A quick note to say thanks very much for the information I garnered at the course. The training was very informative and practical; the handout material contains a lot of information that will be helpful in future.

By choice, and as I didn't want to disturb the man next to me, I didn't ask to many questions of the instructor. I realize that taking the same course at the same time would have been ideal, but I understand why we were put in the same space. I had a few computer glitches which shuffled the course material around a bit which I eventually found a work around for. A lot of material for one day and I did find myself paying attention to the clock to make sure I finished at a reasonable time.

I thought that the course content was excellent, it covered a wide variety of new features in 2010 at a sufficeint level of detail. The video instructor was also very diliegent about highlighting the various ribbon features and showing alternate methods of completing a task. This teaching method may not be for everyone, but I enjoyed the ability to learn at my own pace, without being slowed down by questions that were not relevant to me. It would be nice to have better control over the video streaming in order to skip over/ahead on topics that are familiar to the user.

Found that the advance training was where my level was at already on most items (wishing there was a super advanced training). Found the ‘instructor’ not to be conversant on the program I was being trained on (probably the same level as I was) which was frustrating. He did ask other personnel which did have more knowledge but did not give me a clear answer (said it was part of the limits of the program and what I was looking for was very customized, duh this is why I took the advanced) He was willing to go over the ideas of tables and relationships with me which was not covered in the course, which I was thankful for. The course did delivered though what it had said it would and it was good to get reinforcement on what I had learned on my own, that I was on the right track.

Hi, There was one problem with the flow. I'm not completely sure as to how best to describe it but basically, it didn't flow from one module to the next. Specifically, if I was in a particular module (say the introduction or first sub-module) and it completed, I was not automatically taken to the next sub-module within the overall module (a module being a section of the course). Feel free to give me a call to discuss at 416-686-3141.

The first hour of the course was difficult due to the noisy environment. There were 3 separate software platforms being mentored by 2 instructors simultaneously. As each required unique start up instructions, it was very difficult to concentrate on the video teaching for my session in spite of the headphones as there was a significant amount of background noise. I suggest that future sessions that are mentored rather than led be done as dedicated sessions (i.e. only 1 software platform being taught at a time) to minimize the impact of this situation. Additionally, the 2 instructors had side conversations that had nothing to do with teaching the sessions and needed to be asked not to do this as I found it was hindering my ability to listen to the video lesson. Unwilling to crank the volume on the headset, I could hear them clearly over the top of the lesson I was listening to.

While the instructor had a basic understanding of Project 2010, he did not have "advanced" knowledge which was the level of the course. He had not really used the software in "real life" so didn't have any context. Whenever I had questions, he looked for answers from microsoft.com (I could have done the same). I was hoping the instructor would provided added knowledge to what I was learning from the videos.

There really is not enough time in one day to do all the exersizes in the training manual, watch all the videos, take the quizzes, and discuss specifc issues with the instructor. I would suggest improving the video intruction to actual take you through some of the exersizes rather than leaving you to do it on your own, because you really only learn by doing.

The only somewhat critical comment I have is that it can be difficult to concentrate when the mentor is explaining to another student. In a small classroom setting, I guess that is just a reality of mentor-assisted training.
