6. Practical's
For all practical exercises will require students to follow the T104 workshop good working practices
Evidence of practical's must be submitted to Your Space
Assignment responses must be submitted to Turnitin
Video/photographic evidence must be edited to show concise, clear evidence and reduce file size
A professional standard of presentation for all submitted work is expected without spelling or grammatical errors.
Timely completion is expected and errors must be corrected
