All the ACT theory you need, organized by syllabus topic and integrated with practice on the app.
Everything you need to know before diving into the theory.
The ACT is a high-stakes admission test: candidates who score in the top percentile secure a seat in the limited-number program they applied for. Your preparation has to match that pressure — broad enough to cover the full syllabus, but selective enough to spend time on the topics that actually move your score.
TestBuddy's digital manual is built around the official ACT syllabus and reorganised into bite-sized lessons. Every section is paired with practice questions on the same micro-topic, so theory and drilling stay tightly coupled instead of living in two separate worlds.
Theory keeps getting refined every time the ACT test format changes — we update one source and your manual updates everywhere. No more obsolete paper editions sitting on your desk.
Built to be read, searched and revisited — not just printed.
Every ACT topic and sub-topic explained at the depth required by the official program.
Memorable shortcuts and mnemonics for the high-frequency questions in the ACT.
Step-by-step solutions show how to approach each question type under exam conditions.
Every chapter has a direct jump to relevant ACT drill questions in the simulator.
Find any concept in seconds, save the ones you struggle with, come back the next morning.
When the ACT program changes we update the manual — your study material never goes stale.
Each section is fully covered in the digital manual — review theory, then test yourself with linked practice.
