In the fall of 2025 ACE came out with the newly revised course for Physical Science — the 4th Edition. The basic content looks to be the same, but the layout, questions, check-ups, tests, etc are revised and better aligned with the 4th edition format of the other courses.
If you are not sure which course you have, watch the video above for my explanation.

If you want the resources for the 4th edition course, click HERE — but we are gradually building up those resources this year as this is a new roll-out course.
Let me know as you go if you have problem areas and want a video for that. You can leave a comment, or you can use the link above to send a message to me.
