G10
This is a voluntary tutorial session and attendance is not compulsory. Notice of this tutorial will be also on the Moodle Course Announcements.
The tutorial will be an opportunity for students to ask any questions you may have about the content within the next 3 online lectures. Please feel free to post any questions or content you would like covered to Moodle.
Online Lectures
