['I have a big test next week. I should be able score high. I know the material really well.', 'Thats great news.  Did you have to study or is this an area you are already familiar with?', 'I have been studying. I always do well in this subject so it should be a breeze.']
Awesome, good luck on your test! I hope it all goes well!
I have a big test next week. I plan on getting a really high grade. I know the material really well.
