Good structure, but SQL/R sections are shallow
Completed in 4 months (~15 hrs/week). Courses 1-3 (Foundations, Ask Questions, Prepare Data) are mostly theory — vocabulary, process frameworks, stakeholder management. Useful context but not technical.
Course 4 (Process Data) introduces spreadsheets pivot tables, basic cleaning. Course 5 (Analyze Data) is the SQL course — 3 weeks, covers SELECT, WHERE, JOIN, GROUP BY, subqueries. *Too little practice.* 20 exercises total. I supplemented with Mode Analytics SQL Tutorial (free) and LeetCode Easy/Medium.
Course 6 (Share Data) is Tableau. Good intro but Tableau Public (free) has limitations. Course 7 (R) — 2 weeks for a whole language? Covers basics of tidyverse, ggplot2. Not enough for real work. I took DataCamp's R track after.
Capstone (Course 8): choose from 3 case studies. Build portfolio piece. Peer-graded — quality varies. Mine got 4.8/5 but reviewers barely read.
Certificate got me interviews. But technical screen required deeper SQL + Python. Supplement heavily.
