IB vs A-Levels - A Comprehensive Guide

As of May 2024, over 5,000 UK students are enrolled in the International Baccalaureate Diploma Programme. However, this figure is still significantly lower than the number of students taking A-Levels: as of 2024, nearly 800,000 sixth formers nationwide took their exams, up from 780,000 in 2021.

The International Baccalaureate Diploma Programme was created to provide a more holistic, rounded education., by continuing the multi-subject structure students experienced in secondary school. A-Levels, by contrast, are more specialised, and focus on a few subjects that the student intends to take to university level.

But what are the fundamental differences between the two? Why do some students take the International Baccalaureate (IB), and how does it affect their university prospects? This article will show you the difference between IB vs A-Levels – how they’re graded, how they’re structured, and how they’re perceived by universities – to help you establish which would be the best fit for you!

What are A-Levels?

Since 2015, UK students have been legally required to stay in education until the age of 18. A-Levels (or Advanced Levels) are the most popular school-leaving qualifications in the country, and are usually completed between the age of 16 and 18.

A-Levels focus on three or four subjects, which are studied in-depth. No subject is compulsory, but there are more than 50 to choose from! As of 2020, most A-Levels have no coursework, and are entirely exam-based.

What is the IB?

The IB is an alternative school-leaving qualification for students aged 16 to 18. It offers a wide, varied syllabus made up of 6 subject groups – usually, students take three as a more extensive Higher Level (HL) course, and three as a Standard Level (SL).

All students study two modern languages, an experimental science, a humanity or social science, and another subject e.g. arts. Alongside this, they complete a curriculum of extra classes and activities intended to develop critical thinking and study skills. This includes a two-year course called Theory of Knowledge (TOK), an Extended Essay, and a Creativity, Action, Service program (CAS):

TOK: A 1,200-1,600 words on a title (from a choice of ten), followed by a 10-minute class presentation.

Extended Essay: a research project culminating in a 4,000-word essay on a free-choice topic

CAS: 150 hours over an 18-month period in any form of creativity, a social service, a sport or other physical action.

By now, the basic differences between IB vs A-Levels should be clear! The A-Level course is made up of a few, discrete subjects studied in-depth and separately from extracurricular activities. The IB Diploma programme instead focusses on building core skills across a wide range of interconnected subjects, with incorporated extracurriculars.

Recent Trends in IB and A-Level Enrollment

In recent years, the number of students enrolling in the International Baccalaureate (IB) has seen a gradual increase, with over 5,000 students in the UK participating as of 2024. Meanwhile, A-Levels continue to dominate with nearly 800,000 students taking the exams in 2024. These trends highlight the sustained popularity of A-Levels, though the IB is gaining traction, particularly among students seeking a more holistic educational experience.

How Are They Graded?

The IB Diploma Programme continues to use a points-based system, with each subject graded on a scale of 1 to 7. However, the overall diploma score also factors in the student’s performance in core components like the Extended Essay and Theory of Knowledge (TOK), with the maximum possible score remaining at 45 points.

This final Diploma score is made up of the combined equivalent points value of each course’s letter grade. You need 24 points or above to be allowed to complete your diploma, and a perfect score is 45 points.

However, A-Levels are simply graded A-E, with A* as the top grade. When it comes to complexity, the winner of IB vs A-Levels is clear; IB results can look impressively confusing!

Evolving Assessment Methods in IB and A-Levels

The IB and A-Level grading systems have both evolved in recent years to better reflect the diverse skill sets students are expected to develop. While the IB's points-based system remains, there is now a greater emphasis on coursework and continuous assessment. A-Levels, traditionally exam-focused, have also seen changes with some subjects reintroducing coursework components to provide a more comprehensive evaluation of student performance.

Is the IB harder than A-Levels?

When answering this question, it’s hard not to overlook the subject demand of the IB. Although there is a case to be made that universities ask for top A-level grades, it's undeniable that achieving high grades in six subjects is more work than three or four, which is why so many students choose to hire a private IB tutor. Just from a sheer time perspective, the IBs are more demanding of their students on a day-to-day basis.

More subjects mean more time spent in class and less time for free periods. Alongside that, many of the IB subjects have a heavy coursework portion of their qualification. That means even more time outside the classroom. While trying to keep up with homework, studying, coursework, and exam prep, six subjects can be overwhelming. Another factor that pushes IB ahead of A-levels when it comes to difficulty is the additional portions.

Moreover, research supports the notion that the IB is a more challenging program. For example, "Recent studies from 2023 by the Higher Education Policy Institute (HEPI) confirm that IB students are more likely to exhibit higher levels of critical thinking and problem-solving skills compared to their A-Level counterparts.

When we look at the percentage of students achieving the top grade, we see that it's harder to get a 7 in the IB program than it is to get an A* in A-Levels. According to data from the Joint Council for Qualifications, 19.1% of A-Level grades were awarded an A* in 2021, which is a slight increase from the previous year. In comparison, only 12.6% of IB grades were awarded a 7 in 2021, also an increase from the previous year. These numbers indicate that achieving the highest grade in the IB program is more challenging than getting an A* in A-Levels. However, as over a quarter of secondary school students in the UK hire an A-Level tutor, many students do find this qualification tough.

