SNHU CS-300: Data Structures and Algorithms: Analysis and Design
CS-300 is SNHU's data structures course in C++: vectors, linked lists, hash tables, and binary search trees, plus Big-O runtime analysis. It builds to the ABCU advising program project, where you choose a data structure, justify it with runtime analysis, and implement a course-catalog loader and printer.
Fennie is independent and not affiliated with Southern New Hampshire University. This is an unofficial study guide.
Build my CS-300 study planWhat makes it hard
This is widely called the hardest course in the early CS core. The pseudocode and runtime-analysis assignments demand a different kind of thinking than earlier project courses, and the final project requires both working C++ and a written defense of your data-structure choice — students who can code but can't explain Big-O lose points on the analysis half.
What you'll cover
- • Big-O notation and runtime analysis
- • Vectors and linked lists
- • Hash tables
- • Binary search trees
- • Sorting and searching algorithms
- • Pseudocode and design documents
The CS-300 study guide
How to study for SNHU CS-300, step by step.
- 1
Learn Big-O with each structure, not after
For every structure you implement, state its insert and search runtimes the same week and say why. CS-300 grades the analysis as heavily as the code, and bolting it on later doesn't work.
- 2
Write pseudocode before code — it's graded
The design assignments are direct rubric items, not busywork. Practice sketching logic in pseudocode first until it feels natural, because the final project requires it in writing.
- 3
Build a runtime table early
One page: vector, linked list, hash table, BST down the side; insert, search, delete across the top. Fill it in as you go and the final project's written defense writes itself.
- 4
Clear the calendar for the BST and hash-table weeks
Students consistently report these as the heaviest modules in the course. Bank time in the lighter early weeks so you can slow down when the trees arrive.
- 5
Start the ABCU analysis before the code is done
The written justification of your data-structure choice is half the project grade. Draft it while you implement — the reasoning is fresher and the Sunday crunch is smaller.

Run CS-300 through Fennie
Upload the syllabus and Fennie builds a Daily Plan that front-loads the heavy weeks and paces the rest to your deadlines, with flashcards and quizzes generated from your actual course content — structure operations, runtimes, and all. It's free to start.

How Fennie helps with CS-300
Upload the CS-300 syllabus and Fennie's Daily Plans split each module between implementation work and analysis practice, front-loading the BST and hash-table weeks that students consistently report as the heaviest. Chat through Big-O reasoning with your own examples until it sticks, and drill flashcards on structure operations and their runtimes before the final project's written analysis.
FAQ
Is SNHU CS-300 hard?
It has that reputation, yes. The combination of C++ implementation, pseudocode design work, and Big-O analysis makes it the heaviest course before the 300-level projects. Steady weekly effort matters more here than in any earlier course.
What is the CS-300 final project?
The ABCU advising assistance program: load a course list from a file into a data structure you choose (vector, hash table, or BST), print sorted course information, and justify your choice with runtime analysis in a written document.
How do I study for CS-300?
Don't just complete the labs — for each structure, be able to state insert/search runtimes and why. Writing pseudocode before code is graded directly, so practice it. A day-by-day plan through the BST weeks beats a weekend cram every time.

CS-210 — Programming Languages
CS-210 introduces C++ and compares how different languages handle the same problems, sitting early in SNHU's CS core after IT-140 and IT-145. The signature project is the Corner Grocer item-tracking program, which reads a file and reports item frequencies using maps.
CS-250 — Software Development Lifecycle
CS-250 covers the software development lifecycle with a heavy focus on Agile and Scrum — roles, ceremonies, user stories, and how requirements become working software. There's little programming; assignments are mostly written analyses of a case-study development team.
CS-320 — Software Test, Automation QA
CS-320 teaches software testing in Java: unit tests with JUnit, requirements-based test design, and basic QA strategy. Across the term you build and test three small services — contact, task, and appointment — then reflect on your testing approach in a final summary.
CS-330 — Computational Graphics and Visualization
CS-330 is SNHU's OpenGL course: you spend the entire 8 weeks building one 3D scene in C++ that recreates a real photo, adding geometry, textures, lighting, and camera controls milestone by milestone. It's one of the last courses in the CS program and assumes solid C++ from CS-210 and CS-300.
