Part 4: How to Actually Learn CS

Master the art of learning computer science and develop effective study strategies.

Studying computer science is different from cramming facts for a history exam. You're not just memorizing, you're building mental muscles for problem-solving, logic, and pattern recognition.

Let's talk about how to make that easier and more enjoyable (or at least less frustrating).

12. Learn How to Learn CS

When your code breaks (and it will), you need to think like a detective.

Instead of panicking or blaming yourself, ask:

  • What's happening?
  • What did I expect to happen?
  • Where do those two diverge?

Learning to trace the logic of a program, even if you didn't write it is a major part of your CS journey. Debugging teaches you how to read code, not just write it.

Start treating bugs as puzzles, not failures.

Problem-Solving First, Syntax Second

When you're learning something new, don't obsess over remembering every semicolon or keyword.

Focus first on:

  • What is the problem asking?
  • How would I solve this without code?
  • What's the rough logic or flow?

Once you have a plan, then figure out the syntax. It's easier to translate a solution into code than to "code your way" into a solution.

Think first, type later.

Also it's totally fine to use AI tools like ChatGPT or Copilot to check your logic, get unstuck, or understand a concept. But depending on them too much can backfire. If you skip the thinking and just copy answers, it'll catch up to you when the real tests and interviews hit. Use AI like a tutor, not a crutch.

Memory Hacks That Actually Help

CS is logic-heavy, but there are still facts to remember like how loops work, or what a function does.

Here are some study methods that work well:

  • Active Recall
    Don't just reread notes. Ask yourself questions and try to answer from memory.
  • The Feynman Technique
    Pick a topic, and try to explain it like you're teaching a 10-year-old. If you can't, you've found the gap in your understanding.
  • Spaced Repetition
    Use flashcard apps like Anki or create your own notes and review key ideas over time not all at once.
  • Code-First Learning
    Read a new concept, then try using it in a small snippet or playground project.

The best learning is hands-on and slightly uncomfortable. If you feel like you're guessing, you're probably learning.

CS Is Not Just About Coding

Don't fall into the trap of thinking CS is just about writing programs. It's also about understanding the systems behind them.

You'll run into:

  • Math-heavy courses like Discrete Mathematics, Probability, and Linear Algebra
  • Logic and proofs that feel more like puzzles than equations
  • Theory-focused subjects like Algorithms or Automata
  • Hardware-related topics like Digital Logic or Computer Architecture

It's okay if these parts feel foreign or tough. CS is a broad field and not everyone excels in every area right away. But the non-coding stuff teaches you how computers work, and that's essential for building solid mental models later on.

Treat it like learning a new language: at first it's clumsy, but over time it clicks.

Working on "Hard" Problems Without Giving Up

Everyone hits walls in CS. Even experienced devs get stuck.

Here's what helps:

  • Break the problem down - smaller parts are less scary
  • Rubber ducking - explain your issue out loud to anything (yes, even a rubber duck)
  • Step away - a short break or a walk can bring clarity
  • Work with others - sometimes you need a second brain
  • Google it - seriously, it's not cheating

Progress in CS often feels non-linear. One day, everything clicks. Until then, frustration is part of the process. Learn to sit with it, and push through bit by bit.

TL;DR: CS isn't about being a genius, it's about being persistent, curious, and okay with failing forward.

13. Asking for Help Without Feeling Dumb

Here's the truth: everyone needs help in CS. Yes, even the people who seem like they have it all figured out.

But a lot of beginners hesitate to ask questions because they're afraid of looking stupid. The real mistake? Not asking at all.

Let's break down how to ask for help the right way, without the shame spiral.

Ask Good Questions, Get Good Answers

When you say, "My code isn't working," no one knows where to start. But when you say:

"Hey, I'm trying to write a function that finds duplicates in a list. It works for some inputs but fails when the list has mixed data types. Here's the code I wrote..."

Suddenly, you're giving context, and people can actually help.

The gold standard here is a Minimal Reproducible Example (MRE). It just means:

  • Share only the code that causes the issue (no extra clutter)
  • Describe what the code is supposed to do
  • Explain what actually happens instead

You don't have to be perfect but you just need to be clear.

