1. ## Relative uncertainties

Okay guys my teacher just told me she contacted an IB Chem examiner she time ago and solved the issue... He just to me about this and it happened like two weeks ago Thanks again
2. ## Relative uncertainties

Ok so far I got every combination of answers possible.... Teacher and first reply says round first. Sasanne says round second. You say don't round. Hmm...
3. ## Relative uncertainties

Actually my teacher told me to do the first Isn't it amazing that everyone is giving different answers and its like everyone is acting so confident about what they are talking about? This is confusing....
4. ## Relative uncertainties

Thanks. Can anyone confirm this?
5. ## Relative uncertainties

Hey! I have a doubt about relative uncertainties in the internal assessment... If you have to divide two values with one another. Say A/B. A has an uncertainty of 13.7% and B has an uncertainty of 4.1377%. I heard that the uncertainty must be rounded to one significant figures. So does that mean rounding them before giving 10%+4%=14% or 13.7%+4.1377%=17.8377% then rounded to 1 sig fig giving 20%? I would really appreciate any help. Thanks
6. ## A CMS software can be used for the ITGS proyect?

I never heard of any software that are "ok" or "not ok", it doesn't matter to be honest... as long as you do a large part of the work and not let the software automatically generate the whole project!
7. ## ITGS...Lets Help each other out

Don't worry... with hard work you could score as high as a 6... I even dare to say 7 if you work ridiculously hard and like make ITGS a mundane part of your life that will remain with you even after you finish the IB Diploma.... :-) Are you taking it in Higher Level or Standard Level?
