I made a free resource full of helpful hints, tricks, tips, and traps to avoid when preparing for UC Berkeley's Data 140 Midterm 1 - Sept 28, 2026.

‍

Check out the PDF on my Github repository of study guide materials.

‍

This material includes a bunch of strategies for last minute studying for the midterm for day before and same day. It also includes a breakdown of the algebra moves you are expected to know and that will make all of the difference in answering the questions vs getting stuck in a loop on the solutions.

‍

I also have practice midterm questions I have created and accompanying step-by-step solution guides.
