Hi
Can you please let me know how the SQA work out your mark for 2018 paper. Do they add both marks/ by 110 and then multiply by 100
Please reply
Thanks for taking the time to make tgese videos.

Hi Peter
The SQA tend to just look at your total marks as opposed to your overall percentage. All marks achieved will be added together across both papers. Once all marks are totalled up for all pupils, grade boundaries are decided on by the markers. These slide up and down each year depending on how pupils have found the exam. Roughly speaking it will always be the same percentage of candidates who will get an A, B, C etc but the marks needed to achieve the grades changes slightly from year to year. Last year you needed 73% for an A, 62% for a B and 51% for a C.
Last year’s course report is available at https://www.sqa.org.uk/files_ccc/MathematicsN5CourseReport2017.pdf

Hi
First off, thanks for the reply. The College mentioned that what they will do, is take both marks from both papers and divide by the total mark. ex. 30 plus, 34, divided by 110 and then mulitplied by 100 and this would give the grade. Is this the case? I have looked everywhere and cannot find this out. No-one seems to know, Many Thanks

What i’m looking at, is they have looked over the paper, then they add both marks, then what do they do to find the percentage,?
Last comment from me,

They just add the two marks, divide by the total 110 and multiply by 100. Hope all went well in the exam!
