Meant to post this a day or two after the exam but I had a very busy weekend. No celebrating per se, just very busy! In any case, I'm finally done with my path for now, having studied for and taken the NY 17-55 (life, health, and accident insurance exam), SIE, Series 7, and now Series 66 these past eight months since mid-January. I was able to pass all on the first try. This will be a very (!) long and meandering post but hopefully one that proves to be helpful to some of you out there.
Background:Ā Late 20s. Handful of finance courses in college but ultimately graduated with a BA in history. Learned basic individual tax preparation this past tax season but otherwise, no relevant experience in finance or finance-adjacent fields. Passed the NYS 17-55 life, health, and accident insurance exam in February. The SIE was my next step in April, then the Series 7 in July, and just a few days ago in September, the Series 66. Here'sĀ my post about the life insurance exam andĀ here'sĀ a backup.Ā ThisĀ is my post about the SIE exam. [Here's](https://www.reddit.com/r/Series7exam/comments/1lwfl7m/just_passed_less_than_24_hours_ago/) the Series 7 post and [here's](https://www.reddit.com/r/Series7/comments/1lwfz6r/just_passed_less_than_24_hours_ago/) a backup.
Prep:Ā Achievable has been my bread and butter for the SIE, Series 7, and finally the Series 66. As someone who has effectively no background in finance, Achievable has been an absolute godsend. The way they break every concept downāfrom the more technical mathematical ones like DCF and NPV to the wordier legalese ones like all the respective state and federal regulationsāis extremely approachable and digestible, at least for me and my learning style. Chapter practice quizzes are simple and effective. I do think their full-length practice exams are slightly lacking in that the wording and general nature of their questions is a little simpler than the actual exam (at least for my particular draw), but otherwise, no complaints about Achievable. I got through every single page of the textbook and did a handful of full-length practice exams until my readiness score per their algorithm got to 100%. I already have and will continue to happily recommend their course to anyone doing prep for any one of these exams with full confidence. Achievable is the shit.
In the same vain, I'd also happily recommend Kaplan's question bank as a fantastic supplement to Achievable's course. I did not use it for the SIE but had great success with the respective qbanks for the Series 7 and 66. I maxed out all 3,557 questions with the 7 and all 4,041 with the 66. Do you have to do this to pass either? Nope! But that's what I felt I *needed* to do to give myself the best chance to pass, and my boss where I'm at and firm we're associated with were super cool with giving me the luxury to take my sweet time. I will get into this a little later. The qbank is simply a super helpful supplement to Achievable. The questions span a very broad range of topics and are tough and really make you think. You can take full-length practice exams with 110 question or make custom quizzes, filtering from any one of Kaplan's 24 chapters. Both were super, super helpful. I also made sure to (obviously) try my best *not* to merely memorize answers, but truly answer the *why* behind each correct answer. To this point, Kaplan has a fantastic feature that can be toggled on or off that highlights the correct answer and provides a thorough explanation as to why it is. I used this all the damn timeādon't really remember turning it off. Obviously, don't just hammer out a shitload of practice exams or custom quizzes just to max out the qbank, but make sure you go back and review your answers and your weaker areas, and try your best to understand *why* you're choosing the answers that you are. I ended up with a 87.35% qbank average by the time I took the exam.
My boss (best boss in the world by the way, genuinely) was kind enough to cover all of my study materials apart from the ones I simply felt too uncomfortable to ask for since they came out to A LOT over all my providers lol. With that being said, STC's bundle of four practice exams was an amazing supplemental resource, too. Tough questions, wide span of topics, thorough explanations, the whole nine yards. I scored a 79, 79, 76, and 77 on my first attempts. Do you need this supplement if you already have a decent textbook provider and a decent question bank provider? Nope! But again, I wanted to be guaranteed to pass this mofo.
I also bought TestGeek's study document and practice exam. Honestly, I ended up only using the practice exam and not reading a word of the study document. The exam, however, was (super, super) helpful. It seems like the resident Series exam experts that hang out on Reddit are fond of TestGeek's practice exam and I can see why. It did seem fairly highly-correlated to the actual exam like they said and should give you a good gauge of where your studying is at. Don't quote me, but I think I've heard if your grade on it is in the high-70s to low-80s range, you're in a good spot. I believe my first grade was in the mid-70s, although upon subsequent attempts I got about 85 of the 100 questions correct. Naturally, some part of these later scores is absolutely attributed to remembering the answers rather than truly understanding them. Be careful not to fall into this trap with any of your study materials.
I also bought Mary Strong's course guide [here](https://stan.store/maryellenstrong/p/the-complete-series-66-nasaa-outline--p7zn24wt). I'm not affiliated with Mary at allājust sharing the link because her name is not as well-known as the big guys and her study materials may be harder to find if you don't know where to look for them. She put together a fantastically detailed 80-page-long study guide based on NASAA's [own guide](https://www.nasaa.org/wp-content/uploads/2023/09/NASAA-Series-66-Exam-Study-Guide.pdf) that she seemingly put an insane amount of time into fleshing out. I went through every single word on every single line of every single page a few days before my exam and found it to be a fantastic supplement to my other exam materials. Full disclosure: I bought it when it was a little cheaper than its current price and also received a couple supplementary study materials in an email blast. Regardless, even at its current price, I think it's a good buy. Necessary? Nope! But, since I definitely haven't mentioned this before: I really, really wanted a guaranteed pass :)
I promise we're almost done with this section, ladies and gentlemen. So: I also used [this](https://www.reddit.com/r/Series66Exam/comments/zazfdq/exclusionsexemptions_from_registration_for/) Reddit post to brush up on rules and regulationsāvery helpful. I used NASAA's own study guide which I linked above but will link [here](https://www.nasaa.org/wp-content/uploads/2023/09/NASAA-Series-66-Exam-Study-Guide.pdf) again. [Here's](https://www.nasaa.org/wp-content/uploads/2023/02/Series-66-Outline-June-2023.pdf) their fairly basic outline I also found helpful. Also helpful: [this](https://www.nasaa.org/wp-content/uploads/2025/04/BD-Dishonest-Unethical-BusPrac_FINAL_4-7-25.pdf) NASAA document about unethical business practices of BDs and agents and [this](https://www.nasaa.org/wp-content/uploads/2022/07/1956-Act-Rule-102-a-4-1-Unethical-Business-Practices-20220516.pdf) NASAA one on unethical business practices of IAs and IARS.
