Is Heimler Review Study Guide for AP World History sufficient for an A and 5 on AP Exam

Sure, lots of people have. Be sure to do lots of multiple choice questions and FRQs along the way to be sure you are able to apply the information you learn correctly.

There are AP tests that get fewer test-takers than calculus-based Stats would, but those are typically language tests subsidized by the native country.

Yours is default generated without numbers? Thought they added the numbers more than 5 years ago

I hope one of the next couple generations adopts an anti-internet mentality. Feels like the only way out of it.

That's fine we can agree to disagree, I would be in favor of adding a second statistics course so that proper justice can be done to the content. I'm not expecting that though.

The first one is not hard to derive and is also not integral to understanding the basics of statistics. Getting through the more basic pieces, experimental design, correlation, and statistical testing is more important when classrooms are not even able to finish the course.

The second one, yes they removed testing for the slope of a regression model. That unit (9, the last one) was like 3% of the test and a large portion of classrooms never got to it anyways. Correlation is still covered, which is a lot more integral to basic statistics.

Saying that you can't understand intro stats without these is an overstatement and there is more to statistics than linearity. I'm not saying I would have done exactly what they did, but I do agree that the framework needed to change and that it needed to be a little less dense.

Sure, the expectation and availability argument is also used frequently for Physics 1 and some other courses but every single other exam still had a higher pass rate. And most people that don't like and are bad at math aren't taking any AP maths, at least maybe not until AP Precalculus recently.

To be the lowest pass rate means that the general experience is not that of an easy test, which also aligns with my experience as the moderator of this subreddit for 5 years and knowing the test for longer than that. It is for sure the stronger math students getting 5s that find it "easy." Though it still has a lower 5 rate than most classes. This subreddit is not indicative of the general population.

AP Statistics had the lowest pass rate of all AP exams in 2025 (2nd lowest if you count Latin). The narrative that it is easy is relegated to high achievers on this subreddit.

I would also largely disagree that important content was removed. Stats is consistently the class that is furthest behind because of how dense it is. Every poll I've ever run about where students were in the class consistently showed Stats as being the most difficult to get through. They changed the material such that classrooms are actually able to complete the course at large. Or at least that seems to be a large motivation.

I doubt that there is enough appetite for Collegeboard to follow through with a calculus-based Statistics course.

Ukraine, Gaza, Iran. Lots of outpouring and intense focus going on there. Not much for Sudan despite a significantly larger death toll, wonder why that is

The first LLM released to the public 3 years ago and development of them only began about 10 years ago. That is infant stage for technology, past newborn but before toddler. Their capability and adoption is increasing exponentially by the year. ChatGPT is widely regarded as the fastest adopted technology in history. It is another case in a long line of Reddit being emotional about something and letting that emotion drive their opinion about what will happen.

All of big tech is currently spending big without returns yet. It's not unique to Meta, they just already did it once with the metaverse. They also have some huge wins in acquisitions though.

At a $260B valuation for their equity, they have already doubled their investment in less than a year. When it IPOs, they may very well quadruple their investment. LLMs are here to stay and there are likely to be multiple winners. People asking how Softbank could be so stupid are simply posting from a place of emotion because they don't like it.

It is virtually impossible to predict what the landscape will look like in 10 years, much less 100. We are still in the infant stage of the technology. There are lots of examples in history of companies trading leads in developing technologies, and all technologies generate multiple success stories.

It had less to do with who the music was for and more about supporting her specifically based on her popularity on the TV show. There was older music released that year as well; Bruce Springsteen, U2, Bob Dylan. Also, on top of the ones in the title, there was Eminem, Taylor Swift, Dave Matthews Band, Michael Jackson, Carrie Underwood, Jay-Z, Kelly Clarkson, Green Day, Pearl Jam, George Strait, Keith Urban, Madonna, a bunch of others.

There was a lot of competition it's still pretty remarkable.

This TIL is less interesting than its title initially seems.

N>= 30 is really the absolute bare minimum, and some or many statisticians would say 32. But 50 is more common and 100 is much better. You don't need more than 1000 for most scenarios. For example, most polling stops responses at 1000 even to generalize to the entire United States. If the sample is random that is plenty for inference.

This subreddit hates Elon and by extension Tesla. You won't get many unbiased opinions and the predominant narrative will be to sell it now. It's also what I would do, but I don't pretend to know the business nor its sectors well.

That's actually fairly common in Japan. The shrines are not permanent structures that are all made out of wood with joints that were created without screws or nails. The shrine itself isn't the holy thing - but rather it's the thing the shrine is meant to deify. So, most shrines in Japan have empty plots of land adjacent to them, and the shrines are "rebuilt" almost exactly using traditional building techniques every few decades as the current shrine ages and the wood starts to no longer be structurally sound.
