Great!

The scraping for course user already taken looks good. Could you make sure the shape for the courses taken look like this:

const userCourses = {
  userId: v.string(),
  courseCode: v.string(), // CSCI-UA 101
  title: v.string(),
  year: v.number(), // 2025
  term: v.union(
    v.literal("spring"),
    v.literal("summer"),
    v.literal("fall"),
    v.literal("j-term"),
  ),
  grade: v.optional(
    v.union(
      v.literal("a"),
      v.literal("a-"),
      v.literal("b+"),
      v.literal("b"),
      v.literal("b-"),
      v.literal("c+"),
      v.literal("c"),
      v.literal("c-"),
      v.literal("d+"),
      v.literal("d"),
      v.literal("p"),
      v.literal("f"),
      v.literal("w"),
    ),
  ),
};

you can ignore the userId for now I can help you set it up.

for the enrolled courses for this semester and courses in the shopping cart, you should get the following data for each record: courseCode, term, year', and section`

As we discussed last time, connect what you have so far with the backend. Let me know if you have any questions or when you are ready for review

this is not working as expected on my end. Make sure we have convex database as the source of truth and user can confirm and save to the db.
