ANY OF THESE THINGS:
* Write stories (it would make our vocabulary even better than it is right now, since we might have to look-up words we aren't familiar with).
* Continue to use the aid "Feedback", which was introduced by Linda last year. (By applying "Feedback", you learn from your mistakes - it's easy to go back and check on the eve of a test.)
* Play games (might be a good practice in being orally active, you can speak English during the whole game).
