Time wise it did get silly!! I ended up with 4M and 6D
I'm not sure it is possible to do from home - subjects such as PLCs will be impossible.
Yeah, PLC's is one of the subjects I found quite hard as I am not involved with them through work.
I must have been mad to go back to college for 4 years. Think you can top up the HNC to a HND by completing another year.
Where did you complete your HNC? Have you considered furthering your academic studies?
