This course was great, very informative, had Lionel as instructor and he was also very good.

Instructor was eager to assist but lacked subject matter expertise. Course time management was very poor. Content provided could have been delivered effectively in a one day course.

Reviewed by Inta N. 2012

   

Good Course, good trainer. All questions addressed equally and in a timely professional manner.

The course content was interesting; however, the instructor didn't have enough knowledge about Microsoft Sharepoint 2010 Development and wasn't able to answer questions without google search. In the future CTE needs to make sure the instructors have real on-hands experience and are highly trained in the technologies they are supposed be teaching.
