How to Study Math From Scratch

Adult learners returning to math — the order of operations, where to start, and how to avoid relearning the same gaps.

What you'll learn

  • Where to start (pre-algebra)
  • Diagnostic-first approach
  • Order of topics
  • Avoiding 'I've forgotten everything' panic

The mistake most students make

Jumping into calculus to 'relearn math.' Without algebra fluency, calculus feels impossible. Start where you actually are.

How Fennie helps

Fennie's diagnostic identifies which level to start at — pre-algebra, algebra, geometry, precalc — and builds forward from there.

Step by step

  1. 01Take a diagnostic quiz to find your actual level
  2. 02Start at the lowest topic where you scored below 80%
  3. 03Daily 30-minute sessions, mixed practice
  4. 04Move forward only when retention is solid
  5. 05Use Fennie to identify gaps quickly without rereading textbooks
