Do Cambridge Prefer 4 A Levels? What Applicants Need to Know

Stop me if you've heard this before: "If you want a place at Cambridge, you basically need to take 4 A levels." Loads of sixth-formers get told this, and honestly, it's everywhere online. No surprise—everyone wants to get an edge. But is it actually true, or just another one of those school myths that refuse to die?

Here’s some straight talk: Cambridge does not require 4 A levels. Most offers are made based on just 3 A levels. Official statements from the university say this clearly, and they repeat it often. So why does everyone keep stressing about a fourth?

Yes, it can be tempting to sign up for an extra subject thinking it’ll boost your chances. But it's smart to know what Cambridge appreciates more: top grades in 3 solid, well-chosen subjects that actually fit your chosen course. No one at Cambridge is handing out offers just because you’ve stretched yourself thin across more subjects. Quality beats quantity, every time.

Why People Think Cambridge Wants 4 A Levels

You’ve probably heard the stories—your mate’s friend is convinced their cousin only got into Cambridge because they took 4 A levels. Some teachers even mention it as a way to shine, especially if you’re applying for competitive courses. And let’s be honest, scrolling through student forums like The Student Room just adds more fuel to the fire.

Part of this pressure comes from seeing some applicants take 4 subjects and get offers, then assuming the extra subject made the difference. Schools with ultra-high ambitions often push top students to do more—especially if they’re applying for tough subjects like Maths, Medicine, or Engineering. The thinking is simple: more A levels must look better, right?

There’s also the stats. A quick look at Cambridge’s own admission figures shows that quite a few successful applicants do have 4 A levels. Here’s a snapshot from one recent admissions report:

So yes, plenty get in with 3. But when you see that chunk with 4, it’s easy to believe that’s what Cambridge really wants.

Peer pressure is another big player. If everyone in your high-achieving circle is signing up for a fourth subject, it can feel risky to stick to three—even when you know, deep down, that piling on another class might actually pull your grades down or burn you out.

The catch? People often forget that correlation isn’t causation. These stats reflect high-achievers who might have chosen 4 A levels because they’re already really strong students—not because Cambridge demanded it. The university cares far more about top results in 3 solid, university admissions-friendly subjects than sheer numbers.

What Cambridge Officially Says

This is where things get real: Cambridge doesn't require 4 A levels. On their actual admissions site, Cambridge spells it out—they make offers based on 3 A levels, and that's the standard route for nearly everyone. You won’t spot anything about needing 4. In fact, they even say they prefer applicants to do really well in 3, rather than spreading themselves too thin over more subjects.

If you want to double-check, hop over to their undergraduate admissions FAQ. They literally say: "Our typical offers are based on achievement in three A level subjects." Only if you’ve somehow managed 4 without sacrificing your grades or sanity do they mention it could be noted. But it’s not a requirement or an expected thing, no matter what rumors float around school.

• Cambridge recommends you focus on subjects relevant to your chosen course rather than stacking up extra A levels just for show.
• If your school or college normally offers 4 A levels, Cambridge will see that on your application—context matters.
• The admissions team checks your grades and the difficulty of your subject choices, but not the total number just for the sake of numbers.

Here’s a quick reference:

The bottom line? Cambridge cares about the quality of your A-level results and if you’re ready for their course—not whether you've squeezed in an extra subject just for application points.

When 4 A Levels Might Help or Hurt

The big question: Can doing 4 A levels give you a real leg-up with Cambridge, or could it backfire? It honestly depends on your situation, the subjects, and how you cope with the workload. Let's break it down to save you the headache.

If you’ve got a natural knack for academic work and you’re smashing your subjects with high grades, then choosing 4 can make sense—if and only if all four really link to your intended course. For example, someone applying for Natural Sciences with Maths, Further Maths, Physics, and Chemistry is showing pure commitment. Some applicants taking Further Maths alongside Maths for competitive STEM courses are actually at an advantage, since Cambridge sometimes expects Further Maths for subjects like Computer Science or Engineering.

