certain languages have 3 units each comprising 30 audio lessons roughly lasting between 25 and 30 minutes. If you complete the 3 units you may say that you've reached level A1 of the CEFR. If you want to move forward you might want to give a chance to the LanguagePod101 programmes.
this is a decent program to practice pronunciation and a bit of listening comprehension. this program is best used paired with something else. for example, you guys should check out the assimil series. its supposedly one of the best programs in europe for language learning. also look for the ultimate beginner intermediate series of books by living language. get those books, plus pimsleur, and watching movies/listening to music in your target language then you should be good to go. i happen to use all of those plus im taking university courses so im hoping to be fluent in no time.
