Assuming you're doing a JAR PPL (not sure what they offer at OFT or if the same applies for a FAA PPL anyway), you'll need to pass Air Law before going solo. I know you've got time before August to knock the exams on the head so it shouldn't be a problem, but I hadn't picked up on this until about 10 hours into my my PPL here in the UK - it meant getting Air Law out of the way pronto.
