One student, two apps.
- The student
- A high-school student getting ready for the SAT
- The test app
- A maths test they took at school last week
- The tutoring app
- An app they're opening for the first time today
All three are made up, and so is every number below.

1
The test app watches the student work.
The student answers 16 algebra questions in a timed test. Now the test app knows how each question went, including a few things nobody outside it should see.

Private details stay behind. Only the facts leave.
A small piece of Seneca software runs inside the test app. Before anything leaves, it sorts what the test app knows. Facts go out. The student's name is swapped for a code. The questions, the answers and the name stay where they are.
Leaves the test app
- Right or wrong, per question
- Time spent
- Whether a hint was used
- The topic
- The student, as a code:
lrn_2261…
Stays in the test app
- The student's name
- Their school grade
- The questions
- The student's answers

Seneca files it, and keeps three things apart.
What happened, what the test app thinks about it, and what Seneca reads from it are stored separately, so nobody mistakes an opinion for a fact. Here is one topic:
What happened
4 questions on systems of equations: 1 right, 2 wrong, 1 skipped. Hints on 2.
The test app's opinion
"Needs review." Filed under the test app's name.
Seneca's reading low confidence
Not solid yet. Only 4 questions, on one day.
Never tested
GeometryData analysisReading and writing
Listed as "not measured". Never counted as weak.

The tutoring app asks, then decides for itself.
The student connects the tutoring app and says yes to one purpose: planning the first session. The tutoring app gets a short summary. It never sees the questions or the answers, and it never talks to the test app.
What happens next is the tutoring app's choice. Another tutoring app could read the same summary and start somewhere else. Seneca doesn't pick.
Tutoring app
Let's start with systems of equations.
Two problems, no hints. One-variable equations get a single quick check.
Based on results from a test app, 3 days ago.
The tutoring app won't assume
- An SAT score
- Anything about geometry
- How the student compares with others
