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 again, this session was explained really clearly which made it easy to understand

thank you again for another great session, i learned a lot about l'hopital's rule and applications, and i also appreciate you re-explaining certain steps for me. also, thank you for going through proofs because it helps the understanding of actual calculus so much more and is generally just really interesting. this series in general has honestly been pivotal in restoring my love of learning, so a million thanks to you jose.

thank you again, the other proofs of L'hopital's rule were very interesting and I appreciate you going through the effort of re-explaining to make sure everyone understands it, considering this is the gateway to more rigor in calc.

Thank you, Jose! I apologize for coming in late to the session - but you were very patient and explained everything well! Even though I didn't get most of the practice problems right, I was actually getting the hang of it by the end of the session. Thanks again, and I hope to see you in another session!
