Has anyone mentioned Caltech yet?

I agree with an extra year, or as much time as he needs to arrive at college completely prepared.

There's a fair bit of grade inflation, honors inflation, academic inflation in the US anyway. Lots of students are showing up for colleges with high GPAs and honors classes. If you feel your class is more rigorous than a regular class, then call is honors.

Have your son take screen shots of the threatening texts and save them to the cloud. Consider telling the roommate that you have done so. Consider sharing these threats with the RA. Is the RA also an undergraduate? Consider agreeing to mediation only if an on campus housing official or dean is present. All these suggestions may escalate the situation, so think carefully about these options.

There's a kid in my neighborhood who volunteered with a legal clinic serving the poor when he was in high school. Seems like a great experience to learn more about the field. (Otherwise, I know very little about law school.)

We just read it aloud, and well, some of them I plain just didn't understand. I felt like I needed more examples to fully get it. But I really don't have the background in this area.

To add, you might relabel the axes to more accurately relate what they are measuring. For example, you might be describing volume as a function of temperature. Then the y-axis would be labeled V and the x-axis labeled T. Another example might be population versus time. The y-axis might be labeled P or N (for number of people?) and the x-axis would be labeled t. So it's not unheard of to use different labels for the axes, and it's worthwhile to explore this in depth. V = mT + b?

Don't be discouraged. The problem you cite is a tough one if you don't have a thoroughly deep understanding of graphing and lines. Relabeling the axes from x and y to T and Q, while not unheard of, does remind me of this recent Math With Bad Drawings: Baby Name Book of Variables, especially the function x(f) = f - f^3, lol. As your student collects more and more tools in her problem solving toolbox, it can be tough to remember them all. I like using old AMCs (maybe start with the AMC 8) to throw different problems at my kids so they are reminded of some long-forgotten techniques and theorems. Keep mixing it up. The real world won't be telling her which theorem to use; they just want the right answer.

Does the ES really think that math ends at geometry? That your student won't study any math in high school? I think you know now how much weight to give to this person's future opinions.

Python.

Just start calling: private schools, public schools (we've always had better luck with public for some reason), after schooling and tutoring centers. Just start with the schools closest to you and work your way out. Tell them you don't need accommodations (if you don't) and you are willing to pay any fees. Tell them you will use your own homeschooling code so your student's score won't affect their average. Be super nice since they don't have to let you join their class.

Actually, I think the odds are much higher. For example, assume that each elite college has an 8% acceptance rate. The probability of getting admitted to at least one of those elite colleges is, by complementary probability, 1 - the probability that her son does not get in to any of the colleges. Assuming he applies to 10 elite schools, his probability of getting admitted to at least one school is 1 - (0.92^10) = 0.57 which is still not guaranteed, but a heck of a lot better than 8%. If the acceptance rate of those 10 schools is down to 5%, then his probability of being admitted to at least one is 40% (1 - 0.95^10). If he only applies to 5 schools, each with an acceptance rate of 5%, then his probability of being admitted is only 23%. But that assumes that each school's probability of acceptance is independent of the rest, which I argue may not be true. In fact, it's probably more likely that if he were admitted to MIT, then he is likely to also be admitted to at least some of the other elite schools. Likewise, if I apply to Duke and I don't get in, I'm not going to hold my breath on getting in to Harvard.

To not appear tacky, tell them that your dc really wants to attend their school, but you can't as a family ignore the significant cost savings by attending his second choice school. Is there anything they can do make your decision easier? <Discretely slide a copy of his award letter from second choice school across their desk.>

I'm going to venture that since you don't have a state residency advantage here, your ds will have an easier time getting admitted to a name school than to a state school that is typically viewed as a safety. I think what you need to figure out is where do IMO champions end up? My sense is that the MITs and CalTechs and similar schools will see "IMO medaler" and say "He's in. No question." And bonus points for being from NZ since that adds to the uniqueness and diversity of his class. The state schools will say "He's not from Ohio, he's not from North Carolina. He's out." Or they might say, "He's from overseas so he's paying full freight, and we need the money for a new stadium. What's IMO?"

Do the a-g's need to be satisfied by the end of junior year in order to count?

It may be a first world problem, but you are paying first world prices. I've seen seating charts where it's clearly indicated that some seats have an obstructed view. They can do the same.

I notice that none of the pinned threads address options for high school English. I can really use your recommendations for any online writing or literature courses. Thanks!

Stanford Online High School options to go full time and graduate, part time or single class expensive need to complete extensive application like all full time high schools, course quality varies: much of it is excellent, but not across the board administration attempts to create a real school-like community of students and parents, including in person meet ups, competition teams, dances and graduation ceremonies

Jeepers, you'd think they'd double check everything before scaring you?

The most recent issue of Muse Magazine is all about climate change. You may be able to find a copy at the library.

Okay, I'll provide a dissenting opinion. If you are hoping to score a 5, AP chem is a lot of work. AP chem was my daughter's only AP last year (her freshman year). But AP chem was her number one priority and the course she devoted much of her academic attention to. OTOH, she had not had high school chemistry prior, so she was essentially learning everything for the very first time. I'm not familiar with APUSH, but if you need to pair it with another AP, I'd pick something easy or something your student is already familiar with. (Has your student already studied high school US history?) If your student has already had high school chemistry, she will probably not need to study as much as my dd. Also, if you are going to be happy with a lower score, then you probably can afford to divide your time among other challenging classes. YMMV!

Going through the course audit process gives you access to their sample syllabi and suggested textbooks, which can make it easier to plan a course of self-study. You don't even need to the complete the audit, but OTOH, it's hardly any work at all.

My kids took the AMC/MathCounts online AoPS classes for fun. But I would say that if you are already studying out of AoPS textbooks, there is nothing new or different there.

Both my daughters took their first AP exams in 8th grade: AP computer science A which has a reputation for being one of the easier APs. (My dds also had a fair amount of programming experience before taking the class.) If they get a good score, you'll need to notify the college board that you want to have the scores retained on their record or they might erase it, for some reason I don't understand.

My favorite part of the MCT series is Caesar's English. The rest is okay, but don't miss CE.
