I've now uploaded the analysis of 2024 exams to https://www.paullong.net/gcse-computer-science-exam-analysis-2024/

This is FREE to download and use. Sorry it's taken so long. I wanted to give AOs a chance to feedback and I ended up adding in some extra analysis comparing papers 1 and 2.

Hope this isn't too late to be tagged on to any exam reports you all have to do for SLT.

GCSE Computer Science Exam Analysis 2024 - paullong.net This presentation shows a summary of the GCSE Computer Science exam statistics in 2023 and compares them with 2019 and 2023, looking at common misconceptions related to grade boundaries. It uses data and graphs from an interactive spreadsheet which is also available to download.

I'm delighted to let you all know that the Walking Talking Mocks for the Edexcel 2022 Paper 2 are now available. There are 2 sample videos at https://www.paullong.net/product/walking-talking-mocks/ that you can watch. These are essential for students in understanding how to answer in the exam, whether you do this in exam conditions, in class or set for flipped learning homework. As they are based on 2022 papers, they are only available to schools / teachers. This has been 20 days of work and a lot of effort into the detail so I hope you find them useful.

I hear lots of questions about the practical programming statement (PPS). What is it? When do I need to sign it? Do I need to send off a spreadsheet? Do I need to send off a sample? The PPS is a simple statement whereby a teacher or senior leader from the centre (school/college) needs to confirm that the centre has met the programming requirements within the GCSE Computer Science specification....

Command words are the words usually used at the start of a question in an exam. Examples include identify, describe and explain. They are supposed to inform students how to answer a question. However, did you know that for GCSE Computer Science, AQA use 28 different command words, OCR use 30 different command words and Edexcel use 15 different command words?...

One of the most common questions I get asked is about how to set grade boundaries for mocks or other internal exams. Many teachers will suggest using past paper grade boundaries, but I'd like to explain why this is not always good practice. If the paper that you are setting is a genuine unedited past paper and you want to benchmark your students' performance, then yes, do use the grade boundaries that were set for that paper....

Really pleased to announce that I have finally got a new website at www.paullong.net that is more reflective of the high-quality Ultimate GCSE resources I provide (I've put off updating from an outdated Microft Expression Web website for too many years while I've focused on developing resources for schools to use). Massive thanks to Sam from Craig'n'Dave who has been instrumental in setting up the structure, style and initial content, and helping me to get started.

You'll find some very generous discounts on Programming Project materials which are still very relevant for students studying for 2022 exams because programming is still a very big part of the assessment and so programming practice is essential.
