Python for Data Science and Machine Learning Bootcamp vs Self-Driving Car Engineer Nanodegree
Same Bayesian formula, same rubric — so the difference in scores reflects the difference in the courses, not the difference in how we evaluated them.

Self-Driving Car Engineer Nanodegree
Per-criterion
The 25-hour curriculum moves from Python basics through NumPy, Pandas, Seaborn, Matplotlib, Plotly, Scikit-Learn, and closes with TensorFlow and Spark primers. Reviewers consistently praise the breadth and the quality of the accompanying Jupyter notebooks. The recurring criticism is that the machine-learning section is template-heavy — Scikit-Learn calls are shown without deep mathematical explanation — and both the deep-learning and Spark sections draw specific complaints about using outdated TensorFlow versions and lacking modern context.
Jose Portilla holds a BS and MS in Mechanical Engineering from Santa Clara University and has trained data science teams at General Electric, Cigna, Credit Suisse, McKinsey, and Starbucks. Across every source reviewed, his teaching style is the most praised element: Reddit users describe him as clear and well organised, and blog reviewers say he makes intimidating topics feel approachable. The only instructor-specific complaint is that later sections receive noticeably less polish than the Python and Pandas core.
This is a one-time Udemy purchase that routinely discounts to under $15. Reddit users call it "the best money I spent" and frame what used to cost thousands in a live bootcamp as available for a few dollars at sale. With over 400,000 students and a 4.6 average from 157,000+ ratings, the value-for-money proposition is the most consistently praised feature across all communities analysed.
Every lecture includes a detailed Jupyter notebook that learners can run and adapt for their own work. Real datasets are used throughout, and reviewers describe the notebooks as both a learning tool and a portfolio artefact. The limitation is that projects are instructor-led walkthroughs rather than independently scoped challenges, and there is no graded capstone or peer review to validate skills before entering the job market.
The hands-on Python data science stack — NumPy, Pandas, Scikit-Learn — taught here is directly used in daily analyst and data science work. Career-changers on Reddit credit the course as a pivotal step toward entering the field. The ceiling is that it does not cover model deployment, production pipelines, or MLOps. Reviewers agree that substantial follow-on study is needed before tackling meaningful real-world problems independently.
Reviewers praise the breadth — CV, sensor fusion, localisation, planning, control, ROS on Carla. The caveat is the curriculum is deep-learning-heavy and some flag this as the wrong architectural bet for real autonomous vehicles.
Sebastian Thrun, David Silver and the rotating industry instructors (Mercedes, BMW, NVIDIA, Uber ATG, Waymo alumni) get steady positive mentions. Reviewers who took the free CS373 first describe the nanodegree as a paid extension.
The biggest drag on the score. Original 2016-2017 price was ~$2,400; current pricing sits around $249-399/month, total ~$1,000-1,500. Flagged against free MIT 6.S094, MIT 6.832 and Stanford CS221/CS231n alternatives.
Original cohorts received mentor-graded project reviews and praised them highly, but later reviewers — including one of the most-cited HN voices — report Udacity "got rid of this feature" for self-paced learners. Slack community partially compensates.
Projects are unusually applied — behavioural cloning, lane finding, sensor fusion, path planning, and a final integration on Udacity's real Carla vehicle via ROS. The gap is that industry has moved past the deep-learning-heavy approach taught.
