Note: Instructor Velasco’s consulting hours aren’t limited to just homework questions. It’s also an opportunity to seek career advice, explore internship opportunities, discuss topics in computer science, get guidance on the course, and more. It is not just a space to receive help with the class but also for broader academic and professional conversations.
