Software Design - the course where UofT CS students stop writing scripts and start engineering software.
Java OOP, data structures, design patterns - I build these systems at work. I'll show you how they actually fit together.
✨ First Hour FREE!
Students coming from CSC148 know Python objects, but Java OOP is stricter - interfaces, abstract classes, type hierarchies, access modifiers. The rules feel arbitrary until you see why they exist in large codebases.
Observer, Composite, Decorator - reading about them makes sense. Knowing when and why to apply them in your own assignments is a different skill. Most students memorize the pattern but can't recognize where to use it.
Linked lists, trees, and recursive traversals require thinking in pointers and references - not indexes. Students who aced Python lists hit a wall when they need to mutate a linked list in-place or traverse a BST recursively.
AI is genuinely good at Java. It will hand you a working Observer implementation in seconds. The catch is that CSC207 is not marked on whether the code runs, it is marked on whether the design was the right call, and that part is not something AI can hand you.
The project compiles and the tests pass. Then comes the question: why an interface instead of an abstract class, why Composite here, what breaks when a new type is added next sprint. A generated design leaves you with nothing to say.
Design questions are standard in internships, and they are all why questions. Nobody asks you to reproduce code from memory. They ask you to justify structure, and you cannot justify a structure you did not choose.
We start from the design decision, not the implementation. You pick the pattern and defend it out loud, then you write it. AI stays in the loop to review and challenge your design, which is what it is genuinely good at.
None of this makes you a bad student. It makes you a student learning to code in the AI era.
I use these patterns at work every day. When I explain Observer, I show you how it powers event systems in production apps. When we cover generics, you see how Java collections actually use them. Context makes concepts stick.
Every data structure session starts with a diagram. We draw the nodes, the references, the traversal paths - then we translate directly into code. Students who draw linked lists first never mix up next-pointer logic.
CSC207 assignments test the exact OOP concepts from lecture. We work through your actual assignments together - I explain the design decisions, you write the code. You learn patterns through real deliverables, not toy examples.
CSC207 is your first taste of how professional software is structured. I connect what you learn to Java Spring, Android development, and backend systems - so you understand why employers care about whether you know OOP properly.
CSC207 is the foundation for every upper-year software engineering course. Get it right now - book a free first session.

More different than you expect. Java is statically typed, strictly OOP, and has no dynamic duck-typing. The syntax is more verbose, but the payoff is that you learn to think in types and interfaces - which is exactly how production backend systems work.

Yes - this is exactly where a session pays off fast. We will map the required design pattern onto your assignment structure in the first 20 minutes. Message me now and we will book a slot today.
Directly. Java OOP, data structures, and design patterns are core interview topics at every software company. CSC207 builds the foundations that technical interviewers test. Solid CSC207 knowledge translates to real interview confidence.
CSC207 is a prerequisite or co-requisite for CSC301 (Software Engineering), CSC343 (Databases), CSC369 (Operating Systems), and many 300/400-level CS courses. Getting it right now pays dividends for two more years of your degree.
For now it probably does, and there is no shame in that. But CSC207 is graded on design reasoning, and so are internship interviews, and neither of those is something AI can carry for you in the room. Make the design decision yourself, let AI review it and argue with it, and you keep the speed without ending up with a project you cannot explain. The free AI Coding Dependency Test will show you where the line currently sits.
