Your code is only half of what a grader sees. The other half is documentation: the comments inside your files, the README that explains how to run the program, and the notes you attach when you submit. Graders read all three. Most coding rubrics assign points to them directly. A student who writes clean code […]

Summer is the longest uninterrupted block of learning time a student gets in a year. Eight to twelve weeks with no exams, no group projects, no semester deadlines. The decision of what to learn during those weeks compounds for the next decade of a programming career. The hard part is choosing. Twitter says learn Rust.

The notebook runs clean. Every cell green. Output looks right. You download the .py file, upload to Gradescope, and the autograder fails 9 out of 10 tests. The code did not change. The environment did. Jupyter and standalone Python are not the same execution environment, and the differences hide in places no Python tutorial covers.

There is a skill that separates students who get unstuck quickly from students who spend entire weekends staring at the same bug. It has nothing to do with how good a programmer they are. It is about how they ask for help. A good question gets a useful answer in minutes. A bad question gets

Reading a CSV file in R takes one line of code: read.csv(“yourfile.csv”). The function loads your data into a data frame, which is the table-like structure R uses for almost every analysis. The harder part is what happens before and after that single line: putting the file in a place R looks at by default,

A summer programming course covers the same material as a fall or spring one, but in roughly half the time. At UC Berkeley, the same CS61A course that runs over 15 weeks in the fall runs over 6 weeks in the summer. The lectures, the homework, the exams, and the project all stay the same.

The “could not find function” error is one of the most common errors R students hit in their first weeks of using the language. The error message looks intimidating, but the cause is almost always simple. R is telling you that the function you typed is not currently loaded, not currently spelled correctly, or not
