Hi Jonas. These questions are the same. The second question ends with the preposition "at", which is considered bad grammar. In English, we are taught never to end a sentence with a preposition, however, most people do it anyway, because it feels more natural. A common example of ignoring this rule is the question "Where are you from?" This question ends with a preposition, but rearranging the words makes it sound strange. And in this example, the word "from" is important. It can't be left off as in the questions you asked about. I hope this helps! :)
