What dates do I put?

<p>I'm wondering what dates I should put on certain areas of the applications. For example, I'm taking a post-secondary class while in high school right now. I'm supposed to write the dates attended... do I just put the starting date to the present, or should I write the ending date as when I will be done with the class? The same goes for the credit earned, since I will have 8 credits when it's done, but only have 4 now...</p>
