Don't rush! Take your time and do each and every exercise! Follow the textbook and complete each lesson after lesson, worksheet after worksheet. Be consistent! It's not how much you can do in one day. It's about how much you can do every week, 3 times a week.
Very important: Review every exercise! Reviewing and writing your own examples and sentences for each grammar and vocabulary topic is crucial.
When it comes to memorizing vocabulary: Our flashcard package will give you everything you need to keep you engaged and on track. Also, do the course again from the beginning a couple month later. It will make a difference!
