Then once you have a date that is convenient, go to the Stapleford on-line booking system to see what hourly slots I have available.
The On-Line Booking System can be found by Clicking Here and then login in with the account name "SEStudents" and the private password Steve has given you. Choose the date you want and check for a free slot that is convenient to you.
Then to actually book the slot call the Stapleford Reception on 01708 688380 between 08.00 and 18.00 to reserve the Slot.
