Rutgers CS 111: Introduction to Computer Science
CS 111 (01:198:111) is the first course for Rutgers CS majors and minors, taught in Java. It covers programming fundamentals (variables, loops, arrays, recursion, and basic object-oriented concepts) through autograded programming assignments and high-stakes exams.

What makes it hard
CS 111 has a serious weed-out reputation at Rutgers: exam weight is heavy, the curve is unforgiving, and students with no prior programming experience compete with classmates who took AP CS. Recursion and array manipulation on paper-based exam questions are the classic failure points. Being able to run code isn't the same as tracing it by hand.
What you'll cover
- • Java fundamentals and program structure
- • Conditionals and loops
- • Arrays and 2D arrays
- • Methods and scope
- • Recursion
- • Intro to objects and classes
The CS 111 study guide
How to study for Rutgers CS 111, step by step.
- 1
Write code every single day from week one
CS 111's curve pits you against classmates with AP CS backgrounds, and daily reps are how you close that gap. Thirty minutes a day beats a five-hour Sunday.
- 2
Trace Java on paper, not just in the IDE
Rutgers exams hand you code on paper and ask what it prints. Autograder green checks don't build that skill. Trace arrays and loops by hand, tracking every variable, until it's mechanical.
- 3
Treat recursion as a separate project
Recursion is the classic CS 111 exam killer. Diagram the call stack for small problems, predict outputs before running, and rework every recursion question from recitation.
- 4
Work past department exams under time pressure
Old CS 111 exams circulate through recitations and course sites, and they're the best predictor of what you'll face. Simulate real conditions: paper, timer, no IDE.

FAQ
Is CS 111 at Rutgers hard?
It has one of the strongest weed-out reputations among Rutgers intro courses. The programming assignments are doable; the exams, which demand tracing and writing code on paper under time pressure, are where grades drop.
Can I take CS 111 with no programming experience?
Yes, it's designed to assume none, but you'll need to outwork classmates with AP CS backgrounds. Daily practice from week one matters more than prior experience by the final.
How do I pass the CS 111 exams?
Practice tracing and writing Java by hand, not just in an IDE. Work old exam problems on paper under timed conditions. Autograder green checks don't predict exam performance.
More Rutgers courses
CS 112: Data Structures
CS 112 (01:198:112) is the second core CS course at Rutgers, covering linked lists, stacks, queues, trees, hash tables, and graphs in Java, along with algorithm analysis. It's a prerequisite gate for nearly all upper-level CS courses and a key input for declaring the major.
CS 205: Introduction to Discrete Structures I
CS 205 (01:198:205) is Rutgers' discrete math course for CS majors: logic, proofs, sets, functions, relations, and combinatorics. It's the theory backbone for later courses like algorithms, and it runs alongside the programming sequence.
CS 211: Computer Architecture
CS 211 (01:198:211) covers the fundamentals of modern computer systems: C programming, data representation and computer arithmetic, assembly language, Boolean algebra and digital logic, and the design of the processor, cache, and memory. It's where Rutgers CS students drop from Java down to the machine.
CS 214: Systems Programming
CS 214 (01:198:214) teaches students to build, debug, and test large programs in C on Unix, with heavy emphasis on tools (debuggers, profilers, version control, and IDEs) and on understanding how programs execute and how to measure and optimize performance. It's a core systems course in the Rutgers CS curriculum.
