A Step-by-Step Guide to the AMCAS Application System 2025
You have spent years preparing for this moment. From completing prerequisite courses in biology and chemistry, to shadowing physicians, volunteering in hospitals, and engaging in meaningful research, the work you have already put in is significant. Now it is time to take everything you have done and package it into a medical school application that clearly communicates your passion for becoming a physician.
The American Medical College Application Service, commonly known as AMCAS, is the centralized platform used by most MD programs in the United States. Through one primary application, AMCAS sends your materials to the medical schools you select. Since every section plays a role in how admissions committees understand your academic abilities and personal readiness for medicine, it is important to understand each part before you begin.
This guide walks you through the entire AMCAS experience from registration to submission, offering insight, structure, and actionable tips for a smoother and more confident application journey.
AMCAS vs Other Medical School Application Portals
While AMCAS is the main system for allopathic medical schools, it is not the only system you might use. Some applicants also apply to:
- AACOMAS, which is required for DO medical schools
- TMDSAS, which is required for most Texas medical and dental schools
These portals are separate. If your school list includes DO or Texas programs, you will complete those applications in addition to AMCAS. Make sure to organize your deadlines in advance so you are not juggling multiple portals at the last minute. [1]
Getting Started: Registration and Preparation
Before you enter any application details, you will need to register on the AMCAS website using your AAMC account. If you already created an account to register for the MCAT, you will sign in using the same email and password.
Once you verify your identity, the AMCAS application dashboard will open. Spend a moment reviewing the layout so you understand what is required. The best way to avoid frustration is to prepare all necessary materials ahead of time, including:
- An unofficial transcript or record of your college coursework
- Accurate totals of extracurricular hours
- Contact information for recommenders
- A draft of your personal statement
- Your MCAT results or future testing date
- A payment method for processing fees
The fee structure is $175 for the initial school and $45 for each additional school added. Providing yourself time and organization from the beginning will help prevent mistakes later on.
Section 1: Identifying Information
This section collects your legal information and ensures all parts of your application can be properly linked. You will enter your full name, any previous names, birthdate, gender identity, birth country and city, and verification numbers that connect your MCAT and transcript records. Although simple, this section must be completely accurate. Even small errors can delay processing and verification.
Section 2: Schools Attended
Next, AMCAS asks you to identify every secondary and higher education institution you have attended. This includes your high school, your undergraduate university, community colleges if you took summer courses, and any programs for which you received academic credit, including study abroad semesters.
You will then be required to request official transcripts from each institution. These must be sent directly to AMCAS, not uploaded by you. Processing transcripts can take several weeks, especially during peak application months, so order them early. If you previously enrolled in any medical program, you must disclose that here and prepare to explain your circumstances later in secondaries or interviews.
Section 3: Biographic Information
Medical schools want to understand not just your achievements, but also the context in which you achieved them. This section allows you to provide important background information including:
- Permanent and local addresses
- Citizenship and residency status
- Race, ethnicity, and language proficiency
- Family education level and household income background
- Prior military service
- Any history of misdemeanors or felonies
- Whether you identify as disadvantaged due to economic or healthcare access
These details help admissions committees evaluate your application holistically. If you faced real barriers on your path to medical school, this is where you can identify that experience. Accuracy and honesty matter here. Schools appreciate transparency and clear explanations rather than incomplete responses.
Section 4: Coursework and Grades
This may be the most time consuming part of the entire AMCAS application. You must enter every course that counts toward your degree, including AP or IB credit if it has been applied to your college transcript. For each class, you will list the term, credit hours, whether there was a lab component, and the grade earned.
Once submitted, AMCAS uses this section to calculate multiple versions of your GPA, including overall, science, and year by year breakdowns. These standardized calculations allow medical schools to evaluate applicants fairly, regardless of institutional grading differences.
To avoid delays, work slowly and double check every entry. A missing lab course or incorrect grade can lead to verification issues that push your application behind schedule.
Section 5: Work and Activities
Here is where you bring your experiences to life. You may enter up to 15 activities that showcase how you have spent your time outside the classroom. These can include clinical experiences, volunteer roles, research positions, leadership involvement, employment, creative endeavors, and personal commitments. [3]
For each activity, you will describe your responsibilities, your impact, and the hours contributed. You also get to select up to three experiences as “Most Meaningful,” giving you extra characters to share deeper reflection.
Stronger entries focus on what you contributed and what you learned rather than listing tasks. Use this section to show curiosity, initiative, teamwork, and compassion. Admissions committees learn a lot about who you are through the experiences you choose to highlight.
Section 6: Letters of Evaluation
AMCAS allows you to centralize all recommendation letters in one place. You can include a committee letter, a letter packet from your premed advising office, or individual letters from supervisors, faculty, or physicians who know your character and strengths well.
Once you add recommenders and assign their letters to schools, AMCAS will notify them by email with instructions for submission. Request letters early. Strong recommendations take time to write, and you want them uploaded as soon as your application is verified.
Section 7: Selecting Medical Schools
At this stage, you will begin adding the medical schools to which your application should be sent. Your list should reflect a strategic range of programs that align with your GPA, MCAT performance, mission fit, and state residency. Most applicants submit to 25 to 30 schools, which helps maximize interview opportunities while keeping the process manageable.
Applying earlier in the cycle allows your file to be reviewed sooner and gives you more time to complete secondary applications.
Section 8: Personal Statement
In 5,300 characters or fewer, you will share your story and purpose for pursuing a career in medicine. [4] The best personal statements show reflection, growth, and a clear understanding of the realities of being a physician. Share experiences that genuinely shaped your commitment and explain how those moments prepared you to serve patients in the future.
Once you finalize your essay outside of AMCAS, copy it into the portal and review formatting before moving on.
Section 9: Standardized Tests
Finally, you will report your MCAT results, including section scores and dates of testing. Because MCAT scores are already stored in your AAMC account, this section often populates automatically. If you plan to retake the MCAT, indicate future testing dates so schools know more scores are coming.
Applicants who have taken other exams for dual degree programs, such as the GRE, may enter those scores as well.
Before You Submit
The AMCAS application is not something to rush. Review each part multiple times with fresh eyes. Once you certify and submit, your application will move into verification, where coursework details are checked against official transcripts. [2] This process can take several weeks depending on when you apply.
Submitting early in the cycle, ideally in June or early July, keeps you on the most competitive timeline for receiving secondary applications and interview invitations.
You have already put in the dedication and discipline required for medical school. Completing AMCAS is simply your chance to show admissions committees everything you have accomplished and the impact you are prepared to make as a future physician.
