    • If your grades are good and you have good extracurriculars (and maybe portfolio?), then you have nothing to be worried about. Don't underestimate ESS or Art HL as most people get 5s or below in them. The only downside is that if you were to study sciences or social sciences instead then these courses would not be competitive or even meet pre-requistes in the most competitive schools.
    • IMO Econ is the hardest subject in the entire IB course. Business Management is waaaay easier.
    • Have you looked at youtube videos by MSJChem (Mike Sugiyama Jones), Richard Thornley, or Andrew Weng? They follow the IB syllabus and provide videos for quick review. So the main idea is that ligands can split the transition metal's 5 degenerate (same-energy) valence d orbitals into different energies, depending on the transition metal ion, geometry of the complex and the specific ligand(s). In weak field ligands, the resulting d orbitals are still close in energy (small bandgap), such that they remain essentially degenerate. In strong field ligands, the activation energy to go from lower d orbitals to higher d orbitals are large enough such that electrons fill the lower d orbitals first before the higher ones. In the common octahedral geometry (ML6), the splitting results in 2 d orbitals higher in energy than the other 3. Other complexes have different splitting patterns. The colour of the complex depends on the light that is most absorbed. This energy will partially excite an electron from a lower d orbital to a higher one and partially goes to thermal energy. The equation E = hν relates the photon energy E to the frequency of the peak absorbance light v, or E = hc/λ, with c the speed of light and λ the wavelength. The colour of the complex is then the light that passes through (or get transmitted), which is determined using the colour wheel. So if using E = hv you calculate 700 nm (v = 4.3× 10^17 Hz) or red light, then the complex colour is green because red gets absorbed so green passes through.
    • Scientific writing is not all that similar to what you learn in Lang/Lit or Literature classes. With that said, certainly Lang/Lit is the better option. Consider the option to do Lang/Lit HL and university transfer credits are usually awarded if you score a 5 or 6. If you are concerned with lack of practice, you can practice an analysis piece from a play/poem you are reading once 2-3 weeks (in a 2-hour sitting each time), or by incorporating similar writing into your CAS reflections, which you have to write anyways. You can expand your reading materials to include (modern) poetry so you can understand/analyze them relatively easier than Shakespeare.
    • I already choice my classes for the IB, but now I am starting to regret them. I took the following classes: ESS SL Math SL Eng Lang&Lit HL Business Man HL Arabic B HL Art HL I choice these classes at first, that I will major in marketing. Now, I feel that should have taken Bio SL instead of ESS and Psychology SL instead of art, because I feel these are more relevant subjects. I think that I have taken very easy subjects (apart from math), compared to my friends that take Physics HL, Chem HL and Math HL. I still want to do marketing or even mass communication. please tell me your opinions on my subjects. do you think if I have chosen different subjects it would have made a difference?
