NeetCode
Curated problem lists with video walkthroughs for every solution, plus a roadmap that shows which topics unlock which. The explanations are unusually clear, which matters when you are stuck at eleven at night.

What it is
A practice site built around curated lists, most famously the one hundred and fifty problem set, with a video explanation for each problem and a visual roadmap of topic dependencies.
Why people rate it
The explanations. A written editorial tells you the answer; a good video shows the moment where the insight arrives, which is the part you need to reproduce. The dependency roadmap is also genuinely useful, because it makes explicit that you cannot do graph problems before you can do trees.
How to use it
Attempt every problem for at least twenty five minutes before opening the video. Watching first feels efficient and teaches you almost nothing, because recognition is not recall.
Best for: self directed learners who want free structure and prefer video to prose.

Stuck on something specific?
Writing only gets you so far. If you want an answer to your situation rather than the general case, book a session and we will work through it together. Every session is free; a few slots open each week.
