How Many A-levels Do You Take? 2, 3 or 4 Compared

Most students take three A-levels, and universities such as Oxford, Cambridge and Bristol base their standard offers on three. You can take two or four instead. Two can work for some points-based courses, while a fourth rarely changes what you're asked for, so three strong grades is the safest plan for most people.

If you're picking sixth-form subjects right now, don't stress. There's no wrong number, only a number that fits the courses you want. This page sticks to the "how many" question. For the basics of how A-levels work and how they're graded, start with A-levels explained, then come back here.

How many A-levels do most students take?

Three. The Department for Education's Skills for Careers service says most people choose 3 subjects, but you can take more or fewer, and you can study a BTEC or another qualification at the same time. There are more than 40 A-level subjects to choose from, so when people ask "how many subjects are in A-levels", they usually mean how many you study, not how many exist.

At Cambridge, four is common too: it says most of its applicants study three or four A-level subjects.

Your school or college also shapes the answer, because it decides which subjects it can fit into the timetable and sets its own entry rules. Ask what's possible before you plan around a fourth subject.

If you're weighing up A-levels against vocational courses, our guide to how BTECs compare with A-levels shows how they fit together.

How many UCAS points are 2, 3 or 4 A-levels worth?

Every A-level you pass adds its own points, so your total grows with each subject. Here's what one A-level is worth at each grade:

And here's the same grade, B, across two, three and four A-levels:

Look at the "same total" line under the four-B box. On the UCAS Tariff, an extra subject can make a set of middling grades add up to the same number as a top-grade set of three. That helps with points-based offers, but it doesn't help with grade offers. Oxford puts it plainly: three A*/A grades would meet most of its conditional offers, "but two A*s and two Bs would not."

To check your own grades, use the UCAS points calculator or the A-level UCAS points calculator. If you're curious about the ceiling, see the maximum UCAS points you can get. Not sure what you're aiming for yet? Our guide to how many UCAS points you need helps you set a target.

Do universities prefer 4 A-levels?

Mostly, no. Cambridge and Bristol say plainly that a fourth A-level gives you no advantage, and Oxford makes its offers on three however many you take. Here's what each says on its admissions pages, checked in October 2026:

Two details are worth knowing. First, Oxford treats Maths and Further Maths as separate A-levels, so Further Maths counts as a genuine fourth subject. Second, Oxford's offer may name the three subjects it wants the grades in, so a fourth A-level can't always stand in for a weaker one.

If Oxford or Cambridge is on your list, our pages on Cambridge entry requirements and UCAS points and Oxford entry requirements cover their offers in more detail.

Is it better to do 4 A-levels or 3?

For most students, three is better. Three strong grades meet the offers above, and four slightly weaker grades often don't. The biggest risk with a fourth is the one Oxford flags: spread yourself across too many subjects and you may "risk dropping a grade or two". Oxford also points out that extra A-levels can eat into the time you'd spend reading around your chosen subject.

A fourth A-level makes more sense when:

• You're aiming at maths, physics, engineering or another STEM degree, and your fourth subject is Further Maths. Cambridge says strong STEM applicants usually take it.
• You genuinely enjoy all four, and your predicted grades are holding up in every one.
• Your school lets you start four in Year 12 and drop one later, which can be a low-risk way to test the workload.

It makes less sense when the fourth is a "just in case" subject, or when it's a heavy subject on top of three demanding ones. Before you commit, compare the workload in our guide to the hardest A-levels.

Is 2 A-levels enough for university?

Sometimes. It depends on how the course words its offer.

Grade offers list three grades, such as AAB. They're the norm at Oxford, Cambridge and Bristol: Oxford says its offers are normally made on three A-levels, and Bristol's standard requirement is three A-levels "or equivalent qualifications". With only two A-levels, you can't meet a three-grade offer unless the course accepts another qualification in place of the third.

Tariff offers ask for a points total, and some set a minimum number of A-levels rather than three. For example, for 2027 entry Bournemouth University's Multimedia Journalism degree asks for 112–128 UCAS tariff points "from a minimum of two A-levels". It also accepts the EPQ towards that total, as long as it sits alongside two A-level-sized qualifications.

Here's what it takes to reach the bottom of that range from two A-levels on their own:

That's two of the highest grade available. So unless you're sure of two top grades, you'd need something else to make up the points, such as an EPQ, an AS-level or a vocational qualification. You can add them all together in the mixed qualifications calculator, and our guide to mixing qualifications for university explains how universities treat combinations.

Watch the EPQ rule, though. Bristol says it does "not accept this qualification in place of an A-level", so at Bristol, at least, an EPQ tops up your application rather than replacing a subject.

If two A-levels won't get you onto the course you want, a foundation year is another way in. For 2027 entry, Bournemouth's Multimedia Journalism with Foundation Year asks for 48–72 tariff points, including one A-level or equivalent. Our guides to foundation years and going to university without A-levels cover the other options.

Can you do 3 A-levels in one year?

It's possible, but it's hard going. Fitting three A-levels into one year means covering a lot of content fast, which is a big ask if you're also working or caring for someone.

Universities view timing in different ways:

• Cambridge bases its offers on three A-levels taken together in Year 13.
• Oxford says its usual expectation is that candidates complete their A-levels within a two-year period, including all the units that make up the final grade.
• Bristol says A-levels "can be completed in multiple sittings", and it considers resits on the same basis as first attempts.

So spreading your A-levels out is fine at some universities, while others prefer them sat together. If you're planning a one-year route, check how your target universities view it before you start. For adults, our guide to taking A-levels as an adult explains how it works, and if you're redoing a grade, see retaking A-levels for UCAS points.

Can an EPQ or AS-level replace a fourth A-level?

As an extra on top of three, yes, though both earn fewer UCAS points than a full A-level. If you want something extra without a fourth full subject:

• The EPQ (Extended Project Qualification) is encouraged by Cambridge because it builds independent study and research skills, though Cambridge says completing it "won't normally be a requirement of offers". Oxford says it won't be a condition of any offer. It still earns UCAS points, which matters for tariff offers. See our guide to the EPQ and the EPQ points table.
• An AS-level is a standalone qualification. Oxford says completed, cashed-in AS-levels can be listed as separate qualifications, but its offers are based on final A-level grades. Bristol has no AS requirement and gives no preference to standalone AS-levels. Check what each grade is worth in the AS-level points table.

The pattern is simple. Oxford bases its offers on final A-level grades and Bristol won't take an EPQ in place of an A-level, so at universities like these an EPQ or AS-level adds to your application rather than replacing a subject. At points-based universities such as Bournemouth, an EPQ can count towards your total.

How many A-levels should you take?

Work it out in this order:

1. Look up two or three real courses you might apply for, and note whether each offer is in grades or points.
2. Count the grades in each offer. If they all list three, plan for three strong A-levels.
3. Check the subject requirements. A required subject matters far more than an extra one.
4. Add a fourth only for a clear reason, such as Further Maths for a STEM degree, and only if your grades in the other three won't suffer.
5. Consider an EPQ instead if you'd like extra points or research experience without a full fourth subject.

Once you have predicted grades, put them into the calculator to see where you stand against your courses.
