Parents weighing the IB Diploma against A-Levels ask "how hard is it really?" The honest answer is best given in hours, not adjectives. The IB Diploma demands roughly 30 to 38 hours of academic work per week outside scheduled school hours — equivalent to a part-time job on top of a full school day. Some students manage this comfortably and finish at 38-42 points. Others struggle and end at 28-32. The difference is rarely talent; it is workload tolerance and time-management.
A typical IB Diploma student's weekly hours, by component:
Six subjects — 4-5 hours per HL subject (three subjects = 12-15 hours), 2-3 hours per SL subject (three subjects = 6-9 hours). Total: 18-24 hours.
TOK — 1-2 hours weekly across both years for reading, presentation prep, essay drafting. 1-2 hours.
Extended Essay — 30-50 hours total spread over 6-9 months. Averages out to 1-2 hours weekly.
CAS — 2-4 hours weekly for activities and reflection. 2-4 hours.
Internal Assessments (IAs) — periodic intensive bursts in the IA cycle for each subject. Averages out to 3-5 hours weekly.
Past-paper practice in the run-up to exams. 3-5 hours weekly increasing in DP2.
Total: roughly 30 to 38 hours per week outside school hours, with significant variation by week (IA deadlines, EE drafting, mock exams).
Compared To A-Levels
An A-Level student taking three subjects typically does 18-25 hours per week of out-of-school academic work. A student taking four A-Levels does 25-32 hours.
So:
Three A-Levels: 18-25 hours weekly.
Four A-Levels: 25-32 hours weekly.
IB Diploma: 30-38 hours weekly.
The IB Diploma is roughly equivalent in workload to four A-Levels with extras. Over two years, total academic hours are broadly comparable to four A-Levels including Further Maths — but the IB spreads them differently and adds the core (TOK + EE + CAS) which doesn't have a direct A-Level equivalent.
The IA Cycle — Where The Hours Burst
Internal Assessments (IAs) are coursework pieces in each subject — typically 1,200-2,500 words plus analysis/exhibits. They contribute 20-25% of each subject's final grade. The IA cycle pattern:
Topic selection — 1-2 weeks per subject.
Research / data collection — 2-4 weeks per subject.
Drafting — 2-3 weeks per subject.
Revision and final draft — 1-2 weeks per subject.
Submission deadlines — usually staggered across DP1 and early DP2.
During IA bursts, weekly workload can spike to 40-50 hours. Students who plan IAs early in DP1 and stagger them avoid the worst spikes; students who leave them late get crushed.
Who Copes With the IB Workload
The students who consistently finish the IB at 38+ points share five traits:
Strong time management. They plan weekly schedules and stick to them. IAs are blocked into the calendar months in advance.
Genuine interest across multiple subjects. Six subjects is not a burden if you actually like five of them.
Resilience to deadline pressure. The IA cycle means three or four major deadlines clustered around the same weeks. Resilient students batch the work.
Strong writing fluency. The IB rewards extended written argument across many subjects plus TOK and EE. Slow writers spend longer on every piece.
Family support that protects study time. The IB rarely works without 30+ uninterrupted hours per week. Families that protect this time produce stronger outcomes.
Who Struggles With the IB
Equally honest — students who struggle on the IB typically share one or more of:
Workload-sensitive temperament. Students who get overwhelmed by simultaneous deadlines do better with three deeper A-Levels than six broader IB subjects.
Strong specialisation but indifference to breadth. A future mathematician who hates languages and arts is mis-served by mandatory language acquisition and arts/elective requirements.
Heavy extracurricular commitments. Serious sport, music conservatoire-style training, or other intense extracurriculars compete with the 30-38 hours the IB demands.
Slow writing or English-as-additional-language struggle. The IB has more extended writing than A-Levels. EAL students with weaker English writing find the workload harder.
Weak time-management coming into DP1. The IB rewards planning. Students who can't plan their week find IAs and EE arriving late.
How To Manage the Workload
Practical strategies that work:
Plan the IA calendar in DP1, not DP2. Map all six IA deadlines onto one calendar. Block out 4-6 weeks before each.
Start the EE in DP1. First draft by end of DP1 means DP2 is for refinement, not creation. See Extended Essay guide.
Treat TOK seriously. Many students leave TOK until DP2 and lose bonus points. Start the essay planning in DP1.
Use weekends strategically. Most IB students do 8-12 hours of academic work on weekends. Plan it; don't drift into it.
Get help early in HL subjects. If a HL subject is sliding from 7 to 5, fix it in DP1 with focused tutoring. Recovering in DP2 is much harder. See IB Diploma tutoring.

The IB Diploma demands roughly 30-38 hours of academic work per week outside school hours — equivalent to a part-time job. Six subjects (three HL + three SL), TOK, Extended Essay and CAS combined. About 80% of candidates earn the Diploma each year; the global average score is around 30 points out of 45. Workload is more demanding than three A-Levels but comparable to four A-Levels with the core added.
Typically 30-38 hours per week of academic work outside scheduled school hours, with significant variation by week (IA deadlines, EE drafting, mock exams can spike to 40-50). Three HL subjects take 12-15 hours; three SL subjects 6-9; TOK 1-2; EE 1-2 averaged; CAS 2-4; IAs 3-5; past papers 3-5.
Heavier rather than harder per subject. Three A-Levels demand 18-25 hours weekly; four A-Levels 25-32; the IB Diploma 30-38. Per-subject content depth at IB HL is comparable to A-Level depth. The IB demands more breadth (six subjects vs three or four) plus the core (TOK, EE, CAS). Students with strong time management cope; those without struggle.
Three common answers from students: the IA cycle (six pieces of major coursework with deadlines clustered together in DP1), the Extended Essay (a 4,000-word independent research piece that students often underestimate), and Maths AA HL specifically (the most demanding HL subject for many students). The mandatory breadth — having to engage with subjects outside one's strongest area — also frustrates specialisation-strong students.
Students who are workload-sensitive and get overwhelmed by simultaneous deadlines; students with clear specialisation in one discipline who are indifferent to breadth; students with very heavy extracurricular commitments (elite sport, conservatoire-style music) that compete with 30+ hours of weekly study; students with weak English writing fluency if English is not first language and the extended writing is a barrier. For these students, three A-Levels done well usually produces a stronger application than the IB done at moderate scores.
Yes — about 20% of candidates each year either don't earn the full Diploma or earn it at a low score (24-28) that limits university options. Common patterns: missed IA deadlines that cap a subject grade; TOK or EE submitted late or at D grade; multiple subjects below 4 because preparation was spread too thin. Most of these are workload-management failures, not ability failures.
