Well I am preparing for the $\textbf{IMO}$ and I had this really small doubt actually. For geometry I'm basically following $\textbf{EGMO}$ ( I understand going thru it wont make me a pro but its certainly a good starting point isnt it?).
I am currently reading $\textbf{chapter 4 :assorted configurations}$ and its almost done. What i wanted to know was, which chapter should i do next? Computational geometry is cool, but barycentrics seem cooler, and inversion seem even better while projective geo seems godly to me (scrolling thru the chapter i jus saw 3-4 line solutions nothing else like wowww). Soo well what should i do? Also i have done the theory part of complex numbers and most of the questions (no i cudnt do most but yeah i learned) .
If all among bary, inversion and projective are speicialized tools (which cant be used in a lot of problems i mean )than can i start with projective geo ? or is any one of these more versatile in your opinion? Or should i rather start computational geo? I am all ears for your advices n suggestions.
Also good if someone also suggest some good resources for algebra? Like $\textbf{OTIS excerpts}$ is good but it basically only covered inequalities and FEs. for example i came across this question while randomly scrollin thru 2016 SL and its problem A2. It is based as an inequality but isnt really one and id more algebraic-ish (idk how to explain cud u pls have a look?) and A6 and A7. Those arent FEs and inequalities. So where do i get some resources (theory n questions, precisely) for those kinda questions? Also is $\textbf{Pranav Srirams combi book}$ good?
I can do counting questions but obviously olympiad combi is much more different. Is that book a good starting point? I know these are a lot of questions but i really need some guidance right now. Thanks a lot for your help.
