Choosing your A-levels can be exciting until you discover that the subject you really want to study is not available at your school or college. Perhaps there are not enough students to run the course, the timetable does not work, or your sixth form simply does not teach that particular subject.
That can be frustrating, especially if the A-level relates directly to something you hope to study at university. However, your school’s timetable does not necessarily have to determine which qualifications you can take.
One option is to study the missing A-level separately, including through an online provider, while continuing with your other subjects at school or college. Before doing that, there are some practical questions to answer about workload, examinations and whether you genuinely need the subject for your future plans.
Why Might a School Not Offer a Particular A-Level?
Sixth forms cannot realistically offer every A-level subject available.
Some subjects attract relatively small numbers of students, making it difficult for a school to justify running a class. Others require specialist teachers or facilities that may not be available.
Timetabling can create another problem.
Your school might offer both subjects you want, but place them in the same option block. In practical terms, that can leave you facing the same problem as if one of the subjects were unavailable altogether.
There can also be entry requirements for particular courses. A sixth form might offer an A-level but require a certain GCSE grade before allowing a student to enrol.
Whatever the reason, it is worth establishing whether the problem is absolute. Ask whether another local institution offers the subject, whether there are partnership arrangements between schools or whether an alternative timetable is possible.
If those options do not solve the problem, independent study becomes worth considering.
Can You Study an A-Level Your School Doesn’t Offer?
Yes, it can be possible to study an additional A-level independently.
Online learning removes the need for your chosen subject to fit within the physical timetable of your sixth form. You can work through a structured course separately and organise your study around your existing commitments.
The range of distance learning A-level courses includes subjects that students may not always find available locally.
This does require more independence.
Your school day will already contain lessons, homework and revision for your other subjects. An independently studied A-level has to fit around that workload rather than replacing it automatically.
Before enrolling, calculate when you will realistically study each week.
The fact that an online course can be accessed whenever you like is useful, but flexibility only works when you actually reserve enough time to use it.
Can You Study Three A-Levels at School and Another One Online?
Potentially, but think carefully before doing so.
Studying three A-levels at school and adding a fourth online means you are taking on a substantial academic workload. The fourth subject will still contain a complete A-level specification and ultimately require the same standard of assessment.
There are situations where this arrangement makes sense.
Perhaps you genuinely enjoy the additional subject, or it gives you an academic combination that your school cannot provide. Further Mathematics is one example of a subject some students may want but cannot access locally.
The important question is whether adding another A-level helps you more than concentrating your effort on the three you already have.
Our guide to whether it is worth taking four A-levels looks at that decision in more detail.
Do not take four simply because you can. Take the additional subject when there is a clear reason for doing so and you have enough time to study it properly.
What If You Need the Missing A-Level for University?
This is where checking university requirements early becomes particularly important.
Some degree courses require applicants to have studied particular A-level subjects. If your intended degree has a specific requirement and your school does not offer that subject, ignoring the problem could restrict your options later.
Start with the universities themselves.
Look at the current entry requirements for several courses you might realistically apply to. Do not rely on assumptions about which subjects sound useful.
For example, certain science and medical routes can have specific subject expectations, while many other degrees are much more flexible.
Our article on whether universities care which A-levels you take explains why the answer varies considerably between degree subjects.
If a particular A-level really is required, studying it independently may provide a route around the limitation of your school’s curriculum.
Should You Choose a Different Subject Instead?
Sometimes that is the simplest solution.
If the unavailable subject is not required for university and you have another option that genuinely interests you, choosing from your school’s existing timetable can make life considerably easier.
You will have classroom teaching, school-based support and a timetable already designed around your other subjects.
Do not assume, however, that two subjects are interchangeable simply because they appear related.
If you are changing your choices because your preferred subject is unavailable, investigate how the alternative affects your longer-term options first.
The decision should also reflect what you actually enjoy studying. Our guide to which A-levels go well together can help you think about combinations rather than viewing each subject in isolation.
A sensible alternative can be a good solution. A random replacement chosen only because it fits the timetable is less convincing.
Will Your School Help If You Study an A-Level Independently?
This depends on the school.
Some sixth forms may be supportive of students studying an additional subject independently, while others may have limited capacity to provide help for a qualification they do not teach.
Have the conversation before assuming either way.
