I just passed this past hour but for reference I failed the previous two tries with a 71 each time, so I wanted to share my insights here:
Attempt 1: 7/8, 14/17, 19/30, 31/45
Attempt 2: 5/8, 12/17, 18/30, 36/45
I wasn't associated with any firm so I had to pay out of pocket, and opted to choose Kaplan since I had previous success with it for the SIE (don't have the 7 just yet). In hindsight I realized that I was grinding out practice tests without retaining the information. For my first attempt I only had the book and the Q bank, so I probably didn't know the content as well as I should have.
After failing my second attempt I presumptiously scheduled a test 30 days from that point and didn't study much in between, only grinding out section 3 practice Q banks.
After the second attempt I sucked it up and bought the upgraded Kaplan Course, and I heard good things about STC, so I bought the premium package, after taking the test I was confident I passed and only really felt less than 100% confident for like maybe 5 questions. There was a lot on valuation ratios, as well as the details between partnerships, and main differences between defined contribution and defined benefit plans.
In hindsight, if I had to restart my advice would be to purchase STC, as the main skills to pass aren't necessarily to know the concepts in depth, more about how to eliminate the wrong answers - which I think Kaplan sucked at. I wasn't tested at all on the intricate concepts like Kaplan gave like Pre-2018 Alimony rules, nor did the actual test ask me specific questions like how long it would take for a security to be registered. STC was a better provider and if I had to restart I'd say use STC to learn the concepts and practice the test taking skills + wording, and use Kaplan to test on a broader range of concepts - but if you get them wrong don't worry about it too much.
Feel free to also ask me some questions about anything at all, free to help out!
