PathSync Student
Learn it. See it run. Prove it.
A roadmap for your target role, Visual lessons and Dry Run for the hard parts, and a Career Readiness Index that only counts verified work.
Start as a student

Roadmap
A skill graph for the job you want.
Answer a few profile questions, choose a target role and company, and PathSync generates a phase spine: goal, phases, projects and milestones, ending in a final AI interview.
- Open one phase at a time; its topics are generated when you need them
- Each topic has an overview, resources, notes and a tutor
- A daily plan shows today, backlog and upcoming work
- Change your target and the path adapts

Assessments
Pass to unlock. No shortcuts.
A node is complete only when every assessment on it is passed — question papers and coding tasks. There is no button to tick a topic off.
- Question papers with a question map and flags for review
- Coding assessments inside the roadmap
- Finish the path to unlock the gated final interview


Visual
DSA and LLD you can watch.
Type any topic — “BFS on this graph”, “stack push and pop”, “parking lot design” — and Visual builds a stepped lesson. The board, the highlighted code line and the state update together.
- Graphs, queues, stacks, linked lists, trees, searching and sorting
- Low-level design boards for classes and objects
- Play, pause or step; every step explains what changed
Binary search for 23
Step 1lo = 0, hi = n - 1while lo <= hi:mid = (lo + hi) // 2if a[mid] == target: return midif a[mid] < target: lo = mid + 1else: hi = mid - 1
lo = 0 · hi = 9 · mid = —
Search for 23 in a sorted array.
Low-level design
Design problems, made concrete.
LLD lessons show the objects and their state as the scenario plays out, next to the code that drives them.
- Object state panel per step
- Concept code with the current line highlighted


Dry Run
Trace your own code.
Paste Python or JavaScript and Dry Run executes it step by step, showing the line, the variables and the output, with a short summary of what the program does.
- Works on your own snippets, not just examples
- Variables and output update on every step
- A plain-language summary at the end
1function sum(n) {2 let total = 0;3 for (let i = 1; i <= n; i++) {4 total += i;5 }6 return total;7}8console.log(sum(3));
Variables
Call sum(3).
Call stack
Output
Step 1Call sum(3).
CRI
A readiness score you can audit.
The Career Readiness Index is calculated with the cri.v1 formula from verified evidence: roadmap, DSA, projects and interviews. It is never assigned by hand, and missing work scores zero.
- Scoped to your target role
- Evidence audit shows what counted
- Recruiters see you only if you opt in
