I just published my video explanations to the math questions in the four practice tests that are part of The Official ACT Prep Guide 2025-2026 that was released in May 2025.

All of the four tests are modifications of previously released official ACT tests. The list below shows the source of these four practice tests.

• Test 1 (25MC1): Modification of 24MC1(Test 1) from The Official ACT Prep Guide 2024-25.
• Test 2 (25MC2): Modification of 2021 December ACT test(E23).
• Test 3 (25MC3): Modification of 2019 December ACT test(C03).
• Test 4 (25MC4): Modification of 2020 July ACT test(C01).

The Official ACT Prep Guide 2025-2026 will be released in May 2025 and will reflect ACT test enhancements effective September 2025 ACT test(paper and online) and April 2025 ACT(online only).

Here is a quick summary of what is new about The Official ACT Prep Guide 2024-25 that was released in summer of 2024.
