I have been here for about 3 months and it took a long time for the instructors to warm up to me/seem to want to help. The program is currently in a bit of a restructure so I understand.
3 months in and I have to take a certification exam. I call the assessment center and the lady on the phone is extremely rude and very unhelpful, trying to deter me from scheduling an exam although it is a REQUIREMENT for my program to schedule the exams. Just due to this incident I really feel uncomfortable which is unfortunate because I have many more certifications I need to take. I have no idea who that lady is but she was not nice at all and honestly probably shouldn't be working at the assessment center when her job is to schedule assessments and she is telling me to not do so...
Overall the school is a good place, despite my 0 star experience with that staff member of the assessment center.
