Hey, don't be so hard on yourself! If you checked your answers on the tests you say you flew through, and didn't just answer randomly, and you did your best in the spatial awareness questions, then I'm sure you'll have been fine. I didn't finish all the questions in S1 and I've just been offered a place on a course...
Something you might like to think about though....if you get through the recruitment process and onto a course, you may want to change your login name!
