Frustration with Olympiad Geo
gulab_jamun   18
N 6 hours ago by cooljoseph
Ok, so right now, I am doing the EGMO book by Evan Chen, but when it comes to problems, there are some that just genuinely frustrate me and I don't know how to deal with them. For example, I've spent 1.5 hrs on the second to last question in chapter 2, and used all the hints, and I still am stuck. It just frustrates me incredibly. Any tips on managing this? (or.... am I js crashing out too much?)

Did anyone get an email from SuMAC checking availability for summer camp you applied for (residential/online)? I don't know whether it is a good sign or just something that everyone got.

why would they only ask the rejected people though? serves them no purpose... only reasonable thing would be to ask everyone or ask only those who got accepted, so that for those accepted cannot make it... their slots would be alloted to someone else