Here’s a table showing how 4 A levels fit in for different Cambridge courses:

But here’s the catch: If your grades in 4 subjects are lower than what you’d get in 3, that’s a problem. Cambridge isn’t looking for someone who bites off more than they can chew. They care about those A* and A grades in the right subjects more than a busy timetable.

Also, if you’re juggling extracurriculars, entrance exams, and interviews, ramping up to 4 A levels could mean serious burnout. Loads of past applicants say they wished they’d focused on fewer subjects and used the extra time to prep for the interview or research projects.

• Ask yourself if your school is used to students taking 4 A levels—some don’t even offer it.
• Consider how difficult the subjects are. Some, like Further Maths, add a heavy load.
• If you’re unsure, check suggestions for your target course on the Cambridge website. Their subject guides are brutally honest.

So, university admissions at Cambridge really comes down to: ace 3 relevant A levels, and only reach for a 4th if you’re sure it won’t pull you down. If you’re doing it just to impress, it’s not worth the stress or risk.

Subject Choices That Matter Most

Picking which A levels to take is not just about volume—it's about having the right ones that Cambridge cares about. This bit often gets ignored when people obsess over the number of subjects. Cambridge is super clear about loving what they call 'facilitating subjects.' These are traditional ones like Maths, Further Maths, Biology, Chemistry, Physics, English Literature, History, Geography, and Languages. For most courses, they want applicants to have at least two of these. Go for three and you’re looking solid.

Tons of courses have subject requirements you just can’t ignore. For example, if you want to do Medicine, you have to take Chemistry. If you pick Natural Sciences, either Maths or Science subjects are a must. Even for Economics, Maths is often a dealbreaker. And if you’re thinking of Engineering, you’ll straight-up need Maths and usually Physics too. Checking your course’s must-have subjects should be your first step, not an afterthought.

Some subjects look less impressive if you’re applying for rigorous courses. 'General Studies' and 'Critical Thinking' at A level? Cambridge usually ignores them for meeting their offer. Same goes for repeated or overlapping subjects (like both ICT and Computing)—they want depth, not just box-ticking.

It’s also worth knowing what other Cambridge applicants are actually choosing. For example, a 2023 admissions stat showed that Cambridge Engineering applicants most commonly took Maths, Further Maths, and Physics—and around 80% of successful applicants had those three.

So, don’t waste energy adding extras for the sake of it. Nail the three A levels Cambridge wants for your chosen course, and pick strong, relevant subjects. That’s what really matters if you want your application to stand out.

Application Tips Straight from the Source

If you want advice that actually matches what Cambridge looks for, skip the forums and rumors—go straight to the university itself. Cambridge admissions offices keep their expectations clear and don’t play games with applicants. Here’s what really matters, straight from them:

• Three strong A levels win over four average ones. Cambridge’s official advice says they don’t even expect four. They make the vast majority of offers based on three A levels, not four or five. Trying to juggle more and letting your grades slip? Not worth it.
• Pick subjects that match the course. If you’re applying for something like Medicine, Engineering, or Maths, hitting the required A levels (e.g., Chemistry for Medicine or Maths + Further Maths for Maths) is crucial. Going off-list for the sake of a fourth doesn’t add value.
• Check the ‘Essential’ and ‘Desirable’ subject lists. Cambridge’s website lays these out for every course. Stay focused—another random A level won’t make up for missing a required one.
• Show depth, not just breadth. Cambridge loves when you show real enthusiasm and understanding in your best subjects. That means stretching yourself with extra reading, super-curriculars, or projects—not just stacking up extra qualifications.
• Predicted grades count for a lot. If you’re predicted high grades in your chosen three, you already fit what Cambridge wants. Four predicted grades that dip below A* or A? That could drag you down instead.

If you’re looking for a boost, aim for the things Cambridge actually cares about: depth in relevant subjects, strong predictions, and genuine interest. They don’t reward you for burning out or spreading yourself thin. And if you really love a subject, go ahead and take a fourth—but make sure it lifts you up, not drags you down.
