This semester, I am a TA for CS 70 with Professors Babak Ayazifar and Anant Sahai.
My discussion sections are Wednesdays and Fridays 23PM in Dwinelle 105, and my office hours
are on Fridays 45PM in Soda Alcove 347.
Discussion Notes
For every discussion, I've created recap sheets which serve as short summaries of the most important topics being
discussed, as well as
some tips that I've gathered which are useful to know. Students in the past have told me they would find such a
resource useful, so this is
my attempt at fulfilling that need. My philosophy is to think of them as takeaways or the main ideas behind the
notes/discussions; they can't replace the act of working through the notes or discussion problems, but they're
useful to read before and/or
after to understand the big concepts.
For more sheets of a similar flavor, check out Alvin Wan's crib sheets. I try to update these by EOD of each
discussion.

Resources
Here are some handouts I've written on various CS 70 topics.

Discussion 0A Slides: My slides discussing an overview of CS 70 and detailing some useful resources.

Lagrange Interpolation: A step by step derivation of Lagrange Interpolation.

Balls and Boxes: A short, detailed note on the ways to use the Balls and Boxes counting method as well as its different applications.

Hard Counting Problems: See title. Some extra counting practice. Counting is a misnomer, more of general combinatorics.

Calculus and Continuous Probability Review: A quick refresher of single and multivariable calculus in the context of continuous probability that I wrote last semester.

Central Limit Theorem: Intuitive explanation of CLT and why it has to be true.
Evaluations
You can view my evaluations from this semester here. My students were (mostly) very kind in their reviews, and I'm very grateful for that. Hopefully this gives an idea of what I was like as a TA!Feedback
Let me know how I'm doing! Feel free to give anonymous feedback here.
