About this exam

The Examen Integrado de Bioquímica is a comprehensive, multiple-choice assessment covering the full span of biochemistry as taught in health-science and life-science programs: biomolecular structure, enzyme kinetics, bioenergetics and carbohydrate metabolism, lipid and lipoprotein metabolism, amino acid and protein metabolism, molecular biology, gene regulation and cell signaling, clinical biochemistry, and integrated metabolic and laboratory reasoning. It suits students finishing a biochemistry course, candidates preparing for graduate or professional health programs, and professionals who want a structured check of retained knowledge across domains rather than a single-topic quiz. Because the exam is integrated, expect questions that connect pathways and clinical scenarios instead of asking for isolated definitions; the strongest preparation is active recall across pathways, followed by practice applying concepts to lab values and patient-style vignettes. Build a study plan weighted toward the domains that carry the most emphasis, but do not skip the smaller ones, since they are where well-prepared candidates often lose easy points. Review enzyme kinetics and regulation early, because those concepts recur throughout metabolism and molecular biology.

Common questions

About Examen Integrado Bioquímica preparation

What is the format of the exam?

Questions are multiple choice, with one best answer per item. Expect a mix of recall, pathway reasoning, and applied vignettes involving lab values or clinical scenarios. Because it is an integrated exam, individual items often require combining knowledge from more than one domain rather than recalling a single fact.

How many questions are on the exam, and how long do I have?

The official administering body publishes the current question count and time limit, and these can change between administrations. Check its website for the authoritative figures before you plan your pacing. Do not rely on numbers from older candidates or third-party forums, which are frequently out of date.

How difficult is the exam?

Difficulty is moderate to high for candidates who studied biochemistry passively. Straight recall items are answerable with solid course knowledge, but applied items separate candidates who can reason across pathways from those who memorized lists. Expect several questions where two answers seem plausible and the distinction lies in a regulatory or kinetic detail.

What is the passing score, and what does it cost?

Passing standards and fees are set by the official body and are published on its website. They are not fixed values you should assume from prior years. Confirm both before registering, and check whether any reduced-fee or institutional arrangements apply to your situation.

Can I retake the exam if I do not pass?

Retake rules, waiting periods, and any limits on attempts are determined by the official body and should be verified on its site. Plan as though a retake means a real delay: identify your weakest domains from your score report and rebuild them before scheduling again rather than repeating the same preparation.

In what order should I study the domains?

Start with biomolecular structure and enzyme kinetics, since regulation and metabolism build on them. Then work through carbohydrate, lipid, and amino acid metabolism as one connected map rather than three separate blocks. Add molecular biology and gene regulation next, and finish with clinical correlations and integrated laboratory reasoning, which draw on everything before them.

What are the most common failure modes?

Candidates most often lose points by memorizing pathways without understanding rate-limiting steps and allosteric regulation, by neglecting the smaller domains, and by misreading vignettes that hinge on one lab value. Another frequent problem is running out of time because they linger on calculation items instead of flagging and returning to them.

How should I prepare in the final weeks?

Shift from reading to retrieval: draw pathways from memory, explain regulation aloud, and work applied questions under timed conditions. Review every wrong answer to identify whether the gap was factual or reasoning-based. Keep one short daily review of enzyme kinetics and key regulatory enzymes, since those concepts appear across multiple domains.
