u dont need to do saponification, polymers try the 2019 additional questions if u haven't already they make u write a 7ish marker and their sample ans is half decent

np :) lmk if u need anything else, happy to help 🙏

idk prolly given 2021 was the hardest paper, but the 2019 additional questions has some pretty hard ones

notes from my summary attatched, idk if they'll be of any use but this is normally my approach

Usually reference to the gibbs free formula resulting and the resulting gibbs free value (spontaneous/not) - which is basically same as the table (the one w entropy vs entropy and the boxes state spontaneity) ie combustion of octane (GIVE EQUATION) - enthalpy of combustion is always negative...

syllabus mentions "nylon and polyesters" by name as an example in the same way they do for addition polymers, it specifies MODEL and compare structure, properties and uses of condensation polymers so bare minimum id say remember what types of monomers can be used + the linking functional group...

pretty sure you do, it's not that hard tho the 6 tells u the number of carbons then u js gotta remember it's joined by an amide group

look there's no point in worrying about it now, idk how median has already been predicted given we sat the paper 2 days ago so it is entirely likely it is just rumor, we don't know the marking criteria and we don't know the scaling. It's completely out of your control and whatever happens...

we need to know theory

lowkey id rather it than polymers

nahh my memories good for everything except solubility rules its so annoying, honestly I doubt they'd put a rlly long ion ID thing but they hypothetically could I suppose, we had to draw a flow chart for trials + explain why it identifies 3 ions which was about 5 marks. I feel like they wouldn't...

yeah true, I'm hoping there's time for me to plan out some of my responses for some of the chunkier theory questions bc I'm actually so uncohesive if I don't think about the way I'm phrasing things lmaoo but who knows ig

controversial but i wouldn't say bio was easy easy this yr, I think it was one of those tests where they're gonna mark for specifics that people might of missed for questions that seem relatively easy on the surface but want reference to specific things (like the CFTR question), especially since...

u need to know main principles of precipitation titration (normally using silver, using an indicator with a higher solubility than the precipitate formed, etc) but since the syllabus doesn't specify, you don't technically need to know specific methods for precipitation titrations better safe...

literally praying its actually like this
