Your preparation ground
Prepare by seeing
how it actually works.
Algorithms, low-level design, networking, operating systems and databases, each animated one step at a time, plus full video courses with your notes beside them. Then practise with sheets, timed mocks and a roadmap built around the days you have. One ground. Everything on the syllabus.

How it works
Watch it. Compare it. Prove it. Plan the next one.
Every subject here is taught the same way, so once you have learnt one track you already know how to learn the rest.
- 01
Watch it move
Press play. Pointers glide, packets cross the wire, a scheduler switches context. Every step is narrated and every line of pseudocode lights up as it runs.
- 02
Compare approaches
Brute force sits next to the optimal answer on every problem. Jump between them and watch the time and space cost fall.
- 03
Prove you can do it
Write the approach in your own words and get it graded. A problem only counts as solved when the optimised version passes.
- 04
Plan the next thing
Tell the roadmap what you want to learn and the days you have; it drafts the syllabus and serves one honest list each morning.
Learn
Every subject on the syllabus, taught visually.
DSA is free to start. One plan unlocks every track, sheet and roadmap.
DSA Visual
Algorithms animated step by step: brute force first, then the optimal trick.
LLD Visual
Object-oriented design with class and sequence diagrams that draw themselves.
Networking
From a single fetch() down to bits on the wire and back through TCP, DNS and TLS.
Operating Systems
Processes, scheduling, memory and file systems, how the machine runs your code.
Databases
ER design to B+ trees, query plans, transactions and recovery.
Video Courses
Full YouTube playlists, watched here, with your notes and code saved beside every video.
Practice & plan
Then prove it under the clock.
Practice Sheets
One topic at a time, every problem linked to LeetCode and solved in C++, Java and Python.
Aptitude Mocks
Timed placement-standard papers across eight categories, with worked answers.
AI Interviews
Sit the rounds companies run now: a codebase with an assistant in the room, a pull request to review, a system to design.
AI Roadmap
Name a subject and the days you have; get a syllabus and one honest list each morning.
Check every pair, two nested loops over the array.
Brute force → optimal
Never stop at the first answer.
Every problem carries its approaches side by side: the obvious one and the sharp one. Switch between them mid-animation and watch the complexity drop, so you learn the why behind the trick, not just the trick.
- Pseudocode lights up line by line as the state changes
- Time and space cost shown for every approach, every step
- Jump to any step without replaying from the start
AI Roadmap
A plan for the days you actually have.
Name any subject (DSA, JavaScript, Docker, system design) and get a syllabus drafted for your level and your minutes, ordered so nothing depends on something you have not learnt yet. Miss a day and it becomes backlog, not a broken schedule.
- Sized to the subject: seven days for linked lists, six weeks for DevOps
- Algorithm tasks open straight in the visualizer
- One list each morning, with nothing hidden in a calendar
Start on the free track. Stay for the whole ground.
Two Pointers is open to everyone, with no account needed. When you are ready, one plan opens every course, sheet, mock and roadmap.
