What are the Edexcel (Pearson) AS Grade Boundaries in 2026 and Why Do They Matter?

How to interpret 2026 grade boundaries for Edexcel (Pearson) AS exams

Exam boards like Edexcel (Pearson) set grade boundaries based on how students perform each year. These boundaries only get decided after all the marking is finished.

Edexcel (Pearson) uses a mix of statistical analysis and examiner expertise to keep things fair and consistent with previous years. Because every exam paper is slightly different, one year’s paper might be a bit harder than another’s. If lots of students struggle with a particularly tough paper, the grade boundary drops slightly. That way, nobody gets unfairly penalised.

Checking previous years’ Edexcel (Pearson) AS grade boundaries gives you a pretty good idea of what you’ll need to score in 2026 for your target grade. Match this up with your scores on Edexcel (Pearson) AS past papers and you’ll see where you currently stand. You’ll spot exactly how many extra marks you need for that higher grade. Then you can focus your revision to bridge that gap.

Important: During the COVID-19 pandemic, Edexcel (Pearson) lowered the AS grade boundaries for 2020-2022 to help students who’d missed school during lockdowns. Those years aren’t typical, so don’t rely on them too heavily when predicting your grade.

How do weighted grade boundaries work?

Some courses have more than one exam paper (or component) and not all of them count equally. To make sure each paper gets the importance it deserves, exam boards use something called weighting factors.

Working out your weighted grade

Here’s a simple step-by-step guide to how it happens:

1. You get a raw mark for each paper (this is just the mark the examiner gives you).
2. Each paper gets multiplied by a weighting factor, which turns it into a weighted mark.
3. All your weighted marks are added up to give you your total course mark.
4. This total gets compared with the grade-threshold table for your exam session to decide your final grade.

A quick example

Let’s say you’re sitting two papers:

• Paper 1:
  • You score 64 out of 80
  • The weighting is 1.25
  • So your weighted mark is 64 × 1.25 = 80
• Paper 2:
  • You score 70 out of 100
  • The weighting is 1
  • So your weighted mark is 70 × 1 = 70
• Your total:
  • 150 weighted marks

If the grade B boundary is 150, congratulations – that’s your grade!

Remember, grade boundaries change each exam series. This means the same total mark might lead to a different grade in another year. So, don’t compare your marks with your friend who sat the exam last summer — the boundaries could be completely different!

What is the best way to prepare for your AS Edexcel (Pearson) exam?

If there’s one golden rule to follow, it’s to start early. Make a list of every topic across all your AS courses and highlight the ones that make you feel less confident. Then build a revision timetable with short, focused sessions - giving extra time to your more tricky topics.

It’s important to revise everything covered in your syllabus. However, focusing on your weaker areas first means you’ll see the biggest jump in marks where it counts.

At Save My Exams, our teacher-written resources pinpoint exactly what to revise, help you identify your weak points, and show you how to improve, so you can walk into your exams confident and prepared. Try this:

• Use revision notes to nail the Edexcel (Pearson) AS content.
• Then move onto flashcards to test yourself and make information stick.
• Once you’ve got the basics down, practise with some exam questions. They’ll show you exactly what you know (and what you don’t).

Tip: Practice with 2026 Edexcel (Pearson) AS past papers under real exam conditions. Set a timer, sit somewhere quiet, and work through the whole paper. This builds your time management skills and, just as importantly, your exam stamina.
