How to use this guide
Read the lesson
Every course slide is transcribed into text you can skim, search and copy. The original screenshot is one click away whenever a diagram matters.
Drill the terms
Each domain ships a flash-card deck built from the official glossary cards, with shuffle and a running count of what you already know.
Test yourself
500 practice questions with the full explanation shown after you answer, so a wrong pick teaches you something instead of just costing points.
Lessons you mark as done are remembered on this device and shown as ticks in the sidebar. The same progress is shared with the classic layout, so you can switch between the two at any time.
