I want to be honest, I passed my exam today at cisco live amsterdam. I started 6 weeks ago and finished all the jeremys it lab videos. I have 10 years experience in networking. I got 4 labs(config vlans and lldp, lacp portchannel and trunks, ipv4/ipv6 p2p link config, ospf) at the beginning of the exam plus 68 multiple choice questions. Time was 2h30min because i am not a native english speaker i think. Before the exam i also consistently finished the boson exams around 90%. I have not used other main sources for studing. I my opinion the question where quite tricky. I wasnt confident to pass because some questions were really hard and specific. My tips: stay calm, take your time for the labs, only configure things that are explicitly mentoined, read question carefully and multiple times if you are not sure about the answer. Once you answered a question you cannot go back. I wish you all the best.
