This resource has been reviewed as being “very concise, with as many grammar and vocabulary tables as possible, as little explanation as possible”. It offers ten modules (ranging from Daily Routines, Travelling and Transport, In the Shop and Bank to Studies and Work), as well as an English-Latvian dictionary. Each module delves heavily into grammar concepts that learners are expected to memorize.
