You will start with a so called starttest to see what you already know about the 'Present Simple' and 'Present Continuous'. Once you have made the test, you can see your score. If you have 12 points or less you belong to the green group. Between 13 - 15 points you belong to the blue group. If you score 16 points or more, you belong to the red group. Based on these colors, you will continue to work on the grammar exercises. If you think you fully understand the grammar exercises of you group, you are allowed to switch color. Do not forget to write this on your workplan!
