REAL LESSONS. ONE STEP AT A TIME.

A little guidance.
A lot of thinking.

This is Two Sum in the Python course, as you see it in the app. Each step is a line or two of the solution, checked by the lesson’s tests before the next one appears.

WHAT YOU GET.

LeetCode Is Powerful. But It Doesn't Teach You How to Think.

If you've spent hours staring at a LeetCode problem, reading the solution, thinking "I would never have come up with that" — you're not alone. LeetCode was designed as a practice tool, not a learning tool. The difference matters more than most people realize.

The Memorization Trap

You study a problem, memorize the approach, then hit a slight variation in an interview and freeze. Memorized solutions don't transfer to new problems.

The Confidence Gap

You can follow solutions when you read them, but you can't build one yourself. Every new problem feels like starting over from zero.

No Clear Path

With 3,000+ problems and no structure, it's hard to know which problems to focus on. You end up grinding randomly and wasting hours.

Step-by-Step Tutorials

AlgoCademy breaks every problem into 3–7 small steps, each with a specific goal. You write the code yourself and get real-time feedback on exactly what's wrong.

4 Programming Languages

Whether you're using Python, JavaScript, Java, or C++, every problem includes full solutions and step-by-step tutorials in your language.

290+ Hand-Picked Problems

Focused on the patterns and problems you'll actually encounter. No random grinding — a structured path from fundamentals to advanced algorithms.

After going through all the lessons, I gained the necessary skills to perform well at my on-sites. I crushed even the DP problems, which were my biggest fear. And thanks to that I landed offers from Microsoft and Uber. Thank you AlgoCademy!
Cristina Radulescu Landed offers from Microsoft and Uber
AlgoCademy really helped me improve my problem solving skills and write incredibly clean code. I was worried it wouldn’t be done in time for my coding interviews, but the way the curriculum is structured made me progress very quickly. Thanks for your work!
Connor Holland Student story · Vanguard
Wow. I've been using AlgoCademy for a while and now I can finally solve coding questions on my own. This gave me the confidence I needed for my interviews, and guess what? I landed the offer at Samsung! You guys truly kick ass. High fives!

A FEW QUESTIONS BEFORE YOU START.

Frequently asked questions

So, you have questions? Let us try to answer those for you...
Ask the AlgoCademy team ↗

Can I use AlgoCademy alongside LeetCode?

Many students do exactly this. They use AlgoCademy to learn the step-by-step thinking process and core patterns, then move to LeetCode for additional practice once they can solve problems independently. The skills transfer directly.

I'm a complete beginner. Is this too advanced?

AlgoCademy was designed with beginners in mind. You need basic programming knowledge — variables, loops, conditionals — but you don't need prior experience with data structures or algorithms. The curriculum starts from fundamentals and builds up. Many of our most successful students were career changers with no CS degree.

What programming languages are supported?

All lessons include solutions and tutorials in Python, JavaScript, Java, and C++. The conceptual explanations focus on thinking process and pseudocode, so the skills apply regardless of your preferred language.

Is all the content available straight away, or is it drip-fed?

No drip-feeding here! You get access to everything inside AlgoCademy right away. Most students complete the curriculum in 2–4 months studying 1–2 hours daily. Go as fast or slow as you need.

How is this different from watching YouTube tutorials?

Watching someone else solve a problem feels productive but rarely is. You're passive — you follow along, nod, and forget most of it. AlgoCademy makes you write the code yourself, step by step, with real-time feedback. You're actively building the solution, which is how lasting understanding develops.

Is it really worth paying when LeetCode is mostly free?

LeetCode is free for practice. But if you've been grinding LeetCode for weeks and still can't solve problems independently, more free practice isn't the answer — better learning is. AlgoCademy's value is in closing the gap between "I can read solutions" and "I can build solutions." For most people, that's worth far more than the subscription cost relative to the salary outcome.
