When Should I Start Studying for the DAT?

Preparing for the Dental Admission Test is one of the biggest steps on your dental school journey. A common question students ask early in the process is: When should I start studying for the DAT, and how long should that preparation last?

There is no single answer and your best start date depends on your academic background, classes,  personal life, and how ready you are to handle content review and practice tests without burning out. One key piece of advice is to plan your DAT prep around your classes and other commitments, so you have sufficient time for both coursework and effective studying.

In this guide, we will walk through when to start studying to take the DAT, how long most students study, how to build a realistic study schedule that supports strong DAT scores on test day, and some other study tips. The best advice is to begin light prep in April of sophomore year and plan to take the exam about a year before you plan to start dental school. That gives you time to retake the test if needed and do plenty of focused practice tests during the summer which keeps your score aligned with your application cycle.

No matter which path you choose, we recommend taking the DAT when your prerequisite courses are mostly complete and your study plan feels realistic. A support system, whether that is study groups, mentors, or friends, can also make it easier to stay consistent during DAT prep. Additionally, following the provided DATBooster study schedule for the DAT can help you stay on track!

I. DAT Format Overview

Understanding the DAT Format

The DAT contains four sections: Survey of Natural Sciences, Perceptual Ability Test (PAT), Reading Comprehension, and Quantitative Reasoning. The Survey of Natural Sciences section includes 100 questions, 30 from chemistry, 30 from organic chemistry, and 40 from biology with a 90 minute time limit. The Perceptual Ability Test includes 90 questions across six areas with a 60-minute limit. For Reading Comprehension, you will see three passages with 50 questions in 60 minutes, so timed reading practice is not optional. Quantitative Reasoning includes 40 questions in 45 minutes. 

Each section tests different skills, from basic sciences like organic chemistry and biology to perceptual ability, time reading, and problem solving. Knowing the section breakdown helps you plan time studying, stay on point, and spend a significant amount of time on your weaknesses.

Using official resources like the American Dental Association to understand the real DAT format provides information and materials that help you confirm what is actually tested. Pair that with a structured DAT prep resource so your practice is consistent and targeted. Having one resource, such as DATBooster, which has practice exams, PAT practice, as well as videos and notes is incredibly useful for this! This will increase your academic readiness for the DAT.

II. Getting Ready for DAT Prep!

How Long Should You Study Before You Take the DAT?

When deciding on your test date, consider your academic schedule, personal life, and your dental school application cycle. Many students choose to take the DAT before their dental school application opens, which is usually in May or June. Since the DAT is offered year round, you can pick a date that fits your schedule, but register early because seats can fill. The lates one can take the DAT is during the spring semester of the year you are applying to dental school.

Most students need a minimum of three months of dedicated study time. A common baseline is three hours a day, five days a week, which adds up to enough study time for content review, practice, and breaks. Your study schedule should cover the basic sciences, build perceptual ability with PAT work, and improve reading comprehension and quantitative reasoning through timed drills and practice tests.

In the few weeks before test day, shift more of your time toward what drives score gains: targeted review of weak areas and full length practice tests under timed conditions. If your practice is realistic, test day feels routine instead of stressful. That said, three months is an average, not a rule. The key factor is the total number of high quality study hours you can reliably complete. This means avoiding overloading your study schedule and forcing DAT prep during a difficult semester. 

Since the DAT exam is offered year-round, you can choose a test date that fits your plan instead of forcing an unrealistic window. It is recommended to register 60 to 90 days in advance. And Taking the DAT early enough in your pre-dental timeline also gives you space for a retake if needed. 

Recommended Courses Before Starting DAT Prep

Before beginning DAT prep, it helps to have completed the core science courses tested on the DAT exam. If you already have these classes done, content review becomes faster and your study schedule can shift earlier toward practice tests.

Strongly recommended courses:

• General Biology I and II
• General Chemistry I and II
• Organic Chemistry I and II

Helpful but not required:

• Physiology
• Biochemistry
• Microbiology
• Immunology
• Embryology

A solid base in biology and the other basic sciences matters because the DAT covers a wide range of material. Many students aim to complete at least 80% of prerequisites before they take the DAT so the exam feels like review, not brand new learning. Additionally you may integrate DATBooster notes and Anki cards to make your life easier and save time when it comes to note taking. 

III. Different Timelines for DAT Prep 

Starting DAT Prep During a College Semester

Many students begin studying during a college semester, especially if they want to apply to dental school without multiple gap years. One advantage of studying during the semester is that summer can stay open for shadowing, volunteering, or research. Those experiences strengthen your dental school application alongside strong DAT scores. 

The challenge is balancing classes with DAT prep. For most students, a three to four month study schedule with a reduced course load fits well here. A common strategy is to study steadily through the spring semester and set test day two to four weeks after finals. That final stretch gives you focused time for full length practice tests and review without daily class pressure. 

Remember, it is okay to take a gap year if you feel overwhelmed, just make sure you adjust your test date so your DAT score is valid for your application cycle. Additionally, support matters. Study groups, mentors, and friends can help you stay accountable and manage stress during the semester.

Starting DAT Prep During the Summer Between Semesters

Studying during the summer between semesters is another popular option because it allows for a concentrated routine. With fewer academic obligations, you can increase daily study time, take more practice exams, and adjust your plan quickly based on performance. The downside is that this approach can limit work or volunteering. That tradeoff may be worth it, but you should plan around your application cycle. 

Some students try to take the DAT after only two months of summer studying, but many benefit from starting light review late in the spring semester. That way, you still get roughly three months total, and the final few weeks can focus on practice tests and high yield review. 

A study schedule can help you structure the summer so you hit every topic without drifting. This is also a good time to sharpen test taking strategies and build stamina through full length practice tests. DATBooster has custom lecture and solution videos made by highly experienced tutors to help you with your weaknesses!

Starting DAT Prep After Graduation While Working

This path is common for students taking a gap year, career changers, and other nontraditional applicants. Studying while working full time usually requires a longer timeline and stricter planning. As an example, if you wait until after senior year or graduation to take the DAT, set your test date based on when you want to start dental school. That timing affects your application cycle and score validity.

Because weekday hours are limited, many students in this category plan for four to five months of DAT prep before they take the DAT. Studying often happens in the evenings and on weekends, so consistency matters more than intensity. Students feel most prepared right after junior year, while the basic sciences and quantitative reasoning are still fresh. Burnout is the biggest risk, which is why it is important to be realistic, take breaks, and avoid studying right before the test so you have time for targeted review and practice tests. Remember, you can take the DAT a maximum of three times without needing special permission.

IV. DAT Schedule and Final Thoughts

What Should Your DAT Study Schedule Include?

Regardless of when you start, an effective DAT study schedulerequires content review, regular practice tests, and targeted review of weak areas to increase score. You should never skip any of these phases. Moreover, practice tests let you spot trends, fix pacing, and refine strategies. These especially help build endurance and improve performance across quantitative reasoning, reading comprehension, and perceptual ability. Combining this with targeted review will allow for the strongest possible DAT score for you with much time saved! 

Final Thoughts

When you start studying for the DAT matters, but how you study matters more. Most students do best with about three months of focused DAT prep, adjusted based on school, work, and personal life. Because the DAT is offered year-round, you can choose a test date that supports strong performance and application success. Whatever timeline you pick, use DATBooster and all its corresponding resources to ensure that your studying is focused on your weaknesses! 

If you want a higher final score, prioritize a realistic study plan, steady practice tests, and targeted review in the few weeks before test day. Do that, and you will give yourself the best chance to earn the DAT score you need to get into your dream dental school.
