[5/5] Great!

I kind of hated khan academy at times, but it is very helpful to me because it finds my level and makes things simpler. It has drawing stuff so I don’t need actual paper, and a video to show how it’s done. Thanks Khan academy! Also I find it satisfying when I move to another level.

[5/5] Redeeming my old education

I am going back to take Algebra for fun, but also to help my own kids. It would have been amazing to have had this resource available when I was taking it for the first time. I am so appreciative of the thorough and clear teaching, along with the interface, usability, and motivation-enhancing setup. Thank you!

[5/5] Great app, learned all of algebra 2

I was behind a year in math and I wanted to take the ACT early into my junior year. So I tried Khan Academy and I was pleasantly surprised by the helpful format and style of reviewing the material. Great app that definitely helped me and would 100% recommend

[3/5] Used to be great

It took me a while to utilize Quizlet, and when I tried it for the first time, it was a game changer. The study feature was my lifeline. Without it, I don’t think I would have gotten such a high grade in my college course. A few months later, I needed it again for a different class, but now I have to PAY to use the best feature on here?? Along with that, the organization of the study sets I want to use is extremely confusing. Very disappointed in what it has become.

[1/5] New updates after hack

After the hacks the app still does not work properly. The new UI continually changes back to the old one and erases everything in the to-do tab so none of the recent due dates for assignments appear at all. Logins also have been super buggy for some reason and give error messages. Used to be great, now absolutely trashed

[3/5] Mostly does the job

This app has some dumb limits to be fixed. Sometimes the class posts a slideshow in PDF format. The text is too small to view in portrait mode so when I switch it to landscape mode, the whole PDF disappears.

[4/5] Pls read And developers, pls respond!

Ok so i like the app and i like how u can now get ur old streak back but i dont like this energy stuff like i cant even finish a unit of chess. Also i was suggesting that duolingo should have like a chat or smthin so that we can chat with our friends or smthin like that. Anyways is overall a pretty good app. But im really complaining bout this energy stuff cause idk why we even need it like can we go back to the hearts!? AND PLS. CONSIDER THIS CHAT THING thanks and have a nice day!

[1/5] Forcing You to Pay

At first Duolingo used the heart system, which allowed me to do 5-6 lessons a day without paying. However, with the energy update, I’m hard capped at most 3 lessons a day, and the update is forcing you to pay to learn. Would prefer any other free site than this.

[2/5] Good but needs a lot of improvements

So many useless words and you have to know them to pass the level. Options for review are terrible. They keep reviewing the same words, most of them are not important, but they skip all the important ones. There is no good way to review what you want to. In new lessons you only focus on mostly new words. Doesn’t incorporate previous lesson words. There is one “barbell” area but it still goes over words from way back that are already solid. Really poor in this area. Speech recognition is very bad. In some places I can literally speak jibberish and it says correct. In other places (flash cards) you can say the word exactly over and over and you will never pass. Support for learning writing is also very poor. You write one character over and over during an exercise and then never review it again. Impossible to learn this way.
