Hacking to achieve XP points

So, my 6th grade students figured out how to "hack" duolingo by going to a "test out" section, turning their wifi connection off, and typing in any random thing. With wifi off, any answer is accepted. Then they turn back on their wifi to answer the last questions. At which time they gain all the XP points and all the levels are now completely done in gold. I have not found a way around this with them. Even logging out and back in keeps their progress. FRUSTRATING!!!!! I know they are only cheating themselves, but I would like to find a way to prevent this. Help????

You can't prevent them from doing it again, but you CAN reset the languages when they do test out of them. :) :)

One thing you can consider is giving them a paper and pen test on something they've already passed on Duolingo. Use that for the grading and give them zero points for that section of Duolingo?

Good idea Usagi!

Unfortunately, as you can see in this discussion, it's a behaviour known for more than 2 years (at least) by users and staff.

My personal guess for it to still be here is that Duo is in front of a dilemna:

  • let the system handling micro-cuts of the wifi connection by just accepting the answer in case the submission of it occurs while the wifi briefly went out.
    • Pro: "Protection" against unstable WIFI.
    • Con: Users can use this "protection" to cheat.
  • no having this "protection against unstable wifi".
    • Pro: Users can't use this "protection" to cheat.
    • Con: No "protection" against unstable wifi.

And I guess Duo finds less bad the 1st option: those who want to learn can do it even with unstable WIFI and those who don't want to learn... well they "play but don't learn".

There’s another option: delay going on to the next question until the answer can be checked.

    If I am using Chrome and my wifi gets interuppted during a lesson, the lesson proceeds as normal but when finished the XP is not saved. You also lose XP is you refresh the screen during a lesson.

    Yes, this bug described by the OP (in this 2 years old discussion) has been corrected by Duolingo months ago (around a year ago, if I remember well). So it's normal you're not experiencing this bug. ;)

        Some Smart students you have there :P I recommend you give them paper and pen test, as Usagiboy7 has said. Duolingo can also be a privilege. They can learn a language on Duolingo, or lose their privilege, and have to learn from textbooks. Think about that. As a teacher, you should be responsible for their learning.{@style=color : Teal}

        Very true ;)

        September 16, 2017

        Not that smart

        I often wonder how some people, including "admin" are able to get such incredible scores. I am a pretty studious over-achiever and on my best days I can possibly manage 450-650 but as soon as I get near the top of the leaderboard, "admin" or someone with literally incredible scores (for their streak) zooms past in no time. It's not the aim to be at the top of the leaderboard but if there is a more efficient way to do the modules, study and retain information I'd like to know about it. I hated in school when I was second or third when it was common knowledge numbers 1 and 2 had cheated.

        YES. A couple of times sb would get like 15K in ONE DAY!!!. I'd like to know how they figured out how to learn so much so fast. So I just don't care now. Don't even check. Duolingo, with an inability to talk to any of the other users, became just a little bit lonelier. Oh well, I'll make lots of friends when I go to Mexico and talk in Spanish. :)

        I spend one or two days a week of intensive Duolingo. That means a score of 1200 EXP on average. I average 300 EXP on any other day. That by itself is already worth 2100 EXP a week. This is all very doable. It takes about an hour or two to reach about 400 EXP. Drilling on an older skill can amount to 800 EXP a little over an hour. All it takes is time and effort.

        Leagues suck and this troll ( is a massive cheat. Duolingo needs to scrap this crap asap or at least not force you into a league when it's all a fraud anyway.

        July 13, 2019

        hacks are bad

        I recommend you tell your student to write the word Duolingo give and then also write down the translation verison of the given word on an notebook. Thats what my teacher does to my class. And its helpful.

        Doesn't work anymore

        March 9, 2019

        The bug has been fixed

        April 18, 2019

        No it hasn't. This fraud ( did 4,000 points in an hour. It obviously hasn't been fixed.
