The staff exhibits extreme efforts to help students and are very friendly. The course I’m taking is taught by Ernest Mashingaidze. He is very informative and willing to answer any questions. There are no bad questions. I feel that this course will prepare me for a number of jobs in the field. I would highly recommend this school to anyone.
