MCAT Sample Questions
In order to provide you with a better understanding of MCAT practice questions, we have provided you with a quick overview of some MCAT example questions. We have provided some examples from different sections that are tested on the MCAT.
MCAT Practice Question #1
Category: Biological and Biochemical Foundations
Question: A scientist using mouse models to determine the response of blood hormones to large levels of glucose in the body discovers a new hormone not previously described.
According to his data, this hormone is found both inside and out of cells when carrying out its function, increase the amount of nucleic acid in the cell while functioning, and are derived from a structure containing four hydroxycarbon rings.
This will likely be categorized as which type of hormone?
- Amino Acid
Answer: B. Steroid hormones, derived from cholesterol, act on intracellular receptors and produce mRNA specific to the outcome they produce. Thus, they are found both inside and out of the cell.
Peptide hormones, such as insulin, act on outer membrane receptors, but are polarized, so they cannot enter the cell. Amino acid hormones can have the ability to enter the cell, but are usually made up of very small combinations of amino acids, and never of cholesterol, a four hydroxycarbon ring.
MCAT Practice Question #2
Category: Chemical and Physical Foundations
Question: One of the many reasons that the eukaryotic cell can possess so much information in its DNA is the ability to condense coding regions when they are not being expressed. When acting on DNA, which of the following processes will usually lead to a decrease in gene expression?
- Increased histone acetyltransferase activity
- Decrease in histone deacetyltransferase activity
- Increase in methylation activity
- Increase in heterochromatin:euchromatin ratio
Answer: C. This is a straightforward question that assesses knowledge of modification of DNA segments. Although in the real world these methods are not exclusive to increasing or decreasing activity, for MCAT testing purposes, histone acetyltransferase (HAT) frees DNA from histone proteins for expression.
Histone deacetyltransferase (HDAC) binds DNA more tightly to histone, creating more heterochromatin, which is not expressed. Methylation is an epigenetic modification that generally trends toward silencing gene expression.
MCAT Practice Question #3
Category: Psychological, Social, and Biological Foundations
Question: A patient comes into the ER looking extremely agitated. They are acting aggressive, and claiming they need medication or “bad things will happen”. What is the likely state of this patient’s dopamine system?
- There is decreased dopamine in the synaptic cleft.
- There are decreased dopamine receptors on the post-synaptic membrane.
- There is cell death in the areas with high dopamine cells.
- There is seizure-like activity in the dopamine brain areas.
Answer: B. This question comes off much like a biology question, but is actually a first-level derivative of a psychology/behavior question testing the concept of tolerance. Long-time stimulant drug users have excessive amounts of dopamine in the synaptic cleft due to inhibition of re-uptake.
Because of this, the body responds by decreasing the amount of available receptors. This leads to tolerance, or the individual needing more drug to maintain the same level of physiological response. A person in withdrawal likely has a high tolerance built up over an extended period of drug use.
Which Practice Test is Best for MCAT?
There are plenty of MCAT practice test options available for students. However, not all MCAT practice is created equally. All of the MCAT test questions and diagnostic tests listed above are great resources to start out with.
Since there are 4 sections on the MCAT, it is important to make sure your MCAT practice test includes questions that cover all 4 sections. Within those 4 sections, there are also various topics that you should ensure you are tested on.
The best MCAT practice tests will include MCAT sample questions on all topics. You can review those topics below to ensure your practice exam includes them.
|Biological and Biochemical Foundations||Chemical and Physical Foundations||Psychological, Social, and Biological Foundations||Critical Analysis and Reasoning|
|General Chemistry||General Chemistry||Sociology||Reasoning Beyond the Test|
|Organic Chemistry||Organic Chemistry|

Is the MCAT Exam Difficult?
The MCAT is generally considered a very difficult exam. There are numerous subjects tested on this exam and MCAT test questions tend to make you think more than other standardized exams like the SAT or ACT.
The timing aspect of this exam also makes this exam more challenging. In total, you will have 2 hours and 55 minutes to complete the 215 MCAT questions. Students should ensure they have taken numerous MCAT practice tests to get acclimated with the timing before taking the actual exam.
You can read our complete guide on how hard is the MCAT for more information.
How Many Practice MCATs Should I Take?
The number of MCAT practice tests you take should depend on how you are progressing through your studies. However, many students may end up taking between 4 and 6 full-length MCAT practice tests when it is all said and done.
Many students may follow a similar path to the following:
- Practice Test #1 – This should be your “diagnostic test.” This should be taken before any studying is done. This will help you get a gauge of where you are at. This will help you track your progress.
- Practice Test #2 – This should be taken about 25% through your studies.
- Practice Test #3 – This should be taken about 50% through your studies.
- Practice Test #4 – This should be taken about 75% through your studies.
- Practice Test #5 – This should be taken when you finish your studies.
- More Practice Tests – These should be taken until you are comfortable with the material and the timing aspect of the exam.
