I've been reading around here for the past few days and the general opinion tends to be that this years Paper 1 was much easier compared to previous years whilst the Paper 2 was ridiculously difficult. A lot of people seem to be stressed/worried regarding their grade for this course, and i'm no different. With the amount of studying I did I was aiming for a 7. However, after completing Paper 2, I am now concerned regarding my chances of achieving a 6. I was wondering what people think the grade boundaries will be for this session? In my opinion, they should be lower than previous years considering the difficulty of the second paper. After estimating my marks, I expect to …

Okay, so I know the portfolios are 10% each, P1 is 40% and P2 is 40%.. But how is the grade actually decided? To they take the marks from each thing and do an average? Do they take the number you got on the test, (1, 2, 3, 4, 5, 6, 7) and average that? If I got a 5 on my IA, will two sevens be enough to score a 7, or do I need high 7's? What about a 5 on the IA, and a 6 and a 7? In short, how is our final grade decided?

I take my IB math SL exam in less than two weeks, are there any tips or recommendations from previous takers? For those that have taken this exam previously, how much of the exam (paper 1 and paper 2) do you have to get correct in order to get a 4 for the course? Taking into consideration that my IA is aiming me for a 6. Not exact figures, but rough estimations on how much I would have to get correct. What are you thoughts on the exam? easy? hard? Any links or advice would be appreciated!

So it is less 48 hours before the Math SL paper 2 and i am scared ****less because of statistics. Now from what i've learned you can use calculator as the saving tool in the Math exam, especially the statistics part. But now i don't really have anyone here that can helped me to rundown a quickie about it *i'm using a Casio fx 9860G btw*. So if possible, could you guys quickly help me on using calculator for topic like statistics, binomial/normal distribution, tangents and normal of a curve? Thanks a lot in advance for those who spend their time and help

Are we allowed to use the information booklet for both papers in the SL exam? If I sound stupid for asking this, its because I'm in a AP Calc BC class that's mixed with IB Math SL and my teacher is teaching for the AP exam and hasn't really explained the IB test. Also, are we supposed to write in pen or pencil?

Hi, I was solving yr 2007 paper 1 tz2, and found a question that's extremely impossible to solve by hand. It's question no.1 which states The population of a city at the end of 1972 was 250 000. The population increases by 1.3% per year. (b) Find the population at the end of 2002. And I know that the correct formula is 250 000 x 1.013^30, but I thought it'd be okay to write as it is because it is paper 1. But when I checked the markscheme, I was supposed to write the exact value which is 368 318 to get the full mark. So I tried to find any way to solve that manually, but I really don't think I can solve it without calculator. I solved all papers form 2008~2011, but I fou…

So i am writing my IA (Lacsap fraction) and i find out the GS for the En® by a weird method but I am not sure if i can describe it properly. Also i am worried if i use this method i will not get full mark on the use of technology part. So i might use matlab's toolbox which has 3-D surfacing fitting. I am just wondering is this necessary? And how could u achieve a full on this part?

Does anyone know where I can buy a Maths SL study guide? I'm the only student in my school taking SL (we are a very small IB school ) and if my school orders it from the IB website it will take ages to come being it's only one book. I also checked on amazon if there were any but unfortunately there were none. If you know where else I can look for it or just bump in to one by chance could you please let me know? Thank You.

My math IA's were sent in as part of my school's sample and I am actually quite nervous. I stated all of my sources and did my best not to plagiarise. However, I'm still worried that IBO will find something that wasn't intended to be plagiarism and I'll get in trouble for it. I used the posts on this website as guidance to assist me with the task, but I went through and calculated everything myself. I didn't copy and paste someone else's calculations. I cited IB survival in my works cited as well, I hope IB doesn't penalise me for that because if IBO goes on here and finds something in the thread about Lacsap's Fractions or Gold Medal Heights that shouldn't be there (ie. …

My IA is due tomorrow and I'm almost done.

So I soon have my mockexams in Mathematics. My initial plan was to not stress out too much about it since it was "just" mocks (even though it's of course a really nice opportunity to test oneself). However, my predicted grades that I'll apply with to university will be set after my mocks.. so "just mocks" has turned into more than that... So, wondering if you could make some bulletpoints of what stuff I cannot NOT revise for my mock exam in mathematics SL?
