How Hard Is the DAT? A 2026 Difficulty Guide for Students
Wondering how hard the DAT really is? Most students find the Dental Admission Test moderately to very challenging. It is a demanding, fast-paced exam that tests six major subjects in a single sitting. With structured preparation and realistic practice conditions, students can significantly improve performance across all DAT sections.

What Makes the DAT Hard?
Breadth of Content
You are tested on Biology, General Chemistry, Organic Chemistry, Perceptual Ability, Reading Comprehension, and Quantitative Reasoning — all in one day.
Time Pressure
Finishing each section on time is one of the biggest challenges students report, especially for Reading Comprehension and Quantitative Reasoning.
Level of Detail
The DAT often tests conceptual understanding and application, not just memorization. You must recognize patterns and apply concepts quickly.
New Three-Digit Scoring Scale
As of 2025, DAT scores range from 200 to 600, with a national average around 400.
Competitive programs often look for scores above the national mean, depending on the school and applicant pool.
How Do Most Students Perform on the DAT?
Most students feel overwhelmed at first — and that is completely normal.
On the new scale, the average score is around 400, which represents the national mean. Competitive programs expect higher scores, but improvement is absolutely achievable with:
-
Consistent daily practice
-
Timed testing under real conditions
-
High-quality explanations and focused review
What Is the Hardest Part of the DAT?
Time Management
Many students struggle to finish Reading Comprehension and Quantitative Reasoning within the allotted time.
Perceptual Ability Test (PAT)
Most students have never encountered PAT-style visual reasoning before preparing for the DAT.
General Chemistry and Organic Chemistry
These sections require rapid recall, strong conceptual understanding, and familiarity with a wide range of topics.
Reading Comprehension
Passages are long and dense, requiring efficient reading strategies.
Quantitative Reasoning (Math)
This section is fast-paced, and mental math becomes difficult without regular timed practice.
How Can I Make the DAT Easier?
Start Early
Plan for 3–4 months of consistent preparation.
Practice Under Real Timing
Simulated, timed practice is one of the most effective ways to improve pacing and confidence.
Focus on Weaknesses
Real gains happen when you target the topics you avoid or struggle with most.
Use High-Quality, Realistic Practice Materials
Accurate questions and clear explanations matter far more than volume alone.
Find Support and Community
Studying with guidance and accountability helps students stay consistent and motivated.
How Hard Is the DAT Compared to Other Exams?
The DAT is challenging, but in a different way than exams like the MCAT or GRE.
-
The MCAT is longer and more passage-based.
-
The DAT is more fast-paced, more calculation-heavy, and tests six subjects in one sitting.
Students who practice consistently under real timing usually find the DAT manageable once they adjust to the pacing and question style.
Frequently Asked Questions
Is the DAT harder than the MCAT?
The DAT and MCAT are challenging in different ways. The DAT emphasizes science knowledge, math, and visual reasoning, while the MCAT is more passage-based. Neither exam is universally harder.
How many hours should I study for the DAT?
Most students spend 250–400 hours preparing over several months.
What is the hardest section of the DAT?
Many students struggle most with Reading Comprehension and Quantitative Reasoning due to strict timing. PAT is also challenging because it is unfamiliar to most students.
