EdTech / SAT-Prep Platform · Live
1550+
Live learning platform for a US SAT-prep, college admissions and scholarships company, from the first diagnostic test to the final score.
My role: Contributor at W.A. Management & Consulting (Remote, United States). Built the new diagnostic creation flow and tested features by hand.
Overview
1550+ prepares students for the SAT, college admissions and scholarships. Every student starts with a diagnostic test that finds their weak areas, and the result decides which of three programs they join: Foundations, SAT Intensive or The Last 100.
Behind the public site sits an admin panel where the team writes SAT questions and assembles them into diagnostics, and a learning platform that tracks each student's scores across SAT sittings until they reach their target.
Key Features
- Free SAT diagnostic that maps each student's knowledge gaps
- Placement into one of three programs based on the diagnostic result
- Score tracking across SAT sittings, shown as progress charts
- Admin panel for writing SAT questions and building diagnostics
- Free 30-day trial for new students
What I Built
- Designed a new structure for the diagnostic creation flow, starting from a question bank where admins write SAT questions.
- Built the six-step diagnostic builder: test details, modules, questions, scoring, delivery and review.
- Tested features by hand across the admin panel and student flows, and shipped fixes and enhancements from what testing found.
