Crack your dream product
company from any college.
A pattern-first placement track for students without a coding culture around them — curated sheets, core CS, aptitude and real interview breakdowns, in one sequence.
No card. The first pattern takes about 10 minutes.

● What you get
Four tracks, one sequence
Each section picks up where the last leaves off — so you always know what to open next instead of tab-hopping across five sites.
PATTERN FIRST
Graph
DSA Sheets
The curated SWE Sheet, sequenced pattern-by-pattern rather than topic-by-topic — plus a focused Last-Minute 100 for revision day.
CORE CS
SQL
Domain
SQL, DBMS and OS — the problem, the best approach and the clean answer, side by side.
MCQ DRILLS
✔
Screening
Quant aptitude and logical reasoning — crisp theory, then timed MCQ practice.
LATERAL THINKING
Puzzles
Classic interview brainteasers — logic, weighing, parity and optimisation — each with a diagram, staged hints and a worked solution.
COMMUNITY

Interview Stories
Round-by-round breakdowns from candidates who sat the loop — what got asked, what they'd do differently, and how it ended.
HOW IT WORKS
Three habits, repeated
There is no trick to this. The platform exists to make the boring version of preparation impossible to lose track of.
1.0
RECOGNISE
Learn the pattern, not the problem
Every problem in the sheet is filed under the pattern that solves it, with the cue that identifies it. You stop memorising 500 solutions and start recognising 85 shapes.

Sliding Window 9
Monotonic Stack 7
Binary Search on Answer 11
Top-K / Heap 8
Union Find 6
0/1 Knapsack 14

PRACTISE
Work the sequence in order
The sheet is ordered, not alphabetical — each problem assumes the one before it. Tick as you go and your progress, notes and bookmarks stay attached to the problem, not to a spreadsheet.

REVISE
Revise what you actually got wrong
Anything you flagged, needed a hint for, or wrote a note on comes back before your loop — and the Last-Minute 100 compresses the whole sheet into one evening.
⭐ LOVED BY LEARNERS
What our students say
Real messages from learners following the RisingBrain pattern-wise sheet.
★★★★★
“Previously I was stuck somewhere in logic. After consistently following your pattern-wise sheet, I can now write code for arrays in both brute force and optimal — it's all because of you, sister. Love from Hyderabad.”
★★★★★
“I saw your sheet on my LinkedIn feed — it's incredibly well-organised, based on patterns. Thank you for making it. I'm using it to master every pattern concept.”
★★★★★
“I've watched many DSA playlists, but I'd understand a concept and then forget how to solve the problem later. Your pattern-wise sheet is one of the best resources I've come across — it builds problem-solving step by step.”
★★★★★
“I'm a working professional in a service-based company and not a CS/IT student, but this isn't difficult to learn from you. You're actually rising our brains.”
★★★★★
“One thing I have to admire about the RisingBrain pattern-wise sheet — after learning a single problem from you, the next related one gets easily solved. Thank you for boosting my confidence.”
★★★★★
“I just love your DSA sheet and your explanation, ma'am — cracked a startup with just your sheet within one month of prep.”
QUESTIONS & ANSWERS
Frequently asked questions
Everything you need to know about the platform and getting started.
Yes. The curated SWE sheet, aptitude drills, core CS domain tracks, and practice arena are completely free forever — no card, no catch. Start solving problems right away.
Students from tier-2/3 colleges with no coding culture, working professionals switching to product roles, and anyone preparing for SDE interviews. If you have raw motivation but no roadmap, DSA Master gives you structured clarity.
Not at all. The tracks start from absolute fundamentals and build up step-by-step — your college branch or college tier doesn't decide your ceiling here.
LeetCode gives you raw problems; DSA Master gives you patterns. We sequence 500+ problems across 85 topic-wise patterns so you stop memorising solutions and start recognising problem shapes — the way top tech interviews actually test you.
The Domain track covers SQL queries & schemas, DBMS internals & transactions, Operating Systems concurrency & memory management, and Computer Networks protocols & socket models.
