Social section/Feedback
There is a section in Busuu where you can meet people who are learning your language and they can provide feedback for your speaking and writing. This is included in the premium version of Busuu but you can make friends with people in the free version. Feedback is so important to check if you are speaking correctly.
The Problems of Busuu
Dynamic Speaking Practice
Speaking practice is the most important part of learning a language in my opinion and you don’t get this with Busuu. In fact, most online platforms do not offer speaking practice for free because English teachers generally need to earn money. Cambly and Italki are great examples of websites that you can speak English and have a real conversation.
Grammar is Premium
Most of the grammar lessons are premium so you need to pay for them. In fact, most of the lessons I think are the most valuable are premium (Video, Listening). The good news is that you can try the lessons and see if you like them and then decide if you have enough money.
Is Busuu worth it? Is it good?
Yes, Busuu is a great way to learn English. There is a study that showed that 84% of people improved their language skills with Busuu and with 20 hours of study you can learn the same amount as a college semester. Impressive! Busuu is best for beginners.
I think Busuu premium is worth the money but you could also take classes with Cambly if you specifically need help with Speaking/Listening skills or Espresso English if you need to fix a specific problem. You can have a look at the Espresso English courses here.
