Achievable vs Kaplan for the SIE
Two very different products, and the honest answer depends less on which is "better" than on whether you need to be taught the material or need to be tested on it.
We make a competing SIE product, so read this knowing that. We have tried to keep the comparison to checkable facts, and we say plainly at the end where each of them beats us.
Side by side
Facts checked on Achievable's and Kaplan's public sites in August 2026. Both change their pricing and packaging; confirm on their sites before buying.
| Achievable | Kaplan | |
|---|---|---|
| Price | $99 one time | $99+ depending on package |
| Access length | One year | 5 months, $49 to extend 5 more |
| Format | Self-study, adaptive review engine | Self-study up to live online classes |
| Textbook | Yes, plain-English, with audio narration | Yes, the License Exam Manual |
| Video | Yes | Yes, plus instructors at higher tiers |
| Practice exams | 35+ full-length | Structured exams, some single-attempt |
| Pass guarantee | Yes, conditional (see their terms) | Not advertised for the SIE when we checked |
| Best for | Self-directed learners on a budget | People who want to be taught live |
Choose Achievable if
You are self-directed, the price matters, and you would rather read and drill than sit in a class. At $99 for a year it is the better value of the two on paper, the access window is more forgiving than Kaplan's five months, and the adaptive review engine is a genuinely good implementation of spaced repetition rather than a marketing word. The conditional pass guarantee also puts some of the risk on them, which Kaplan does not do for the SIE.
Choose Kaplan if
You learn better with a person explaining things, or your firm is paying and has a relationship with Kaplan already, which many broker-dealers do. Kaplan is the institutional standard for a reason: the curriculum is mature, the License Exam Manual is thorough, and at the premium tiers you get live online classes and instructor support that no self-study product can match. If terms like accrued interest and tender offer are brand new to you and reading about them has not worked before, paying more for instruction is a rational trade.
The thing both of them cost you
Time. Both are full courses built around consuming material first and testing second. That is the correct order if the subject is new to you. It is the wrong order, and an expensive one, if you already have a finance background and mostly need to find out which specific things you do not know.
This is the most common way people overspend on SIE prep: buying a course to teach them material they largely have, when what they needed was volume of practice questions and an honest diagnostic.
Where we fit, and where we do not
Passline is not a course. There is no textbook and there are no videos: it is 1,600+ original practice questions where every answer choice gets its own explanation, unlimited full-length simulations, and diagnostics that separate what you know from what you guessed. $60 once, access until you pass, and a full refund if you do the work and still do not pass.
Where we lose: if you need the material taught to you from scratch, buy Achievable or Kaplan. We will not teach you what a debenture is. We will find out, relentlessly, whether you actually know.
Plenty of people use both: a course for the first pass through the material, then a question bank for the two weeks before the exam. That is a better use of $160 than either product alone at $99.
Head to head against each of them individually: Achievable vs Passline and Kaplan vs Passline. Or skip the reading and take ten questions to see which sections you would actually lose points on.
