  1. Hello everyone, I am currently doing 4 HL's but I need to drop one as soon as possible. Right now I am taking Math, Physics, Chem and Econ HL. I want to be an astrophysicist. I know that I need to keep Physics HL, I do not know about Math because even though I am strong at math, the teachers say that it will be very challenging for me and I will not be able to get the score I want, but if I drop to Math SL she said that the course would be kinda too easy for me not letting me develop my skills. I have to choose between Chem and Econ which one to drop. If I were to have Physics, math, and chem HL the teachers say I would pick the "death combo", and I can see why. But they complement the best If I were to pick Physics, econ, and chem HL, would I need more maths but should I be okay with just Math SL for astrophysics? or should it be better if I keep Math HL? The other option would be to have Physics, math, and econ HL, in which math would be the most challenging one for me. I have tried the 4 for a semester, and I am allowed to keep it like that for another semester before yr12 starts, but me and my math teacher would like if I decide as soon as possible, if possible before the second semester of my first year starts. Thank you all for your help! All thoughts are welcomed!
  2. Hi guys/girls, So I am writing because I chose: - Maths HL - Physics HL - Economics HL - Chemistry HL - Spanish B SL - English Lang. & Lit. SL Although I believe I could work through this as I have quite good grades (not trying to be cocky), I think this will be too tiring for me... I was thinking of changing Chemistry for something much easier. I would like your opinion as well as a short summary on the following courses please: Geography SL, Business SL (I don't want to take Econ and Business but it's still an option), Computer Science SL (I have a very basic knowledge of programming). If it interests you, I am not sure what I want to do with my life or in uni but it's probably going to be something to do with engineering, economics or business. My future dreams are to own my own company and be able to run my own business, not to work for major companies on a 9 to 5. Don't know if this helps with your suggestions but thought it was worth mentioning. Thank you so much for your time, Antonio
  3. Hello, i take physics SL, English A1 SL, Maths SL, Chemistry HL, Business HL, Arabic B HL, i was wondering if you could tell me the possible courses i can take in university with these subjects, i was sort of thinking of taking business as a course in university, but it seems very light considering what the good grades that i get, and i could take it anyways later. Thank you in advance
  4. Hi guys, I'm having trouble coming up with ideas for my lab. I'm really not all that creative, so I've been stressing about this. My teacher had given me an idea, but when I tried it, it completely failed, and now I'm extremely discouraged. I really don't know what to do. The lab has to be related to ionic compounds or covalent compounds. It obviously can't be too simple as well. I had originally wanted to measure the colour of a compound after changing it's concentration, but that was too simple. My teacher gave me the idea to use chlorides from group 2 in the periodic table, measure their pH and then their conductivity, but the reason it didn't work was that the pHs were too close together (and the probe was being moody). I understand if you're not allowed to give me complete ideas, but anything will help at this point. Maybe something you write will spark an idea. Excuse me if I'm not using proper chemistry terminology, I don't do the program in English. Thank you for any guidance you can provide.
  5. Hi there! I need some urgent help with my IA. Which I was never good at and am pretty lost right now. So basically, I was doing my IA and I was a bit confused with finding the equivalence point based on the data I have collected ( Note that this is a DCP and CE IA, the design is set by the teacher) I found the half equivalence point, since pH= pKa, i thought I was on the right track.. .. but there is one problem. My pKa does not register with any acid in the data booklet The correct answer would have been ethanoic acid (with a pKa of 4.76) I tried doing back backsolve with 4.76 but that was simply impossible. Because of that I do not know how to continue with my experiment. Since I am unable to identify the acid, this renders my DCP invalid and I cannot write my CE. *** Long story but I'm unable to get any help from teachers so I hope y'all can help me out a bit here!
