Medicine and health

Medicine

The longest, most tightly gated undergraduate degree there is, and the one whose entry requirements are decided at fifteen. Almost everything else on this page follows from chemistry.

How long: Five to six years undergraduate outside North America; four years of medical school after a first degree in the US and Canada. Then residency, which is where the real length is.

What you actually study

As opposed to what the name suggests.

Two to three preclinical years of anatomy, physiology, biochemistry, pharmacology and pathology — volume of memorisation on a scale nothing at school prepares you for.
Three or more clinical years spent in hospitals and clinics rather than lecture theatres, rotating through specialties.
Communication, ethics and law, which students dismiss until the first time they have to deliver bad news.
Evidence and statistics, because reading a trial correctly is a clinical skill and most doctors are worse at it than they think.
Increasingly, population health and health systems — the part that explains why the same illness has different outcomes in different postcodes.

The hardest part

Not the intellectual difficulty, which is real but manageable, and not the exams. It is the duration and the compounding: six years of degree, then residency, during which your friends in other fields buy houses and you are still being examined. The people who struggle are rarely the least clever ones — they are the ones who chose it at seventeen for someone else's reasons and had no answer when it stopped being interesting.

What you need to get in

By school system. Requirements are set by individual universities and change — confirm on the course page for the year you apply.

Saudi curriculum track

requiredمسار الصحة والحياة — Health and Life Sciences

The only track that leads to a Saudi health college. Admission is then the weighted composite of secondary GPA, Qudurat and Tahsili, with Tahsili often weighted heaviest — so the science paper matters more than your school report does.

A-Level

requiredChemistry · Biology

helpsMathematics · Physics

Chemistry is required at nearly every medical school that names a subject. A minority accept chemistry plus any second science; almost none accept a candidate with neither chemistry nor biology. Grades are typically at the top of the scale, and they are not negotiable in the way other courses' are.

IB Diploma

requiredChemistry HL · Biology HL

helpsMathematics: Analysis and Approaches SL or above

Standard Level chemistry is rejected by most medical schools. A typical offer is 36–38 points including 6 or 7 in both science HLs, which usually means using the Group 6 slot for the second science.

Advanced Placement

helpsAP Biology · AP Chemistry · AP Calculus AB or BC · AP Statistics · AP Physics 1

In the US medicine is a graduate degree, so APs feed the pre-med bachelor's rather than medical school itself. Note the trap: many medical schools will not accept AP credit in place of the required university biology, chemistry and physics sequences, so taking the credit and skipping the course can leave you without the prerequisite four years later.

IGCSE

Separate sciences rather than Combined Science, and strong grades in English and mathematics — UK medical schools commonly screen at grade 6 or 7 across the board before looking at anything else.

Tests and other gates

UCATJuly–September of the application year
Required by most UK medical and dental schools, and several rank applicants on it directly. Booking closes in September, weeks before the mid-October application deadline.
Tahsili (science)End of Grade 12
Frequently the heaviest single component of the Saudi health-college admission composite.
QuduratFrom Grade 11
Sit it early; the best score counts and an early attempt is diagnostic.
MCATAfter two or three years of a US bachelor's
The US graduate-entry route. Nothing you do at seventeen prepares for it directly, and it is worth knowing the road has this on it.

What closes this door

Without chemistry at A-Level or HL, medicine is closed at almost every university that states a subject requirement, and it cannot be picked up later.
Combined Science at IGCSE often blocks entry to A-Level chemistry, which closes medicine two years before you apply to it.
Missing the UCAT registration deadline ends the UK application for that year entirely — there is no late route.

Where it leads

Careers written up on this site, and the reason each one follows from this degree.

General Practitioner
The largest destination by a wide margin, and the shortest route to independent practice.
General Surgeon
The longest training of the common routes, and the one most students picture.
Anesthesiologist
Physiology and pharmacology under time pressure, with the best hours-to-pay ratio in hospital medicine.
Emergency Physician
Undifferentiated patients, shift work, and decisions made without the full picture.
Psychiatrist
The specialty with the least competition for entry and among the most unmet demand.
Radiologist
Diagnosis through imaging, with almost no direct patient contact.
Epidemiologist
A common move out of clinical practice and into disease at population scale.
Policy Analyst
Health policy, regulation and system design, where a clinical background carries real weight.

What it is not

That medical school is the hard part. Getting in is competitive and finishing is demanding, but the specialty training afterwards is longer than the degree and much more competitive at the top end.
That you must decide a specialty early. You do not, and almost nobody's final specialty is the one they named at eighteen.
That it is the only way to work in health care. Nursing, pharmacy, physiotherapy, radiography and paramedicine all reach patients in a third to a half of the time, and this site exists partly to say so.

In Saudi Arabia

Medicine is the highest-status degree in the Kingdom and admission is arithmetic: secondary GPA, Qudurat and Tahsili combined into a composite, ranked, and admitted until the seats run out. There is no personal statement and, for most programmes, no interview — nothing about you that is not in the composite is considered. Studying abroad is common and adds a step: SCFHS classification and, in many cases, examination before you can practise here, so check that the specific medical school is recognised before enrolling rather than after graduating.

Consider instead

Same interest, different trade-off — the most useful section on this page and the easiest to skip.

The parts that go out of date

Entry requirements are the fastest-moving information on this site. These are the statements most likely to have changed.

Which medical schools accept chemistry plus a non-biology second science changes, and is stated per course rather than nationally.
UCAT weighting differs sharply between medical schools and is republished every cycle — applying to four that all rank heavily on it with a middling score is a common way to collect four rejections.
Saudi health-college admission weightings are set per university per year.

Where this came from

Admission patterns stated by UK medical schools through UCAS, by Saudi health colleges through the national admission composite, and by US medical schools through the graduate-entry pre-med structure. Individual courses vary and must be checked directly.
