John was very patient and professional on the delivery of the course. Involving the students kept us alert and it was very interesting to see tips and tricks to make the project scheduling less convoluted. It is much appreciated that John had asked us on which topics we are already comfortable with or may not require in order to spend more time on the topics which are new to us. -Project Intermediate Melbourne
Vincent - Project Intermediate, .
Great tips on background functions, thank you. Only suggestion from me is that it would have been a little easier if the instructions were slowed down slightly and directory places/names were used more clearly as we were going through worksheets - it's a little hard when you are trying to navigate between two screens on one monitor, but overall was a great training session. Thanks again! -Project Intermediate Melbourne
