Jose Roberto Cossich G

Joined Aug 2021


Hey, my name's Jose, and I'm currently a senior. I'm about the biggest Indie music fan there is, I love 80s movies (John Hughes goat), and reading in my spare time. I enjoy math because it allows me to express myself artistically, and tutor for the mere sake of those aha moments. I've gotten 5s on AP Spanish Lit and AP English Lang, and I've taken Multivariable Calc and Linear Algebra (which I hope to tutor soon!) I'm currently taking AP Physics C and Real Analysis.

Thank you so much! I'm so excited for the rest of this course, and thank you for starting it! I'm so happy that Schoolhouse has a Linear Algebra series now :) can't wait for future sessions, and have a great day/night!

I want to express my gratitude for this Model United Nations conference. I thoroughly enjoyed the experience of interacting with all the participants. The debates and discussions were thought-provoking, and I gained a lot of knowledge and insights on various global issues. It was an incredible opportunity to engage with intelligent and motivated individuals who share similar interests and passions. Overall, the conference was an excellent platform to develop my diplomacy skills, and I had a lot of fun participating in it.

Bravo! Schoolhouse MUN 2024 was a fantastic event! Each delegate was super respectful of one another, discussions were lively, and the chairs kept things on track. The opening and closing ceremonies were excellent and very fun too! I am looking forward to next year's Schoolhouse MUN. Thank you all for all of your hard work!

Thank you so much! This was a great session. I appreciate how you showed me a proof of the formula I didn't understand - proving things and knowing why a formula works has always worked best for me when learning. This was a great session, and I can't wait for the next one!
