One Clear Path to Depth

One complete view of academic potential

Choose any DSA Concentration Subject and build your academic profile—one simple subject at a time.

The DSA Subject System

Every DSA subject follows one philosophy—depth over breadth—through a single Concentration Subject pathway.

What is a Concentration Subject?

Concentration Subjects are focused, advanced assessments in specialized areas of university study—such as Behavioral Economics, Molecular Biology, or Machine Learning—that show where a student can already engage with deep, concentration-level work.

How Subjects Are Scheduled

Each Concentration Subject is offered in one of four quarterly windows and examined once per year. Pick the subject and the window that fit your plan.

One Registration, A Configurable Academic Profile

  • One DSA registration gives you 6 exam attempts over 3 years.
  • Use them on any Concentration Subjects—repeat a subject or explore new ones.
  • Each subject allows up to 3 attempts; an unused attempt is never treated as a zero or incomplete result.
  • Every completed assessment receives its own 0–120 score.
  • Retakes draw from the same 6-attempt registration; attempts are tracked separately by subject.

Choose Your DSA Path

Start with the academic direction you want a university reader to remember.

If you know your intended major

Choose the Concentration Subject closest to that field and show depth where it matters most.

If you have two interests

Spread your 6 attempts across both—each subject stands on its own and builds a multifaceted profile.

If you are still exploring

Pick a subject you are willing to prepare for seriously. Depth and curiosity matter more than quantity.
