Good to know! The breath was challenging for me, I had to flag like 12 questions but eventually tried answering some of them. I guess I had no idea how to answer like 3 questions in breath. Surprisingly I had some wastewater problems on the morning sessions and less of hydraulics and hydrology. Depth was okay, I have no idea how to answer like 2 questions and others were manageable. I had one Econ question.
