What are the prerequisites?
Basic Python proficiency and linear algebra familiarity. Optional: prior ML exposure. If you’re rusty, start with a quick refresher on vectors, matrices, and derivatives.
How much time do courses take?
Each course lists total hours. Expect 1.5–2x that time for projects, optional readings, and reflection. If you study 4–6 hours/week, most learners progress steadily without burnout.
Do you issue certificates?
Selected courses include verifiable certificates of completion. If a course includes one, you’ll see it clearly indicated on the course page and inside your dashboard after finishing graded checkpoints.
