FIU MAC 2312: Calculus II
MAC 2312 is FIU's second calculus course: integration techniques, applications of the integral, sequences and series, and parametric and polar topics. It continues the engineering and science core, and it carries the sequence's heaviest reputation.

What makes it hard
Integration is the first math topic where the method isn't given: you stare at an integral and must choose substitution, parts, partial fractions, or a trig identity, and choosing wrong costs ten minutes you don't have. Then series arrive, the most abstract material of the sequence, and convergence tests demand the same skill of selecting the right tool under exam pressure.
What you'll cover
- • Integration techniques (substitution, parts, partial fractions)
- • Applications of integration
- • Improper integrals
- • Sequences and series
- • Convergence tests
- • Power series and Taylor series
The MAC 2312 study guide
How to study for FIU MAC 2312, step by step.
- 1
Train technique selection, not only techniques
Knowing integration by parts is different from knowing when to use it. Do mixed integral sets where the method isn't labeled. That unlabeled choice is the actual exam skill.
- 2
Keep an integral journal
For every practice integral, note which technique worked and what visual cue suggested it. Patterns emerge after fifty integrals, and pattern recognition is what speed on exams really is.
- 3
Give series double the respect
It's the most failed unit and the least crammable. Start the convergence tests early and build a decision flowchart: which test, triggered by which feature of the series.
- 4
Rework every exam and quiz miss within the week
MAC 2312 compounds: an unrepaired integration weakness resurfaces inside series problems. Same-week repair keeps the debt from rolling forward.

FAQ
Is MAC 2312 harder than MAC 2311 at FIU?
Most students say yes. 2311 has one main skill (differentiation) with rules that always work; 2312 demands choosing among techniques with no formula for the choice, then layers series on top. The course rewards problem volume more than any other in the sequence.
What's the hardest part of MAC 2312?
Series and convergence tests, by reputation and by grade distribution. The material is abstract, arrives late in an exhausting semester, and requires selecting the right test quickly. Starting series practice before the unit officially begins is a genuine edge.
How do I get faster at integration for exams?
Volume with variety: mixed sets where the technique isn't labeled, and a journal of which cue pointed to which method. Speed isn't rushing. It's recognizing the integral's type in seconds because you've seen fifty of its relatives.

MAD 2104: Discrete Mathematics
MAD 2104 is the math department's discrete mathematics course, covering logic, sets, functions, matrices, Boolean algebra, and graph theory, and it's the alternative to COT 3100 in FIU's computing degree plans. It's also taken by IT and other tech-adjacent majors who need the discrete foundation without the full CS theory track.
MAC 1105: College Algebra
MAC 1105 is FIU's college algebra course, covering functions, polynomials, rational expressions, exponentials, and logarithms, and it's one of the university's highest-enrollment gateway courses. FIU runs it through a redesigned lab-based model with software-driven homework and required hours in the Mastery Math Lab.
MAC 2311: Calculus I
MAC 2311 is FIU's first calculus course, covering limits, derivatives, applications of differentiation, and the start of integration, and it's required for engineering, computer science, and the physical sciences. It's a 4-credit, exam-weighted gateway course and a designated checkpoint in FIU's STEM pipeline.
