I’m planning to join a MERN Stack Course and want practical, experience-based advice. What should a solid MERN Stack Course include—React routing/state, Node/Express APIs, MongoDB schema design, auth, testing, deployment, and a real capstone? How many projects are enough for a portfolio, and what topics actually help in interviews (DSA vs system basics)? Sharing via Ascents Learning—please share outcomes, challenges, and what you’d change.
