I've seen some posts saying how on duolingo the highest level you can get is A2. How is that possible? In most languages on here, they cover multiple tenses, grammar, and vocab. I would think when you finish you should be at about B1, possibly B2 if you really worked hard. Obviously duo will not get you fluent but it does a very good job, I don't understand why people say you'll only get to A2? I've learned so much and have had conversations with native speakers that understood me.
The levels are based quite heavily on your flexibility of that language and the situations you an apply it in not the amount of grammar you know, you need to know every tense just to get to A1 but to reach the higher levels you need to know about 8,000 words and be able to speak about many different subjects without preparing before hand or using a dictionary, Duolingo teach you only around 2,000 words and that includes all the different conjugations so realistically a lot less.
These levels are also based heavily off of listening and speaking of which Duolingo teaches you almost none.

Here's a grammar-based break-down of the CEFR levels: https://www.examenglish.com/CEFR/cefr_grammar.htm
A1 (for English in this case) requires present simple, present continuous, past simple, and imperatives. Future with "will" apparently doesn't show up until A2, and some of the more advanced tenses/moods/aspects don't show up until B2.
These levels are also based heavily off of listening [and speaking] of which Duolingo teaches you almost none.
I strongly want to advise to install Camilo's user script (for the web) "Duolingo tree enhancer" https://www.duolingo.com/comment/19654789/Userscript-Tree-Enhancer to auto-play L2 target language audio also on forward courses for right hand side translation answers, e.g EN-PT: Portuguese.
It can auto-play the L2 audio even for the longer sentences from multiple-choice, select a word excercises on the web.
This is an additional benefit which you do not get for forward courses on the Android mobile app!
It is not a big "listening" step on DuoLingo, but better a smaller one than none?! :-)
For reverse trees you can even hide the texts, so you can strongly focus on listening.
Yeah, I know what you originally meant with listening comprehension:
Hearing longer texts, person dialogs, and be able to answer multiple questions to it.
Just like TOEIC English tests are prepared...or those texts from BliuBliu...or any real language tests.
Duolingo has said that they 'wanted' to get people to B1 but as of yet it is definetly not, Duolingo only covers the basic foundation of a language nothing intermediate and allows you to move on to higher more self sufficient studies which is what will get you into the higher levels with a lot of work
