Selecting a Pool for delegation

"Every year, millions of tons of plastic enter the oceans, of which the majority spills out from rivers. A portion of this plastic travels to ocean garbage patches, getting caught in a vortex of circulating currents. If no action is taken, the plastic will increasingly impact our ecosystems, health, and economies."

What learning materials will I get?

As a Memento student, you will be sent the worksheet you practice during the lesson. Each worksheet contains grammar, vocabulary and a short video by which you can practice your listening skills and see how language works in real-life situations. Additionally, homework is also included in your worksheets.

What happens in a class?

Once we know your level, you will have the option to choose whether you want to take group or individual classes. The teacher will welcome the students and begin teaching the lesson using the worksheet that will be emailed you after the class. Regarding the group lessons, you will have plenty of interaction with your teacher and peers during the lesson. Your teacher will be monitoring you and taking notes for the collective error correction to be as efficient and useful as possible.

Is Momento a language learning app?

We are an online English school with a unique and innovative teaching method.
