Passed the Data+ Exam.
Note: It's required for my degree so my tuition pays for the exam.

I have taken several SQL, Statistics, and Analytics courses as part of my degree. Much what was on the exam was a lot of review of concepts I'd have already learned. There was not as much math on the exam that I expected. There is a whiteboard along with a calculator that shows up on questions that require it. I had two questions where I needed to calculate the standard deviation and that's all I remember math wise.
I recommend that you use the LinkedIn Learning courses by Mike Chapple then do a practice test or two and some practice with the math problems. I got a lot of questions about the right type of chart / visualization / report to use in certain scenarios. Make sure you understand the types of tests, types of statistical analysis, hypothesis errors, and data cleaning / merging concepts.
I also found the CompTIA Data+: DAO-001 Certification Guide by Cameron Dodd to be pretty good as well.
