The SPLE blueprint is four domains with fixed weights: Basic Biomedical Sciences 10%, Pharmaceutical Sciences 35%, Social, Behavioral and Administrative Sciences 20%, and Clinical Sciences 35%. Those four numbers are the single most useful planning tool you have, and most candidates use them only to decide that "clinical is the big one" before returning to whatever they were revising anyway.
Every figure in this guide is checked against the official SCFHS source linked below - last verified 13 September 2026.
Clinical Sciences - 35%
This is pharmacotherapy across the organ systems, and it is the largest single block along with Pharmaceutical Sciences. Expect cardiovascular, respiratory, endocrine and diabetes, infectious disease and antimicrobials, gastrointestinal and renal, and central nervous system, pain and psychiatry. Alongside the system-by-system material sit the cross-cutting topics: dosing in special populations, patient assessment and laboratory values, over-the-counter and self-care advice, and patient counselling.
The questions that separate candidates here are rarely "what is the mechanism of X". They are scenario items where two options are pharmacologically defensible and one is right for this patient - the renally-impaired one, the pregnant one, the one already on an interacting drug. Practise reading the stem for the constraint before you read the options.
Pharmaceutical Sciences - 35%
The other 35%, and the wider of the two in scope. It runs from medicinal chemistry, drug classes and mechanisms, adverse effects and interactions, toxicology and pharmacognosy, through pharmacokinetics and pharmacodynamics, to the formulation side: dosage forms, stability and biopharmaceutics, dosage and intravenous calculations, dilutions and compounding, and sterile technique.
Calculations deserve separate treatment. The arithmetic is almost never difficult. Setting the problem up quickly is the skill, and it decays fast without practice. At roughly 72 seconds per question, a calculation you have to reason out from first principles costs you two questions' worth of time, not one. Drill dosing, dilutions, infusion rates and compounding until the setup is automatic rather than reasoned.
Social, Behavioral and Administrative Sciences - 20%
This is the domain that decides borderline results, and the reason is structural: it is Saudi-specific. It covers Saudi pharmacy law and regulation, professional ethics and SCFHS classification, the Saudi health system and the Vision 2030 reforms, public health and the national immunisation schedule, pharmacoeconomics, dispensing and pharmacy informatics, and medication safety and error prevention.
You cannot revise any of that from an international pharmacy textbook, and you cannot safely substitute another country's rules. A pharmacist who has practised elsewhere will have confident, specific and wrong answers about scheduling categories, prescription validity, establishment licensing and pricing rules, because those are exactly the topics where every jurisdiction differs in detail while sounding similar in outline.
Twenty per cent is forty questions. That is the difference between a comfortable pass and a resit, and unlike the clinical domains it can be closed in weeks rather than months, because it is finite: a defined body of regulation, a defined schedule, a defined set of ethical duties.
Basic Biomedical Sciences - 10%
Physiology and pathophysiology, biochemistry, microbiology and immunology, and the genetics and pharmacogenomics underneath the clinical material. Twenty questions.
The temptation is to skip it. Don't, but do not over-invest either. Most of what this domain tests is reinforced by the clinical revision you are doing anyway - understanding why a drug works on a particular receptor in a particular tissue is simultaneously Basic Biomedical and Clinical preparation. Treat it as the foundation you revise through the clinical domains rather than as a separate syllabus, and spend the saved time on the Saudi-specific block.
Turning weights into a study plan
Three rules make the blueprint actually change what you do.
Plan in questions, not topics. Ten per cent sounds dismissible; twenty questions does not. Forty questions of Saudi law and health system sounds like what it is - a serious block of marks sitting in the most closable domain on the paper.
Measure by domain, not overall. A single percentage hides the shape of the problem. Two candidates at 68% can need entirely different months of work, and only a per-domain breakdown tells them which.
Revise the 20% disproportionately early. The clinical domains reward sustained work over months; the Saudi-specific domain rewards a concentrated few weeks and then holds. Doing it early means it is banked while you are still grinding pharmacotherapy, rather than crammed in the week before a test date you have already paid for.
Common questions
Are the domain weights fixed for every sitting? The published blueprint gives these weights, and both parts of the paper draw on the same blueprint. Confirm the weights in the current applicant guide before planning around them.
Which domain should I start with? If you are internationally educated, start with the Saudi-specific 20% - it is the one that will not improve by accident. If you trained in Saudi Arabia, start with whichever of the two 35% domains your diagnostic is weaker in.
How much detail does the law material go into? Enough that generic answers fail. The topics are specific: establishment licensing, prescription and dispensing rules, controlled-drug handling, pricing, pharmacovigilance and data protection, and the duties set out for pharmacists in the healthcare professions law.
Format, pass score and attempt rules are covered in the SPLE exam guide.
