Yes, challenge problems for the IM sequence and other high-school courses, test-prep courses (SAT, ACT, etc.), and competition-math courses (AMC 8, 10, and 12) are either under development or on the roadmap. We don't have any estimated release dates that we can share yet, but the first out will be the SAT course, which we'll post more about as it gets closer to completion.

That is an interesting idea. However, given the immense amount of tooling, expertise, time, effort, and ultimately cost that goes into creating effective prerequisite and encompassing knowledge graphs and the courses that run on top of them, I'm skeptical that that would be possible in a way where we would have a reasonable expectation of a positive outcome.

@JuanPabloAbri13 @ninja_maths @justinvincent Yep! We've talked about that too. We'll get Streaks out first, then Groups, and then go from there. We have a lot of ideas, but it's usually better to release something relatively simple first and iterate there based on what we learn from our users.

@onesciemus Yep, we're really going to kick things into gear this year. Both in terms of features and capabilities as well as courses and content. There is a mountain of work to do, but we're about to bring it!! 😃

We're going to keep it simple. To maintain a streak all you have to do is complete a single task on that day, and it can even be a simple Review task with 4 XP. Think of us like the personal trainer you hired to help you get into shape. Our primary goal is just to get you to the gym. If we can do that, then we're 70% of the way there. After that, we'll do our best to motivate you to hit your daily goal. Yes, and I know this as well as anyone, some days will be better than others, but the key is to keep showing up!

Yeah, that's a good idea. Weirdly, I hadn't really thought about that, or at least not in years. But I like it, and we definitely need a way to elicit more commentary and feedback from students because the way it works now, we typically only hear about content errors, which while important and helpful, isn't great at gathering the kind of subject information we need to improve the content as rapidly as would otherwise be possible. So, thanks for the suggestion!

@sutherlandphys Wow, thank you!

@eulersconstanto @justinvincent Thanks! The blue circle indicates a streak freeze, however, we've moved on to using a snowflake icon instead. The dashed circle is meant to indicate a streak repair. But keep in mind that this was just our first shot at it. The concepts are still advancing.

@richseapear There's too much to explain in a comment, but I'll post another screen design or two later today to give a sense of what to expect.

@maw501 "contain" => "contrarian"

@martinbengtzen Like, I even messed up the second sentence of the previous comment, somehow not typing the final "up". A screw it.

@justinskycak could provide more detail on this, but the total XP required to complete a course can vary depending on your learning efficiency, so it's a moving target and just an estimate. If you miss a bunch of questions on a quiz, that will set you back for instance, or if you take time that will cause your estimated knowledge to degrade, which can trigger more review tasks, etc.

@carpdiem @_MathAcademy_ Thanks, Michael! We'll get this sorted out.
