Georgia Tech MATH 3012: Applied Combinatorics
MATH 3012 covers counting techniques, recurrence relations, generating functions, graph theory, and related discrete mathematics. At Georgia Tech it's a requirement for several CS threads and a staple of the CS-degree path, sitting alongside the theory coursework it feeds.

Build my MATH 3012 study planWhat makes it hard
Combinatorics problems resist pattern-matching — two counting problems that read almost identically can need entirely different approaches, and exams exploit exactly that. Students coast on the readable lectures, then discover on the first midterm that recognizing a technique and selecting the right one are different skills.
What you'll cover
- • Counting principles and binomial coefficients
- • Inclusion-exclusion
- • Recurrence relations
- • Generating functions
- • Graph theory and trees
- • Network flows and matching
The MATH 3012 study guide
How to study for Georgia Tech MATH 3012, step by step.
- 1
Work problems in volume, not depth
Combinatorics fluency comes from exposure to many problem variants — two near-identical counting problems can need different techniques, and only volume teaches the distinction. Set a weekly problem quota and hold it.
- 2
Justify the technique choice in writing
For every problem, state why this counting approach and not its neighbor — permutation versus combination, inclusion-exclusion versus complement. The selection reasoning is exactly what exams probe.
- 3
Translate word problems slowly and deliberately
Most lost points trace to misreading what's being counted — ordered or not, repetition allowed or not. Make the translation step explicit before any formula appears.
- 4
Keep graph theory definitions exam-precise
The graph units reward exact definitions — trees, matchings, planarity conditions. Flashcard the definitions and theorem statements, since partial recall earns nothing on proof-adjacent questions.

How Fennie helps with MATH 3012
Fennie's Daily Plans enforce the steady problem volume that MATH 3012 actually rewards, paced to your exams. Chat through technique selection — why inclusion-exclusion here and a direct count there — and drill generated quizzes on counting variants until near-identical problems stop fooling you.
FAQ
Is MATH 3012 hard at Georgia Tech?
It's deceptively hard — lectures are readable and homework feels doable, but exams exploit how easily counting problems disguise themselves. Students who practice technique selection on volume do well; students who memorize formulas get sorted.
Do CS majors need MATH 3012?
It's required for several CS threads and a standard part of most Tech CS degree paths — check your thread requirements. The material also feeds directly into algorithms coursework and the probability courses that follow.
How do I study for MATH 3012 exams?
Volume over depth: work many counting problems and write down why each technique applies. Exams punish formula-matching, so the justification habit — ordered or unordered, repetition or not — is the highest-value practice available.

MATH 1551 — Differential Calculus
MATH 1551 is Georgia Tech's differential calculus course — limits, derivatives, and applications — compressed into a 2-credit format that reflects Tech's assumption of strong incoming math preparation. It's the entry point of the MATH 155x sequence for students without AP credit.
MATH 1552 — Integral Calculus
MATH 1552 covers integration techniques, applications of integrals, improper integrals, and infinite series including Taylor series. It's required across virtually every Tech major and is most students' first full-weight Tech math course, since many place out of 1551.
MATH 1554 — Linear Algebra
MATH 1554 is Georgia Tech's linear algebra course — systems of equations, matrix algebra, vector spaces, eigenvalues, orthogonality, and least squares, with applications like Markov chains and PageRank. Required across engineering and computing majors, it's one of the highest-enrollment courses at Tech.
MATH 2551 — Multivariable Calculus
MATH 2551 is Georgia Tech's multivariable calculus course — vectors, partial derivatives, multiple integrals, and vector calculus through Green's, Stokes', and the divergence theorems. It's required across engineering and most science majors and runs on the same common timed exam system as the rest of the 1000-2000 level math core.
