Hello ma'am. I am commenting from romania and am currently in year 12 getting ready for my unit 3 paper tomorrow. Thank you for your videos as they proved to be very helpful for units 1 and 2 and will also be for unit 3. I just wanted to ask where you are from and where you are based, because its uncommon to see this much support materials on International A level
