Most students lose points here. Ampongan uses a mnemonic system exclusive to this reviewer to memorize the common limitations on the taxing powers of LGUs.

We spoke to recent board passers to understand the real-world impact of the Ampongan Tax Reviewer Exclusive.

"I took Tax three times. The first two times, I used common textbooks. The third time, a friend gave me their old Ampongan Exclusive. The way he explains remedies—the flowchart of when to file a protest vs. a claim for refund—finally clicked. I got 85% on Tax on my third take." — Maria R., CPA (2023)

"The pre-board questions destroyed my confidence. I was scoring 50%. But when I saw the actual Board Exam questions, they felt EASY. That is the magic of Ampongan. He over-trains you." — Joshua T., CPA (2024), Top 18
