Frequently Asked Questions
What are the prerequisites for beginner courses?
Comfort with basic Python and linear algebra helps, but we include primers in each beginner course to get you started quickly.
How do cohorts differ from self-paced tracks?
Cohorts include live sessions, mentor code reviews, and deadlines. Self-paced tracks have the same projects but flexible timelines and forum support.
Do you offer certificates?
Yes, we issue completion certificates that reflect practical project work. They are not formal academic credits.
Can I switch tracks after enrolling?
You can request a track change before the second module of a cohort or within 14 days for self-paced tracks, subject to availability.
What is your refund policy?
Refunds follow the policy stated at checkout and vary by program type. We aim to be fair and transparent—contact support for details.
How much time should I allocate each week?
Most learners spend 6–10 hours weekly. We include time estimates in each course to help you plan.
Do you provide one-on-one mentoring?
Yes, many tracks include optional 1:1 sessions for code reviews, architecture planning, and career guidance.
Is there corporate training?
We offer tailored programs for teams, including private cohorts and MLOps audits. Please contact us.
