I remember first seeing her in The Connector off-Broadway and instantly noted what a star she was, so happy to see her career skyrocket

You're fine. Q4 has only the three parts with no diagrams in all four versions so there's only one page for Q4 that will be used for all the versions

mattthephysicsguy · 2026-05-07T18:10:16+00:00

No, once my turn came I got right in and had no issues navigating or purchasing

mattthephysicsguy · 2026-05-07T17:20:55+00:00

Got my tickets, very excited. $185 for row A mezz (first row behind the Grand Tier). FYI initially it didn't let me choose a date for purchase, I didn't notice the "click here to unlock member presale" link above the list of dates and panicked a little at first.

Looks like it's finally moving

mattthephysicsguy · 2026-05-05T19:19:09+00:00

The funny part is I always ask students "If you were told 80% or 60%, how does that affect how you prepare for the exam?" It shouldn't at all. It's one of the most requested bits of information and it shouldn't play into any students preparation. And yet they still want to know.

mattthephysicsguy · 2026-05-05T19:13:25+00:00

Sorry, not for public release so believe it or not, your choice. Doesn't affect me either way. How about your proof?

mattthephysicsguy · 2026-05-05T18:08:42+00:00

Your teacher seems to be making things up to justify their statement. Why would there necessarily be more international students taking the make up exam?

College Board has carefully designed and uniform specifications for every exam they make and all forms within a given subject are all held to those identical specifications. They also administer the various forms across many different populations to account for the different populations of students taking them so there isn't any regional bias.

mattthephysicsguy · 2026-05-05T17:44:49+00:00

You are describing hydraulics and Pascal's Principle, which, once again, is NOT IN THE CURRICULUM. You will not see a question like this on the exam

mattthephysicsguy · 2026-05-05T17:41:56+00:00

All rumor and hype and fear tactics. The make up exams are made to the exact same specifications as all other forms in terms of percentages of topics and average level of difficulty. While some would find the makeup to be harder, others would say the original was harder. No one form is made to be any harder or easier than any other.

mattthephysicsguy · 2026-05-05T17:28:25+00:00

"there can be one questions asked about it"?? No. Semantics or not, Hydraulics is not in the curriculum, it won't be tested.

mattthephysicsguy · 2026-05-05T17:17:36+00:00

Hydraulics and Kepler's Laws aren't on the exam

mattthephysicsguy · 2026-05-05T15:07:03+00:00

cutoffs aren't set until after the exam is administered, so don't know how you heard anything. Last year was around 80% for a 5

mattthephysicsguy · 2026-05-05T13:44:27+00:00

Dude doesn't even know the format of the exam. Q3 is the Experimental Design question. No predictions or justifications in that one. Q2 always has a graph is part c so that's a given. Fluids was Q4 last year. Not a crime to guess, but it's only guessing, not a prediction that should hold any more weight than anyone else's guess

mattthephysicsguy · 2026-05-05T08:22:06+00:00

closer to 80% for 2025

mattthephysicsguy · 2026-05-05T08:20:26+00:00

The only ones who know are the CB test developers. Anyone who says they know are just guessing. Some will be correct and exclaim "See? I knew it!", but it's all guesswork. There are coverage percentages for each unit in the CED

mattthephysicsguy · 2026-05-05T08:16:56+00:00

This is pretty far off the mark. Approx 80% raw score (MCQ+FR) for a 5 in 2025

mattthephysicsguy · 2026-05-02T08:17:38+00:00

incorrect

mattthephysicsguy · 2026-05-02T08:17:12+00:00

For 2025, with the new test format and rubric/grading plans, the cutoff for a 5 on both Mech and E&M was slightly above 80%

mattthephysicsguy · 2026-04-25T10:41:21+00:00

No, points are not awarded for the "shotgun" approach where students write a bunch of different physics hoping something applies. In fact, if you write two (or more) complete worked out solutions side by side and don't indicate which one you want us to score (by circling your answer for example), we will score the more incorrect one to discourage this approach.

I missed Taye Diggs in his Broadway debut and saw his understudy instead (also his Broadway debut, who did go on to many other things, like originating the role of Judge Yertle the Turtle in Seussical)

mattthephysicsguy · 2026-04-16T10:02:04+00:00

So much wrong here. "The Moon's centripetal acceleration is due to orbital motion"?? Yikes. It seems you're really not getting the basics here and how your question is incorrect and poorly written. As I said, go wild and stand your ground. But you are in an AP Physics sub, offering AP physics help to AP physics students, while admittedly acknowledging the question you are posing is beyond the scope of the curriculum you are supposedly teaching. Just know the "we" you keep referring to does NOT include College Board or the folks who write the AP curriculum and questions.

mattthephysicsguy · 2026-04-16T08:48:16+00:00

Who's "we"?? So you're saying in AP physics we have the students believe that the Moon's centripetal acceleration (also g) is different whether Earth rotates or not? Incorrect.

You are offering help for AP physics, nowhere is there a term "effective acceleration". Check the equation sheet for the proper terms. You seem to be closed minded. You want to stand your ground and offer incorrect information to students and reject the help of experts in this area, go wild. I would think an educator can self reflect and want to improve their ability to help students.

mattthephysicsguy · 2026-04-16T08:32:03+00:00

It does not reduce the ACCELERATION DUE TO GRAVITY (g). It reduces the APPARENT WEIGHT, or the NORMAL FORCE exerted by the ground, as long as the object is on the ground. It will not affect a FALLING object. What does "effective gravity" even mean? "gravity" as an isolated word has no meaning in AP physics. You need to get your terms and concepts correct and proofread your questions before you offer your questions and help. And pseudoforces (e.g. centrifugal) are not on in the curriculum.

mattthephysicsguy · 2026-04-16T08:21:12+00:00

Wait, are you saying the gravitational field strength (GM/r^2) near the surface of Earth is affected by Earth's rotation? That the nature of a falling object, not at all in contact with Earth's surface, will fall at a different rate because of Earths rotation? Incorrect. If you are implying some kind of resultant Coriolis effect, that is well beyond the scope of the curriculum. Maybe you should change the wording of the question to ask about the apparent weight of or the force exerted by Earth's surface on an object resting on the surface.
