Honest Timelines
| Your background | Weekly hours | Job-ready in |
|---|---|---|
| CS/IT student | 10–12 | 3–4 months |
| Non-CS graduate | 8–10 | 5–6 months |
| Working professional | 6–8 | 6–8 months |
| Excel-only user | 6–8 | 5–7 months |
What Each Month Should Deliver
- Month 1: Python + SQL alive (50 problems).
- Month 2: 1 dashboard + Pandas fluency.
- Month 3–4: ML basics + 2nd project.
- Month 5–6: mocks + referrals + offers.
Beware Both Extremes
"2-week data science" = scam; "2-year program" = padded. 4–6 months live + practice is the job-ready band. DSWallah plans run 3–9 months by depth — see week-by-week syllabus.
Worked ROI Example (Real Numbers)
Course ₹6,999 + 6 months × 10 hrs/week → analyst offer ₹5 LPA (₹41k/month). Payback: under 1 month of salary. Even a ₹20k course pays back in month one. The expensive input is time — protect it with live batches and deadlines.
Go / No-Go Checklist (Need 6/8 Yes)
- I can give 8–10 hrs/week for 6 months?
- I enjoy puzzles/tables more than rote theory?
- I will publish 3+ GitHub projects?
- I will do 5+ mock interviews?
- I accept starting ₹3–6 LPA and growing?
- I have a laptop + internet?
- I will ask doubts (not stay silent)?
- I start this month, not "someday"?
What I Would Do With Different Budgets
| Budget | Best move | Why |
|---|---|---|
| ₹0 | SQL (free) + 1 dashboard + library discipline, 4 months | Skill first; pay later from salary |
| ₹5–10k | DSWallah Basic/Skill-Dev live batch | Mentor + deadlines beat solo willpower |
| ₹20–30k | Job Ready / Data+GenAI track + mocks | Placement process is the product |
| ₹60k+ | Only if it adds verifiable network + tiny batches | Price must buy proof, not logo |
Final Filter: 3 Questions
- Will I finish? (live batches + refunds protect you)
- Will I have proof? (GitHub > certificate)
- Will anyone refer me? (alumni network > brochure)
Frequently Asked Questions
- Fastest realistic timeline?
3–4 months full-time with CS background + daily projects. - Part-time possible?
Yes — evening/weekend batches stretch to 6–8 months. - Does duration affect salary?
Portfolio does, not months. 6-month GitHub beats 12-month certificates.