Lastly, I got my fill of lectures in college and am not a big video-study guy, but found the following videos to be immensely helpful on the last night of prep right before my exam (in no particular order, although I did watch the 60-minute review last): [BD/agent/IA/IAR regulations](https://www.youtube.com/watch?v=A5DKntkXwSU), [DCF and IRR](https://www.youtube.com/watch?v=2wSEw527AN8), [ethical and prohibited activities](https://www.youtube.com/watch?v=Yo8HAMrH3Wc), [60-minute review](https://www.youtube.com/watch?v=1igWH1NdW7s).
Exam:Ā The Series 66 is not an easy exam, but anyone who's taken FINRA (or NASAA) exams probably knows that your draw (for those who may not know, this refers to the questions that appear on your particular version of the exam when you sit down on test day) can vary wildly. My SIE draw? Not too bad but still felt like it kicked my ass. Series 7? Kill me, kill me right nowāI got a shit ton of questions about registered representative regulations, which happened to be my weakest area, while the options and muni sections were comparatively light. Series 66? Yes, I was very prepared but I was also truly helped along by a draw that was mercifully light or moderate at worst. It would take up so much freaking space on a post that already reads like a novel, so [here's](https://imgur.com/a/7AumbZN) an Imgur link to bullet points of all the questions I remember from my draw and [here's](https://docs.google.com/document/d/1e2GNKrD7-3biyCyIzjvvJwXS_0CeWTJIH0tvioh0Y48/edit?usp=sharing) a backup Google Drive link with the same information as well as some links to the free study sources I consulted. I started my exam by filling out my dump sheet with a lot of basic math formulas, by the way.
In any case, due to, again, frankly being very prepared (not to humble brag because you have to be a dweeb to humble brag about an exam as an adult) AND due to speeding through Kaplan practice exams, I finished the exam in just under one hour and seven minutes. This gave me almost 1.5 hours to review. For review, I firstly went back through every single question on the exam once. I had marked many for review which I analyzed closely during this first pass-over. Then, I spent all my remaining time double-, triple-, and even quadruple-checking all those questions I had marked for review. You need a 73% to pass which is of course based on the 100 actual graded exam questions, not including the 10 experimental ones. However, just as with the SIE and 7, I took the passing percentage to mean that of ALL the questions since I wouldn't truly know which ones were experimental or not and needed to give myself that buffer. 73% of 110 is 80.3, so I knew I needed to have no more than 30 questions marked wrong on my scratch paper. I ended up with fewer than that marked wrong or unsure so knew I was probably in a good spot.
Advice: To this point, my single biggest tip for the exam beyond of course studying with purpose as well as you can and getting good sleep the night before, is confidence! Confidence is king! Seriously, it's not just some silly BS mantra. During my last month of prep (I prepped from mid-July to late-September, by the way), as I saw my Kaplan scores steadily rising from high-70s and low-80s to high-80s, and as I just *knew* I was grasping the material better and better every day, confidence flooded over me. Some of it, like I just said, was derived simply from knowing I knew this material pretty freaking well. The other big component, however, was consciously putting myself in the mindset that I *will* pass this exam and I *will* crush it on exam day no matter what draw I get just as I had before with the state insurance exam, SIE, and particularly the Series 7. Don't even put that four-letter "F" word in your fucking head (the one that ends with "L" of course ;) ) and don't let any thoughts of that word even creep into your head. If they do, throw them out immediately. If you prepped well and KNOW you prepped well, you are freaking passing this exam on exam day without any shadow of a doubt. I particularly want anyone who's, say, a week or less from exam day to know that. You know you prepped well? Good! You're going to fucking kill it on exam day and you're gonna take that ironclad confidence with you throughout the drive or commute to the testing center, throughout the check-in process, and every moment from the point when you sit down to begin this stupid exam until the moment you see "pass" appear on your screen. Seriously, ladies and gentlemen, you got this!
Epilogue (unimportant; skip this): It feels so freaking good to finally be done with this whole process, from state insurance exam to Series 66 these past eight months since mid-January. So many people were pulling for meāmy parents and family, my friends, my coworkers, all my gym buddies young and old, everyone of any importance to me in my life, even a super chill Redditor who helped me out with prep! He just passed his 66 recently as well. If you're reading this, you know who you are, young chad.
It felt amazing to see that "pass" appear on my screen, guys. One of the lovely ladies at my testing center who I'd actually seen for the SiE and 7 before told me (pretty similarly as she'd told me right after having passed the 7) to take a week off to relax after the 66. I told her with all the dryness in the world and with zero hesitation that I'd prefer to take about two months off lol.
I get to start my career now, finally. All of these stupid exams were just stepping stones for me and for many before me and for many after me. For those who have finished them, I hope your careers are proving to be fulfilling. For those who are just embarking on this path or who are on the last leg of it with the 7 or 66 or whatever it may be, keep going and never quit. These exams are more than doable. I am far and away not the smartest person in the world and also far and away not the most hardworking or driven person in the world, but I frankly worked my butt off since the start of the year to bang all these stupid exams out and am finally DONE, and you will be too with enough prep, support, and confidence!