Where to Ask

Stack Overflow

It can seem intimidating at first, but it's the place for technical answers. If you're stuck on an error, someone probably asked about it before.

Before posting, search for your issue. If you do post, be detailed and specific.

And if you run into a problem no one has asked about on Stack Overflow? Congrats, you've unlocked a real CS puzzle. Good luck, soldier.

Reddit

Subs like r/learnprogramming or r/csmajors are full of students like you.
It's more casual, and you'll often find people sharing real experiences, resources, and beginner-friendly advice.

AI Tools

Sometimes you just need a quick explanation, an error decoded, or someone to rubber-duck with AI tools like ChatGPT, Claude, or even Gemini can help:

  • Break down errors in simple terms
  • Explain concepts you're stuck on
  • Help brainstorm how to approach a problem

Just remember: don't let AI think for you, instead use it to refine your thinking, not replace it.

Official Docs and Guides

It's tempting to avoid documentation, but once you get used to reading it, it becomes your best friend. It's where all the real, up-to-date stuff lives even if it takes a few reads to click.

Ask the People Around You

Don't Shy Away from Professors or TAs

They might seem intimidating, but they're literally paid to help you learn.
If they have office hours, that's your golden ticket. Show up, ask questions (even if they seem basic), and get clarity from the people grading your work.

Your Friends and Seniors

Sometimes your best resource is someone who just did the same assignment last semester. Ask your batchmates, or reach out to a friendly senior who seems chill. Don't overthink it. Most people are happy to help if you're putting in effort and not just trying to offload work.

"I don't get this" is a valid question.
Asking shows you're trying. Staying quiet just slows you down.

Starting your CS degree can feel like being dropped into a game with no tutorial. Suddenly, you're hearing words like "object-oriented programming," "recursion," and "truth tables," and wondering what you've signed up for.

Let's walk through what your first year might actually look like, and how to not just survive it, but maybe even enjoy parts of it.

What to Expect in Courses

In your first semester, expect a mix of:

  • Programming Fundamentals — Your first real exposure to writing code. You'll build logic, mess up loops, and debug like your life depends on it. This is where your "CS" journey visibly starts.
  • IT Workshop-type Classes — You might be introduced to basic tools, OS commands, or productivity tech. These help you get used to the development environment.
  • Mathematics — Discrete Math is the usual suspect. Expect topics like logic, sets, functions, and proofs. It feels like abstract math, but it lays the groundwork for everything from algorithms to security.
  • Digital Design / Circuits — A taste of electronics. You'll learn how computers work at the gate and flip-flop level. It'll be weird if you've never done electronics before, but trust the process.
  • Soft Skills or Communication Courses — Yes, these matter. You'll have presentations, write-ups, and discussions. All of which help when it's time to explain your code to a real person.
  • A Foreign Language or Humanities Course — Sometimes you just need a change of pace. And yes, these do count in your grade.

I personally only started realizing how everything connects toward the end of my second semester. Things will click slowly. Don't rush it.

How Labs, Assignments, and Evaluations Work

Here's what the rhythm usually looks like:

  • Labs come with continuous evaluations, lab exams, and vivas. It's not just about submitting working code, you'll have to explain it too.
  • Assignments and Quizzes usually have combined marks. How many quizzes or assignments you get, and how the weight is split? That's entirely up to your professor.
  • Theory Courses may seem simple until the first midsem knocks you off your seat. Keep steady.

And yes, always do the practical, even if you feel like you've got it under your belt. That confidence fades real fast during the viva.

Do not miss out on your assignments or quizzes, they do carry a certain amount of weight.

College Is a Reset Button

This is the best time to reinvent yourself. You get to decide who you want to be, not just academically but socially too.

  • Join clubs, even if you think you won't "fit in"
  • Attend events, it helps you stay in touch with what's happening
  • Talk to people, the conversations you have outside class often teach you more than the ones inside
  • Eat more than just cup noodles. Your stomach (and grades) will thank you.

TL;DR: Your first year is a mess, and that's normal. Just stay consistent, stay open to learning, and get involved. The CS part will come together as you go.
