How to Master a Difficult Subject: Science-Backed Ways to Study Effectively, Remember What You Learn, and Use AI as a Tutor

Mastering a hard subject follows a sequence: break it into pieces, learn each piece actively, then revisit it on a schedule.

This book gives you that sequence, built on research into how memory works.

How to Master a Difficult Subject walks you through it in 14 chapters, with methods you can start tonight using a pen and paper.

🧩 How to split a huge subject into pieces you can learn in 25 to 45 minutes

🧠 How to study actively, so every session leaves something behind

✏️ How the blank page and drawing from memory show what you really know

📅 When to review each lesson: after 1 day, 3 days, 1 week, and 1 month

🎯 How an error log points your practice at your weakest spots

🔀 Why mixing problem types builds skill faster than practicing one at a time

🤖 How to use AI as a tutor that keeps your own brain doing the work

Plus a plain-language test for real understanding, sleep, breaks, focus, exam nerves, and a ready-made 75-minute study session.
