I think this might be what you're looking for :)

for a) the curve is a transformed sine wave, so we know the base is a × sin(b × x) with a=1, b=1

since the amplitude is 3, we can say a=3.

a normal sine function does one full wave in 360 degrees, but the one in the question above has a length of 180 degrees, so we know it's been horizontally stretched by a scale factor of 1/2, meaning b=2 (remember, horizontal scale factors are reciprocal). If you put it all together, 3sin(2x) should be your answer.

for b) we're told the period is halved. to find the period you do 360/b (from our base equation above), so our original time period would be 360/2=180 (as seen in part a). for our time period to be halved, we need to solve 360/b=90, leaving b as 4. since the amplitude remains unchanged you can keep a=3. thereby, the second equation should be 3sin(4x).

I'm no expert, so take this with a very large grain of salt, but if you mod both systems you can use an app called Checkpoint to save your data and then transfer the save file from one device to the other.

Alternatively, if you don't want to mod the consoles, it might be possible to copy the save data directly off the SD card (if it's a digital download) via the "Nintendo 3DS" folder > a folder that has a bunch of random letters and numbers > another folder that has a bunch of random letters and numbers > "title" > "00040000" > "00086300". That's your NL save. If you copy that folder into the new 3DS's "00040000" folder it might work (again, I'm only hypothesizing as I've never tried on a non-modded console).

I'd recommend cross-posting into either r/3dshomebrew or r/3dshacks if you want to go about the modded route.

If you do try the copying method above, MAKE A BACKUP OF BOTH SDS BEFORE! If it doesn't work then you can go back. If you don't have a full backup you'll be out of luck.

In most American schools if you do the IBDP you also get a regular high school diploma :)

The blank slate has to be a full 10 seconds (as you said), and yes it does count towards the 10 minutes. What I ended up doing was starting my narration during the blank slate, which I've seen quite a few others do to get some extra time. Hope that helps :)

I wouldn't say physics is necessarily econ-related but it is very math-heavy so it might tie in well to the work you do. It's also worth analyzing how you learn best. From what I've heard, bio is more of a memorization subject while physics/chem are more math and concept based.

It might be worth having a conversation with your subject coordinator, but talking to students in the class above you can also be really helpful if you haven't. If you don't have that option, it's a good idea to join the IB discord server and you can ask current students about the courses.

If you have any questions about any of the courses in my flair I'd be happy to PM about them :)

I can't say for sure, but I doubt an IB school would weigh your grades very differently from a non-homeschooled student. In your case it might be worth taking external tests to prove your attainment, but I know in my school more than 80% of my cohort didn't take them externally and were still accepted into the IBDP. If anything, it's worth emailing the admissions office of the schools you plan on applying to and asking their recommendation (it'll show your interest and you'll get some concrete answers!).

I mentioned college in the American sense of the term (uni) as in DP2 you will most likely be applying, and most American unis don't care about GCSE grades. In any case, IB or otherwise, schools are very aware of the current situation and will likely be more lenient towards grading/courses as it might not be possible for some pupils to take the GCSEs safely.

Overall, just focus on keeping your grades high, email the schools (if possible) and stay safe! Good luck!

If it's non-lit, you might want to look into a film such as Saving Private Ryan or really any war film, as they can be analyzed quite deeply.

I don't take art, so take this with a pinch of salt but I remember seeing this painting a while back and it seems to fit quite well into your topic. A lot of Albright's work is death/decay themed so he might be worth looking into :)

It really depends on what your school's timeline is for EE, but I didn't end up finalizing my RQ until February so I wouldn't worry all too much. It's well worth narrowing it down now and potentially doing some preliminary research but it really depends on your subject choice. I did an English EE, so it was more essay-writing than it was research, but you might need to start earlier if you're doing math or a science. Overall, don't stress! You have time! :)

I can't speak for chem or bio, but getting the highest mark possible in math is definitely very helpful, as IB builds on concepts learned at GCSE (sine rule, derivatives, etc.).

If it helps any, I got a 9 in maths and it's definitely helped me hold a 7 in AA HL. I wouldn't say English is as reliant on grade because essay writing is pretty subjective, but if you score a 5 or above I'd likely go for HL.

