I watched your OCR videos and without them, I don't think I could have done even 3/4 of the exam. They were great

Thank you so much, your videos are fantastic. I have my exam on the eighth of June, and you have retaught me the majority of the things I need to know. Such succinct and clear explanations for everything

I think that you have saved me!

Hi! I picked my options for GCSE about a month ago, and even though CS gcse's aren't even close yet, I am still finding this very helpful.
Thanks! :)

[TheWatkinator]

In the pseudocode question you used '=' as both an equality operator and an assignment operator instead of using an arrow/double equals etc. for differentiation. Your vids are great though, hopefully I should get a good grade in my exam because of them!

[sammytarafdar]

Your videos are very helpful! The only thing is I can't find a video covering handling external data(3.1.7 of the specimen). If you could possibly explain it in a video or otherwise if you haven't already. Thank you!

[Tez]

Thank you very much for your videos! Never understood trace tables with pseudocode before this! So thank you! :D

I had the OCR exam this Wednesday and there was a question worth 4 marks which was on client server networks and basically why a supermarket with cashier computers should use a client server network instead of a peer to peer network. I firstly wrote that: By using a client server network, if all the computers fail then the customers data won't be lost as they will be saved in the client computer. Second point: With a client-server network, the cashier computers can seamlessly be replaced as the data is in the server and therefore it doesn't make the customers data vulnerable. Out of 4 marks where each point is worth 2 marks how many marks do you think I got?
