Translation of characterize in German

Can we do it one day earlier? 30.April? I probably can't on the 04.05, but I will know just next week. Maybe we can do a phone lesson first and than the writing exercises. I do not feel ready yet.
Last week for example, I could have told you in advance that there is no chance for the other trials (if I knew): The traffic on the major website was too big. We should test it again sometime.
Not worth mentioning. The next day we spent the entire day in the mall buying unuseful things, cheap Jeans of poor quality and again gifts for our friends. I remember buying swimming pants in the sports store.
