The paid half of the free 90-day roadmap
The roadmap tells you what to build on day 24 and what done looks like. This is the part where I sit down and actually build it with you. System Design including LLD, plus DSA taught as a thought process rather than a code dump.
7 days to ask for your money back on your first payment. No auto-renewal.
Counts come straight from what is published, so this number moves when I add lessons and never sits here as a stale marketing figure.
The HLD spine of the roadmap, phase by phase, plus a full LLD module: parking lot, elevator, LRU cache, Splitwise, vending machine, movie tickets, concurrency, and the pattern families that actually show up. Every worked interview problem the roadmap points at lives here.
Every lesson ends with what you gave up by choosing it.
Pattern first, then a desi way to think about it, then the brute force, then the real answer. Solutions sit behind flaps so you can stop reading and go try it. Reference code in Java, C#, TypeScript, and Python. LeetCode links stay free on the roadmap.
Quizzes on the problems, so you find out what did not stick.
Read before you pay
These two are the full lessons, not trimmed previews. The rest of the DSA and LLD write-ups stay behind the pack. If the writing does not suit you, you will know in ten minutes and you will have spent nothing.
Nobody finishes a few hundred pieces of writing in 30 days, and I am not going to pretend otherwise. The roadmap is free forever. You do not need this pack to follow it.
Buy it for the stretch you are actually in. Most people take it for the LLD weeks, or for the HLD weeks when the design rounds get close. When 30 days are up, access stops and nothing charges you again. Pay for another block whenever you want one.
Your progress is not part of the deal. Roadmap ticks, redo queue, start date, and lesson completion all stay on your account whether you are paying or not, so coming back later picks up where you stopped.
The pack is closed at the moment. The 90-day roadmap and the free lessons stay open, so start there and check back.
Open the free roadmapStraight answers
The roadmap is free forever, so you can follow all 90 days without paying anything. The pack is the worked answers, and you pay for it in 30-day blocks. Most people do not need it for all 90 days. They buy it for the stretch they are actually in, usually the LLD weeks or the HLD weeks, then pay again later if they want another block. There is no auto-renewal and no subscription to cancel.
You lose access to the paid lessons and problems. Nothing else goes away. Your roadmap ticks, your redo queue, your start date, and your lesson progress all stay on your account, so paying again later picks up exactly where you left off.
System Design on its own is 299 rupees. DSA is not sold on its own at all. The pack is 499 rupees and gives you both, so it is cheaper than buying two paths and you do not have to guess which gap matters more.
Yes. There is a free sample of both halves on this page: one full DSA lesson and one full LLD write-up, the same text a buyer gets. The rest of those two tracks stay behind the pack. Twelve System Design lessons are free as well. If the writing does not suit you, you will know before you pay.
No. The cohort is live teaching with mock interviews and a mentor reviewing your designs, and it costs a lot more. The pack is written material you work through on your own. If you want feedback on your thinking, the cohort or a 1:1 is the right thing to buy.
Ask for a refund within 7 days of your first payment and you get your money back. Write in, no form to fill and no reason needed.
Ask within 7 days of your first payment and you get a full refund. Later blocks are not refundable, because by then you have read the material. Full policy on the legal page.
