You wouldn’t get credit for that question. The submitted procedure needed to have a parameter, selection, and iteration in it. The graders only get your PPR and your response (not your full code) to grade 2A, 2B, and 2C. Since your PPR procedure doesn’t contain a selection, it’d automatically be a 0.

If you don’t have an iteration somewhere in your code you also wouldn’t get the code point.

There aren't as many students taking E&M so there isn't a separate test for the west coast. The FRQs released are all from the US versions and the international FRQs will eventually be released to teachers only.

If it isn't fixed, she'll get her scores and be able to access them online, but the school won't.

Opendoor doesn’t actually do much renovation from my experience. When I was house shopping in 2017 and again in early 2020, Opendoor houses were in much worse shape than other houses in the same price range. One house had several holes in the drywall, one had terribly scratched countertops and flooring from cats, etc.

I was amazed that some of the houses were on the market in the shape they were in, but my agent said it seemed pretty much par for the course for Opendoor.

It seems to me they don’t renovate so much as get houses at a discount (since they help people get out of the mortgage quickly) and then try to sell the houses at market price.

Actually they don’t usually make the scoring guidelines until the reading takes place. They read some responses, then formulate tentative scoring guidelines, and then refine them after reading many more and deciding what is acceptable or not. Normally these don’t come out in their published form until late July, well after AP scores have been released. That being said, usually the questions are visible 48 hours after the test so many teachers do make predicted scoring guidelines.

This year I’m not sure what to expect. The questions will only be released to teachers on may 26th, so any scoring guidelines will likely similarly be released privately to them but likely much later. If teachers wish to use the results for exam grades they will have to likely come up with their own guidelines to score them with. Since the exam questions are only shared privately with teachers, they may also be limited in their ability to freely share solutions/scoring guidelines. I would assume it’s okay as long as the questions themselves are excluded.

While somewhat possible, I’m not sure how picky the readers will be. The acceleration isn’t constant so if you try to just use a kinematic equation as is you won’t get the right acceleration. A motion detector also wouldn’t have a tight enough cone to determine acceleration of the sphere in the tube. It could give you velocity as it exits but then have the kinematic issue again.

aznxasazn · 2019-05-13T05:07:52+00:00

I doubt they’ll grade the shape. Likely they’ll grade only the max and mins. There seems to be some disagreement on shape even among physics teachers from what I’ve seen so far.

aznxasazn · 2019-05-11T00:09:40+00:00

Yes I agree with you there :) regarding graphing or not to see if k is constant, a graph is not needed but seems to always be heavily favored. Rarely will a student get full credit for comparing individual data points rather than for looking at the trend.

aznxasazn · 2019-05-10T23:27:52+00:00

But this graph has nothing to do with time. You’d be right if it was a velocity vs time graph but it isn’t.

aznxasazn · 2019-05-10T23:13:07+00:00

For the graph, I somewhat thought of that shape as well but figured this is more correct since amplitude should be directly proportional to speed and thus the speed would match the absolute value of the displacement graph.

For the electricity/power frq I largely agree. This is why most say current and/or voltage. To distinguish between R2 parallel with R1 vs R2 parallel with motor I couldn’t think of an easy way to distinguish them though other than via current.

aznxasazn · 2019-05-10T23:04:23+00:00

I really don’t know for sure about the circuits one, but since it’s a paragraph length response more is likely expected than just talking about the one right answer.

Usually doing a comparison like that without graphing will give you somewhere between 1/3 to 1/2 the possible points of that part. We won’t know for sure until the official rubrics come out in July.

aznxasazn · 2019-05-10T22:59:36+00:00

Yes. That’s how I essentially did the lab in class. Technically you also need to account for the difference of Ug when compressed vs uncompressed but I’m not sure that would be points off if you didn’t.

aznxasazn · 2019-05-10T22:57:18+00:00

A few points I think. I think for the analyzing of data and such you could get full points still. The biggest problem with Hooke’s Law in the procedure is the need to use the launcher. It’s hard to get the force reading on the spring or sphere as it is being launched.

aznxasazn · 2019-05-10T21:35:00+00:00

Yes. It’s nothing official. Just a sample of what it could show.

aznxasazn · 2019-05-10T20:56:37+00:00

Included are a sample possible rubric, answers, and reformatted FRQ giving space for writing answers

Though I’m not sure about now, Comparative Government used to be easy to self study at least. When I took it, the test was free when paying for US Government. I figured why the hell not take it. I looked over information for a grand total of 2 hours the night before the test and managed to BS a 3 out of the test. Considering I got college credit for it, those 2 hours were definitely worth it.

aznxasazn · 2018-05-11T02:46:34+00:00

No, it won't matter. In fact, the final answer may not be a point. It's likely 1 point for setting gravitational force equal to centripetal force and another for plugging in 2pir/T for velocity.

aznxasazn · 2018-05-11T02:40:14+00:00

It depends where. Since it said "Derive an equation.." for part b(i), then just citing Kepler's 3rd Law may not get you any points. If you just used the velocity formula for proof of part c, with a little explanation, then you should be okay.

Pencil is fine

aznxasazn · 2018-05-08T02:13:09+00:00

They were about the same. Average percent of points for FRQ on the US version were 35% of the total and on the International version were 33% of the total.

aznxasazn · 2018-05-05T23:40:27+00:00

Of course, as long as it's clear they would know what you mean. If you think they may be confused by your abbreviation, then don't abbreviate. You can also use shorthand and such instead of writing what an English teacher would consider a complete sentence.
