All the classes are useful as they always include hands on. There is always a lot of content and the presentations are very good. I like the way the certification is structured and the certification itself is very complete. I think the price is a bit on the high side. The certification is very expensive and so are the classes. I wish it was more affordable. I would definitely do it. The cost is worth it and the certification is very good. To earn the certification you have to do a lot of exercises and write reports. And there are so many different classes that you get to choose from and it's not too difficult to pick the ones that you will benefit from. I have been doing it for almost a year now and it has been very useful. I have learned a lot and it has helped me in my job.
