What are yall's most recent scores on mathCON, AMC 8 and other things? I just wanna know how I'm holding up and if my scores are good! This is the end of my first year in contest math, and I've always been gifted, but can someone tell me if these scores are good? MATHCON: 240
AMC 8: 19 QUESTIONS
AMC 10: 16 QUESTIONS
btw I'm going to 7th grade

EDIT: Y'all I mean 16 questions right on the AMC 10, I'm way too lazy to scroll and find the number of points lol

Let $F_n$ be the $n$ th Fibonacci number. What is the value of $\sum_{i=1}^{\infty} \frac{F_i}{4^i}=\frac{F_1}{4}+\frac{F_2}{16}+\frac{F_3}{64}+...$ ?

Private Forum for Geometry Study

by fossasor, Jun 10, 2025, 10:29 AM

Hi all,

I've recently been trying to improve my skill at competition math, but I consistently struggle with geometry. Since doing math is more fun and motivating with others, I've created the GeoPrepClub. This is a private forum to increase geometry skill and help others increase theirs: we'll have problems, marathons, and much more. This is similar to forums such as "AMC8 Prep Buddies" by PatTheKing, but is focused exclusively on this subject. We welcome all skill levels and hope those with greater mathematical knowledge can assist those lacking in it.

If this sounds interesting to you, sing up below and I'll let you know once I've added you. Although the forum may not have much now, that's because I've only just released it, and I hope once I build a community, It will be a very useful and motivating space for those interested in improving their geometry. The link is
here.

I look forward to seeing you all in the forum!

half of half of half... of cake

by FrancoGiosefAG, Jun 9, 2025, 6:04 PM

Victor and Vicky bought a cake and ate it in the following way: One morning Victor ate half of the cake, in the evening Vicky ate the remaining half of the cake. This process continued in the same way for $4$ days, each eating half of the cake they found. On the morning of the fifth day, Victor ate what was left of the cake. What proportion of the cake did Victor eat in the $5$ days?
