The training is insufficient to pass the CCES 156-535 exam. The book provided with this course only gives about 20% of what is actually covered in the exam. And then there is also a mistake in the book with regards to cplic print command. I would not recommend taking this course to pass the CCES exam. Rather use the CP online harmony deployment guide and R81 deployment guides. Then secondly, the instructor that provided the Singapore course was really not good. He didn't engage the audience and just rambled on. Also, just said to follow the instructions in the book and then he disappeared. At some point, he was presenting with no audio and didn't respond to us. Almost like a recording that didn't work correctly.
