You should just go with mv^2/r. With v and r obviously being given. Realistically there could even be an electric force on the object that they didn’t mention or whatever So yes you are right the force on B is mv^2/r = 480N The other 2 answers are incorrect but I guess it still counts as a...

Year 11 is in a way a 'free' year. Nothing amounts to anything in terms of marks because you'll start on a clean slate in year 12 anyway. Enjoy year 11, it's honestly the best year of high school but also work hard for it. Try out new ways of studying and figure out what works for you. If you...

How are you finding the new syllabus for maths? Not too bad I hope with the lack of resources 😬

What is your favorite subject?

You've done a whole year of it anyway. Really I don't see a need to do a bridging course. Plus Biology I don't think is that conceptually demanding compared to other subjects so you should be okay imo.

Well that’s what I did and it worked wonders for me.

These were all questions I had during high school when I was in 4u but I didn't know any medalist whom I could ask. Thanks to you now my curiosity is answered haha. The reason I was so curious in high school is because my friend beat me in the AMC and I beat him in 4u so we were kind of...

Out of curiosity how do you think AMC compares to 4U maths and how are the skills in both similar or different, and does success in one necessarily mean success in another? I don’t really know any other medalist I can ask lol so sorry for the bombardment imao

Just curious did you get selected for the IMO?

Yeah of course you can self learn it. If you can pick up a textbook and just learn by yourself then that’s a great thing and I wouldn’t waste time with the bridging course. If you’ve done this before certainly you shouldn’t do the bridging course. If however you can’t really just learn from a...

Yeah honestly what dasfal said. Performing experiments can definitely be really scary at first especially for Chem which probably has the 'hardest' pracs out of the Sciences, but really you'll be fine. There's no point in being so scared about it because it's not actually that hard imo.

What part of practicals are you not that good at? I know for me it was definitely writing up the reports. There definitely ways to get better at the prac part of practicals and the best way is to make sure you truly understand the content because memorizing it may cut it for an exam but not for...

Yeah I second this. My friend did a Diploma in IT at Tafe after dropping out in year 11 and now he's starting his degree in UTS next year.

Let me clarify all my other subjects were all high scaling. So that probably played a large factor in it...

@bokat You can post your videos here now. =)

My school is close to 400 and I sucked and still suck at English...... I Only got an 85 in English standard imao

Yeaaaaaah I've had that and it's normal I think. I mean they're teachers they have a LOT of work to do. This is probably another reason people get tutors because it can help having that 1 on 1 kind of attention. I guess a tutor could help in your situation but do you need one? If your doing...

You'll be fine. As long as now you actually do study and do the homework you will do fine. You may need to get some extra help from your teacher if you don't get a concept because you don't have that knowledge from year 10 but yeah there's nothing stopping you from doing well aside from thinking...

Ooh I get you my bad. I had a look at the Mathematical modelling course and it's not bad. You should be fine doing Mathematical modelling with only 2u knowledge. A lot of the stuff in it seems to be 2u revision and some new stuff that wasn't taught in 4u or 3u either so you should be okay. I...

Hey bokat would you like it if I merge all your threads and then pin it so that way all your solution videos are on one big mega thread. That way it's much easier to access instead of having to scroll back to find them.
