Suggestions

Been digging around the site for a suggestions page but I haven't found one yet.  I apologize if this is not the correct place to post this.  I'm fairly new to ChinesePod and am loving it so far.  I have a suggestion on the tests though. I am often getting the dictation questions on the tests wrong because of punctuation marks.  For example, the answer will have an exclamation mark and I will have used a period.  I don't think punctuation can always be clear from an audio clip.  Is there anyway we can be marked just on the chinese characters and not the punctuation?

Thanks!
