How to Create a DAT or OAT Study Schedule That Works for You

I have worked with thousands of DAT and OAT students through the years, and one question I get asked over and over is:

What study schedule should I follow?

One of the biggest mistakes I see students make is trying to follow a study schedule created by someone else.

No one else knows your schedule. They don't know how many hours you have available each day, whether you're working or going to school, what subjects are your strongest and weakest, or exactly when you plan to take your exam.

I always encourage students to make their own study schedule. Build a schedule around your own circumstances and make it flexible enough that you can easily adjust it when needed.

A study schedule should be a guide. It should not become a deadline that forces you to take the DAT or OAT before you are ready.

Start With the Time You Actually Have

Before deciding how many weeks or months you need to prepare, look honestly at your own schedule.

A student taking a full course load has a very different amount of available study time than someone studying during a school break. A student working full-time has different demands than someone who can devote most of the day to DAT or OAT preparation.

Also consider your academic background.

Are Biology and General Chemistry strong subjects for you? Do you need substantially more work in Organic Chemistry or Math? Are you preparing for the DAT and need additional time for Perceptual Ability? Are you taking the OAT and need more time for Physics?

Your study schedule should reflect your strengths, your weaknesses, and your available time.

That is why there is no single DAT or OAT study schedule that is right for everyone.

Build a Schedule That Can Change

Your original study plan is exactly that—a plan.

Things happen. A difficult week at school, work responsibilities, illness, family obligations, or simply discovering that a subject requires more work than you expected can put you behind.

That doesn't mean your preparation has failed.

Adjust the schedule.

If Organic Chemistry takes longer than you anticipated, give it more time. If Biology is progressing faster than expected, you may be able to shift some of that time elsewhere.

The purpose of your schedule is to help you prepare for the exam. The purpose is not to finish every topic by an arbitrary date just because you wrote that date on a calendar several months earlier.

What Should You Do If You Fall Behind?

This happens to many students.

The worst response is often trying to cram additional material into every remaining day simply to get back to the original schedule.

Instead, reassess.

Ask yourself:

• What have I completed?

• What still needs substantial work?

• Which subjects are weakest?

• Am I understanding the material or simply trying to get through it?

• Do I realistically have enough time remaining before my scheduled exam?

Then adjust your plan.

Moving your timeline is better than rushing through important material just to say you completed your schedule.

Your Test Date Should Work With Your Preparation

Another common mistake students make is becoming so committed to a predetermined timeline that they take the DAT or OAT before they are fully prepared.

I understand why this happens. Students have application deadlines, school schedules, jobs, vacations, and other responsibilities. Once an exam date is on the calendar, it can begin to feel permanent.

But your test date should work with your preparation—not dictate it.

Of course, you need to consider application deadlines and testing availability. But if your preparation clearly shows that you are not ready, taking the exam simply because that was the date on your original study schedule is not a good reason to sit for an important exam.

Signs You May Not Be Ready for Test Day

How do you know when you actually need more preparation time?

Here are several warning signs:

Inconsistent practice performance — If your performance fluctuates significantly and you cannot consistently demonstrate mastery of the material, your preparation may not yet be stable enough.

Major content gaps — If there are entire subject areas you have not reviewed or genuinely do not understand, you need more preparation.

Weak areas that have not improved — If you identified weak subjects early in your preparation and they remain weak, don't ignore them simply because test day is approaching.

You are memorizing without understanding — Memorization certainly has a place in DAT and OAT preparation, but you also need to understand concepts well enough to apply them to unfamiliar questions. If you are trying to memorize your way through material you don't understand, spend more time learning the underlying concepts.

The goal isn't simply to finish studying.

The goal is to be prepared.

DAT vs. OAT Study Schedule Considerations

The DAT and OAT overlap in several important areas, but they are different exams. Your study schedule needs to reflect those differences.

DAT Students

DAT preparation includes:

• Biology

• General Chemistry

• Organic Chemistry

• Perceptual Ability

• Reading Comprehension

• Quantitative Reasoning

The Perceptual Ability Test (PAT) requires its own preparation. Don't leave PAT practice until the end of your study schedule. Skills in this section benefit from consistent practice over time.

OAT Students

OAT preparation includes:

• Biology

• General Chemistry

• Organic Chemistry

• Physics

• Reading Comprehension

• Quantitative Reasoning

OAT students need to account for Physics when building their schedule. Don't underestimate the amount of time you may need for Physics, particularly if it has been a while since you completed the course or it was not one of your strongest subjects.

Whether you are taking the DAT or OAT, use current preparation materials that reflect the exam you will actually be taking.

Use a Structured Schedule as a Framework, Not a Rule

There is nothing wrong with starting with an established study schedule. In fact, having a framework can make a large amount of material feel much more manageable.

The mistake is assuming you must follow someone else's schedule exactly.

For students looking for a starting point, we also provide [ Free DAT and OAT Preparation Resources from Dr. Jim Romano].

DAT students who want a more structured starting framework can also review our [ 3-Month DAT Study Schedule] and adapt it to their individual needs.

If a structured framework fits your situation, use it. If you need four months, five months, or a different daily structure, adapt it.

The schedule should work for you. You should not be working for the schedule.

Prepare With the Highest Goal in Mind

For DAT students, I tell them to prepare with the goal of a 600.

For OAT students, aim for a 400.

Will most students achieve the maximum score? Of course not, and you certainly do not need a perfect score to be successful.

But your goal during preparation should always be to do the very best you possibly can.

Preparing with the highest goal in mind means not intentionally cutting corners, skipping difficult material because you don't like it, or deciding that something is "good enough" when you know you still have time to improve.

Where your final score lands is one thing.

How well you prepare is something you can control.

The Goal: Prepare to Take the Exam Once

The goal should be to prepare to take the exam one time and walk into the testing center fully prepared.

Don't let someone else's calendar determine when you're ready.

Build your own schedule. Adjust it when necessary. And take the DAT or OAT when your preparation tells you that you're ready—not simply because a study schedule says it's time.

Hope this helps.
