Do we need to learn how to code/write algorithms in Computer science ocr a level?

Hello i've been revising algorithms and I am wondering if we need to learn how to write these algorithms in pseudocode/high level language eg for merge sort or quicksort? They seem really complicated to program and I feel a bit worried about having to actually code these...

If you check Craig'n'Dave, there's a table saying how much you need to learn for what. I think you need to be able to code all of them apart form A* from memory, but it's worth checking.

Dang I see thanks, that's a shame rip

If you do find a good way to memorise how to code the Quick sort and the Merge sort, please do reply and let me know. I am in the same boat as you; the rest are easy enough to code, if you could also show how you remembered insertion sort!

i think making flashcards for each of them, and doing them every now and then would be the best idea. that's what I'm going to do! but yes if anyone has any other methods do let us know :smile: btw what exam board are you doing? mines OCR.

I think they're doing OCR :wink:

What she said is half true. You need to code linear search, binary search and bubble sort from memory. For the other three, as they are lengthy algorithms with recursion and a supplementary algorithm to help it complete, you just need to fill in the blanks. I am speaking from OCR as I do that, not sure about AQA. Hope this helps!
