Choosing the wrong subjects early can lead to the worst A-Level subject combinations and block your future. Data from Lucy Cavendish College shows that 1 in 5 students fail to get into their top degree due to poor choices. Selecting the right subjects is your first step toward a successful university application.
Why Combinations Get Flagged
Admissions teams look for synergy between your subjects to ensure you are ready for degree-level work. Certain groups will flag your application because they lack the academic depth required by top schools.
- Overlapping Content: Taking subjects with very similar subject content, like Business Studies and Economics, is a disadvantage at universities like Warwick and LSE.
- Closed Doors: Poor combinations limit your future degree options. Lucy Cavendish College research found that 2 in 5 students would have chosen differently if they had received better advice.
While some subjects are fine on their own, they lose value when you group them with similar or non-academic choices.
Worst A-Level Subject Combinations to Avoid
Top university offices will flag combinations that lack variety or academic rigor. They prefer to see traditional subjects that prove you can handle a heavy academic workload.
- Business Studies + Economics: The Uni Guide notes that Warwick warns against the overlap in what you study, while LSE says this pair is “best avoided.”
- Multiple Applied or Vocational Subjects: Stacking choices like PE, Media Studies, or Textiles narrows your options, according to The Uni Guide.
- General Studies + Critical Thinking: These subjects do not count toward your standard entry offer at most top-tier universities, according to LSE’s A-Level subject guidance.
- Weak-Prep Combinations: Cambridge warns against using subjects like Art, Drama, or Media as part of your core “only three” A-Level choices, per cam.ac.uk.
Keeping a variety of traditional academic subjects is the best way to ensure university doors stay open.
Strategic Subject Alternatives
| Combination | Why It’s Risky | Take Instead |
| Business + Economics | Overlapping content | Economics + History |
| PE + Media Studies | Stacking vocational | PE + Biology |
| Accounting + Business | Non-preferred by LSE | Maths + Economics |
| Art + Drama | Lacks academic core | Art + English Lit |
You must check the academic rigor of your final three choices to stay competitive.
Are Soft Subjects Really Easier?
Many students struggle with the debate over “soft” versus “hard” A-Level subjects. You must understand how universities view these differences before you commit to a path.
- The Rigor Argument: A 2008 Durham CEM study showed that science subjects can be a full grade harder to master than Media or Drama (dur.ac.uk).
- The Counter-Evidence: However, research from the QCA found little evidence that “soft” subjects are actually less demanding for students (edu.rsc.org).
Regardless of how hard a subject feels, university preference is the ultimate measure of your future success.
Final Takeaway
Before finalising your subjects, check whether your choices could create one of the worst A-Level subject combinations for your intended degree. Teachwink’s Subject Combination Finder lets you enter your O Level or A Level subjects and instantly see which degree options they open up. If you’re a student in Pakistan or the Gulf, it’s the fastest way to check your combination before you’re locked into it.