Explain what you want to study, why you want to study it and how you intend to manage the workload. If the subject is important for a university route, make that clear.
You should also establish whether the school is willing or able to help with practical matters such as examination entry.
Do not assume that attending a school means it must automatically enter you for an independently studied subject. Examination arrangements need to be confirmed separately.
A clear conversation at the beginning is much easier than discovering conflicting expectations close to the examinations.
Where Would You Sit the A-Level Exams?
Online study changes where you learn, but it does not remove formal assessment requirements.
If your school agrees to enter you for the qualification, you may be able to complete the relevant examinations there. If it cannot or will not do so, you may need to arrange entry through another approved examination centre as a private candidate.
Our exams and assessments guidance explains the main considerations for students preparing outside a conventional classroom.
Start investigating this well before the examination period.
Different centres can offer different subjects and services, and some qualifications have additional assessment requirements that make arrangements more complicated.
This is particularly important for subjects involving practical work, coursework or other non-exam assessment.
Finding a course is only one half of the plan. You also need a realistic route to completing its assessments.
Can You Study an A-Level Completely by Yourself?
It is possible to self-study an A-level, but that does not mean it is the right approach for everyone.
A completely independent learner needs to identify the correct specification, source appropriate materials, plan the entire course and judge whether their work is reaching the required standard.
A structured online course can remove some of that uncertainty.
You still study independently, but you have a defined programme to follow rather than building the qualification from scratch.
Think particularly carefully about subjects where feedback is valuable. Essay-based subjects, for example, do not only require knowledge. Students also need to learn how to construct responses that satisfy the assessment objectives.
Being able to understand a topic and being able to produce an examination answer at A-level standard are related but different skills.
Independent learning should mean having control over when and where you study, not necessarily trying to complete the entire qualification without support.
How Do You Fit an Online A-Level Around School?
Give the subject a real place in your timetable.
One of the easiest mistakes is to treat an independently studied A-level as something you will work on whenever you have spare time. During a quiet week that may be manageable, but spare time tends to disappear quickly once school deadlines, assessments and revision begin accumulating.
Instead, establish regular study periods.
You might reserve particular evenings, weekend sessions or free periods for the online subject. The precise schedule matters less than making the time predictable.
You also need to account for your school subjects.
If an internal examination period is approaching, your workload may increase sharply. Planning ahead allows you to adjust your online study rather than simply abandoning it for several weeks.
The flexibility of online learning is most useful when it is paired with structure.
Will Universities Accept an A-Level Studied Online?
What matters is the qualification and your achievement rather than whether you prepared for it in a conventional classroom.
Online learning is the method of study.
Students still need to complete the formal assessments required for the relevant A-level, and those assessments determine the qualification they receive.
When researching university entry, concentrate on the institution’s stated qualification, subject and grade requirements.
If you are unsure about an unusual combination of school-based and independently studied qualifications, contact the university admissions team and explain your circumstances.
This is preferable to trying to predict how an institution will view your application.
The same principle applies throughout the process: verify the requirement rather than building plans around assumptions.
What If You Discover the Problem After Starting Year 12?
You may still have options, but timing matters.
Moving into a new subject becomes more difficult as the course progresses because you have an increasing amount of content to catch up on.
If you realise during the first few weeks that your chosen combination is wrong, investigate alternatives promptly. Our guide to changing an A-level after you have started covers the practical questions to consider.
Starting an additional online subject can offer more flexibility than joining a classroom course late because you are not necessarily tied to the same teaching timetable.
That does not make the missed content disappear.
You still need enough time before the examinations to cover the complete specification and develop the necessary assessment skills.
The later you begin, the more important a realistic study plan becomes.
How Should You Decide What to Do?
Start with the reason you want the subject.
If it is required for a university course you genuinely hope to pursue, finding another way to study it may be extremely worthwhile. If it is simply one of several subjects you would enjoy, an available alternative might be equally suitable and considerably easier to manage.
Then investigate the practicalities.
Check the specification, the workload, the assessment arrangements and where you could sit the examinations. Speak to your school about what support it can provide and make sure you understand how the additional study will fit around your existing A-levels.
Only then should you decide whether to enrol.
Your school’s timetable is an important part of your education, but it does not necessarily have to define its limits.
If the A-level you need is unavailable locally, online and independent study can provide another route. The key is to make sure that route works all the way from your first lesson to your final assessment.
