Thank you for helping me pass my AS in Computer Science. I changed school and computer science was a huge jump for me. At the start of the year I struggled greatly and so did a lot of people in my class, but I found your videos on YouTube and for the exam I watched every single video you had for the A level specification, writing notes on every video. Because of those videos I was the only one in my class who did ICT for GCSE who passed Computer Science.
