  5. Is there a way to predict theā€¦


Is there a way to predict the review burden of moving quickly?

I've been moving through the German tree at the rate of 2-3 subjects per day. (2-3 of the circles, which may contain 3-4 lessons).

So far, so good. I've had 2-3 skills to review each day, and it's going well. But....if I keep up this pace, will my review burden start to increase quite a bit? I don't want to overwhelm my future self.

I'm about to pass the 3rd checkpoint, so that makes: 28 circles complete, by the end of today.

Some context:

  • I'm doing Pimsleur German at the same time. So I already know much of the tree, especially the grammar. (I'm finding Pimsleur + Duolingo a great complement to each other. I can go faster in each as a result).
  • I'm going to Germany in a bit less than a month, so I'm trying to go at a very rapid pace to hit the ground running

But again, don't want to overwhelm myself. For the past bit it's been good, but I've only started accelerating the past five days or so. Am wondering if there is a way to predict how much review I'll have later on.

There's not a way to predict it as far as I know, but you don't actually need to review the circles to get them back up to gold, it's just recommended. Personally, I prefer to move more slowly through the skills and make sure I have a good solid foundation in all the previous lessons before I continue to the next one.


Yeah, I'd normally progress much more slowly, but....deadline. I'm also finding that doing Duolingo is letting me do Pimsleur faster than normal. (And Pimsleur is letting me do Duolingo faster than normal, a virtuous circle).

But, since I'm moving quickly I'm taking extra care to strengthen my foundation by reviewing the new skills. I figure if they're not gold, and I'm moving fast then I'm probably not learning. As it is I seem to be retaining.


Oh fun what's your deadline? I just do languages as a hobby XD

But yeah, using multiple methods for learning a language is way more effective than just one =)


Not really. :-(

As far as I know:

I think that the closest a userscript comes is to show you the current strength of the skill - if you know how to install a userscript (GreaseMonkey for Firefox or TamperMonkey for Chrome), and if it's still working with the most recent changes to the website, you might try using the "Duolingo skill strength" userscript. There are links to it some way down this page: http://duolingo.wikia.com/wiki/Duolingo_Userscripts

(I haven't used the script.)

But yes, the review burden is likely to increase. On the bright side, so long as you get things right, Duolingo gradually increases the length of time before a skill needs review.

Duolingo learns how well you know each skill based on the mistakes you make and the number of times you look at hints (and perhaps a few other things which we sometimes make guesses at), and so generates a review time (well, not even that, rather: a calculated decay rate, that eventually puts the skill strength low enough to need revision) based on the individual skill strength for each skill.

So, unless someone writes a userscript (or staff write a useful little piece of code) which projects how long it will be - based on current skill strength and current skill decay rate - before the skill reaches a certain strength level, there isn't any (easy) way to tell.

Personally, I tend to work to a set amount of revision per new lesson, so I always know how much revision I will be doing. I have found twice as much revision as new material is generally a good mix for me.


I've been doing approximately 1 skill and 2-3 strengthening exercises per day and I passed the second to last checkpoint before any skills stopped being golden. Since suddenly around 15 skills stopped being golden all at once, it seems I was in the A/B test in the group which needed less strengthening, but even since then maybe 2-3 skills per day need strengthening, so I guess that should be the limit if you strengthen them regularly and not allow them to lose more than 1 bar.