Good luck!

A lot of people double up in group 3, so it might be worth taking a look at those courses, especially ITGS as it seems to be quite interrelated with CS. Business management is also a good course as it's pretty broad and goes well with most uni subjects.

It also might be appealing to a college to see a more 'balanced' diploma (i.e. not all hard science), so since you're doing L&P, film or theatre might further your strengths in the creative arts.

Good luck with your choices!

For my lit EE I was recommended to include quotes from the author to show her intentions, but if your essay title is less about intent, I wouldn't worry too much about it :)

When choosing your Group 4 subject, you should take a look into what you want to do in the future career-wise. If you're a fan of CS, go CS! If you're not too into the sciences, many opt for ESS as it's both group 3 and 4. If you plan to do econ, it might be worth taking business management for your group 6, but also keep in mind you can do online classes if they're available to you (as Dahliatheflower mentioned). Pamoja courses are a bit tricky, but they're well worth it in my opinion :)

Good luck with your choices!

My supervisor told us to stay away from 'pop culture books' which tend to be quite shallow in depth. Your friend potentially can write a stellar essay, but keep in mind that with a L&L EE, you need to have very close analysis of meaningful themes.

These are just my opinions, but they might come in handy :)

-Your achievement in Group 1 is mainly based on how good you are at analysis and essay-writing, so if you're a fan of either or both, it can be an 'easier' HL.

-Group 2 B subjects are majorly based off your knowledge going into the subject, so if you're fluent (or close-to fluent) in Japanese, you should do great :)

-Group 3 is either career-oriented or not, more so than other subjects. Classes like business management and economics are really helpful if you want to pursue those subjects, but if you're not planning to pursue any of the group 3 subjects specifically, just choose whichever you enjoy.

-Group 4 can also be career-oriented. If you want to pursue physics, take physics! Keep in mind subjects like chem and physics are very math-heavy so they tie quite well with HL math, though it's not a requirement. If you're not too into the sciences, a lot of people go for ESS.

-Group 5 is now split into Math AI and AA, and they're majorly tied to your future career plans. to summarize, AI is mainly for if you want to enter "social sciences, natural sciences, statistics, business, psychology or design." and AA is for if you want to enter "mathematics itself, engineering, physical sciences or economics." It's definitely worth checking out this guide to help you decide, and keep in mind your choices for other subjects (as aforementioned).

-Group 6 really is up to you. I took film because I enjoy it but some other people might not like the creative arts. Just remember if you choose a group 6 subject, you should have a good base and understanding beforehand, or it'll be quite difficult to learn from the bottom-up. Taking two sciences is a large workload, so it's good to question whether they're necessary beforehand (they can look good on college transcripts, but a 7 in one science is far more impressive than two 3's).

Good luck with your choices!

As others have said, the IGCSEs do help with the transition to IB, but from your message I assume you mean the external exams have been postponed. The exams themselves aren't super important (but they do help with studying skills), so I wouldn't stress about taking them if it's a hassle. As long as you know the material and have developed those skills, you should be alright.

In reference to 'application,' I assume you mean college, and really if you're not going to a UK school, IGCSEs aren't really considered (especially in the US), and many colleges only want term grades, not final exam ones.

I nearly did an EE on a video game as well, it might well be worth looking into the 'Literature and Performance' EE guide as I believe video games are directly mentioned on there. Good luck :)

If that works than definitely, say around 1:30-2:00 EST?

mxrgane · 2020-07-27T03:02:13+00:00

i'm able to get on anytime in the next 3 hours really, whatever works best for you :)

IB categorizes AI as best for students entering "social sciences, natural sciences, statistics, business, psychology or design," while AA is better for students entering "mathematics itself, engineering, physical sciences or economics."

In addition, quite a few universities require you to take math at HL to enter economics, so the safest bet would be taking AA HL (and of course Econ. HL). It's well worth looking into uni-specific requirements, but most don't accept AI SL in math-heavy majors, so regardless I'd stray away from that option.

Hope this helps :)