The IB was designed with a full education in mind, the end goal is to produce a well-rounded pupil. Due to this, the Extended Essay, Theory of Knowledge, and Creativity, Action, and Service segments of the IB require additional work. Just focusing in on the CAS, this element requires you to finish an activity that fits into one of the three headings, every single week. You would have to play an hour of sport, take a skill or development class such as photography, and volunteer some of your time each week. That’s all alongside coping with the additional subjects. While A-levels have their own set of difficulties, the extra hours needed to complete the IB really take their toll.

Another key point to note is that the IB program offers courses in over 50 languages, allowing students to study both native and new languages. For instance, many IB tutors in Spain specialise in Spanish, while Italy IB tutors focus on Italian, helping students excel in their studies. In comparison, A-Levels offer around 15 language options, providing a more specialized focus. Despite fewer options, A-Level language courses offer deep and comprehensive learning in the chosen subjects.

IB vs A-Levels: Which Do Universities Prefer?

In the University Officers Report 2017 (a survey of the people who decide which students are admitted to uni), officers assessed that the IB is better at encouraging a “global outlook” and “independent inquiry” in students, while A Levels give students more “detailed and in-depth expertise”.

This doesn’t exactly tell you which one universities prefer. That’s because the true answer is entirely subjective; whether you should take the IB vs A-Levels depends entirely on where you want to go to uni, and what you want to study.

Statistics show that students taking an IB Diploma have a 38% higher chance of graduating from university with a Bachelors’ degree. However, this could be because the IB is favoured by private schools: in May 2020, the top performing schools in the IB were King's College School - Wimbledon (average score of 41.7), Godolphin & Latymer School (41.3); Sevenoaks School (40.1); and Whitgift School (40).

In short, there’s no way of saying for sure whether universities prefer the IB vs A-Levels. As a rule, if you’re studying in the UK, A-Levels are the most widely accepted option, and the benchmark against which the course entry requirements will be set. Yet if you’re planning on studying abroad – such as in the US – the IB is the most widely understood qualification.

Shifting University Admission Trends

As of 2024, universities are increasingly adopting a more holistic approach to admissions, considering not just academic performance but also extracurricular activities, leadership experiences, and personal statements. While the IB's emphasis on a well-rounded education aligns well with these trends, A-Levels continue to be highly regarded for their subject-specific depth, making both qualifications highly respected depending on the student's academic and career aspirations.

IB to A-Level Conversion

The easiest way to compare and convert IB performance to A-Level performance is UCAS points. The easiest way to compare and convert IB performance to A-Level performance is UCAS points. When you apply to university, UCAS converts both A-Level and IB grades into points – that way, they are both equally weighted in meeting course requirements.When you apply to university, UCAS converts both A-Level and IB grades into points – that way, they are both equally weighted in meeting course requirements.

As we’ve discussed earlier, the minimum score needed to pass the IB diploma is 24 points. This equates to 260 UCAS points. The standard admission requirement for UK universities is 260 points; a number that can also be reached by attaining 3 C-grade A-Levels. This suggests that a 24-point IB score is equivalent to 3 A-Level Cs.

On the other hand, 3 A*s at A-Level equates to 420 points, which is the same UCAS points value you’d receive for a 43 IB score. The most selective universities – such as Oxford – ask for 360 points on average. This is 3 As, or 38 IB points.

However, most universities’ course requirement pages will specifically describe the number of IB points you need, alongside the A-Level grades. This is because even admissions officers can’t pin down the conversation rates: 72 percent consider an IB 43 to be equivalent to 3 A*’s at A level, when only 3% of IB students achieve this grade, compared to 12% of A-Level students achieving 3 A*s.

How to prepare for the IB and the A-Levels?

Preparing for both the International Baccalaureate (IB) and A-Levels involves strategic planning, diligent study habits, and access to supportive resources.

Here’s a guide to help you get ready for both educational pathways:

Find the Right Tutors

• For IB: Seek out IB tutors, such as qualified IB Maths tutors or IB English tutors, who understand the broader requirements and integrated approach of the IB.
• For A-Levels: A-Level tutors often specialise in one subject, such as A-Level Maths tutors, or A-Level Biology tutors, providing detailed knowledge and preparation techniques specific to that subject.

Use Quality Study Materials

• IB Resources: Utilise study notes and practice questions from reputable IB resources created by experienced IB educators such as the following:
  • IB DP Past Papers
  • IB DP Study Notes
  • IB DP Practice Questions
• A-Level Resources: Obtain comprehensive revision guides and past exam papers which are crucial for understanding the exam format and expectations such as:
  • CIE A-Level Past Papers
  • AQA A-Level Past Papers
  • Edexcel A-Level Past Papers

Develop a Study Schedule

• Consistent Study: For both paths, regular and consistent study is crucial. Dedicate specific times for each subject and rotate your focus to cover all areas adequately.
• Balanced Approach: Since IB requires engagement with core components, allocate time for TOK, CAS, and the Extended Essay without neglecting subject-specific studies.

Practice Exams and Feedback

• Mock Exams: Regularly taking practice exams for both IB and A-Levels can help you identify areas of strength and weakness.
• Seek Feedback: Use feedback from tutors and teachers to refine your understanding and improve your answers.

Focus on Skill Development

• Critical Thinking and Analysis: Both educational paths value the ability to think critically and analytically. Engage with materials and questions that challenge your reasoning skills.
• Time Management: Learn to manage your time effectively during study sessions and exams, as this is critical for performing well under the timed conditions of both IB and A-Level exams.

By understanding the specific demands of both the IB and A-Levels, utilising specialised tutoring, and practicing diligently with the right resources, you can effectively prepare to excel in both academic pathways.
