Passed COMPTIA Sec+
I gave the exam at home online, you can't mumble or move even an inch or you get a warning. I faced a problem loading the PBQs and it took them 10 mins to give me a call. And no, you don't get those 10 mins back when the exam is restarted. They said it is giving them a problem on MACs. So I would definitely recommend use a windows machine or going to the test center to give the exam.
As far as the exam is concerned, I had 84 MCQs and 4 PBQs. For preparing, I used Prof Messer videos & practice exams, watched all of his study group videos on youtube, Jason Dion's practice exams & Darril Gibson's GCGA book. My practice exam scores were 86,88 in Messer's, 83 in the first 5 test and 88 in the last Dion test. And 88 in Darril Gibson's test. The practice exams are more difficult than the real exam but those exams help you understand so many concepts.
I would suggest have a basic understanding of all the exam objectives & all the topics from the abbreviations list which are missing in the exam objectives. It is an easy exam!
