    You sir are amazing, I watched the paper 1's and was able to widen my knowledge significantly with your brilliant explanations, please keep doing more paper 2 content as that is very difficult, Thanks.

    • @ComputerSyth

      Very kind of you to say so, thank you, but the reason I think I can keep my explanations simple is because it is not the subject which I studied the furthest at university.
      I had to learn computer science in my second year as a teacher due to another teacher leaving.
      Because I am not a million miles ahead of my students, I can keep my explanations simple.
      At school, I had a Doctor of a subject teach my class, and we didn’t learn anything, because he wasn’t able to come down to our level.

      I would love to help, but I teach the OCR specifications at GCSE and A Level and have previously taught A Level AQA so I would have to do some research first and would need to get hold of the past papers.

    sir for 48:27 on line 5 dont you have to typecast num1 and num2 from integers to strings as you cannot concatenate int and str?

    • @ComputerSyth
      @ComputerSyth  7 месяцев назад +1

      If programming, yes, I agree.
      But for pseudocode, the rules are less rigid

    hi there aagin just a bit concerned at 11:30 as i would like to know if i am in the exam and if it was to be a simnilar scenario would i not get the mark if i did not put start as 3 for line number 3 and vice versa

    • @ComputerSyth
      @ComputerSyth  7 месяцев назад

      Can you clarify what you mean?
      Are you asking if you left the middle column blank, would you get the mark still?
      (assuming you still output the value of start on line 3)

    • @ComputerSyth
      @ComputerSyth  7 месяцев назад

      It’s essentially a test of whether you can follow (trace) an algorithm, and record when variable values change, and when (as directed) you output values.
      That’s what this type of question is designed/intended to test you on.

      It’s a possibility… but I am a teacher full time, and have a last minute revision/AMA session at work the morning of the exam, so need to make the priority the number one priority but I will see.

    • @ComputerSyth
      @ComputerSyth  7 месяцев назад

      Ultimately, preparation is on us as individuals, so my advice would be to use whichever resource you prefer (CSNewbs website/IsaacComputerScience website/Craig n Dave channel/BBC Bitesize) and try to do some ‘active recall’ (revise for 30 minutes, do some relevant PPQS for 15-20 mins, then take a short break to refresh/drink/eat/walk around)

    • @ComputerSyth
      @ComputerSyth  7 месяцев назад

      As a teacher, I may well have access to things which aren’t immediately available to all.
      I have looked on OCR’s public site and cannot see it, so it would be something your teacher can give you to practice with.

    • @ComputerSyth
      @ComputerSyth  7 месяцев назад

      My suggestion would be to email your teacher to ask whether they can print a copy or share it with you.
