["I had a test at work the other day.  I wasn't really fretting it though.", 'Did you study?', 'Yeah I felt really prepared.  I knew going into it that I had done everything I needed to , and felt good about my abilities.']

I went into a test at work the other day.  I knew that I had been training for it for a while, and felt good about my abilites going into it.
