How to Build a Conflict-Free Class Schedule at CU Boulder
1. Start with what's required, not what looks fun
Every term you have a handful of non-negotiable courses: major requirements, prerequisites that gate next-term classes, and any general-education requirements with a hard sequence. Build the schedule around those first. Fill the remaining slots with electives, gen-eds, or interest-driven courses — in that order of flexibility.
On CU Boulder, prerequisite chains are strict: you cannot enroll in a course whose prereq you haven't satisfied (or taken concurrently, in some cases). DegreeDraft surfaces the prereq text on every course page — read it before adding the course to your schedule, not after.
2. Pick a credit load you can actually sustain
Full-time enrollment at CU Boulder is 12 credits. The typical bachelor's-degree pace is 15 credits per term to graduate in four years. 18 is the standard maximum; beyond that requires petitioning the dean. The Department of Education rule of thumb — and the CU Boulder advising norm — is 2–3 hours of out-of-class work per credit, per week. A 15-credit schedule is a 45-hour work week including class time. Budget accordingly.
Students working 20+ hours, doing research, or carrying labs often do better at 12–14 credits. There's no prize for overloading — you can always add a summer course cheaper and with a lower grade-risk than cramming it into a fall or spring.
3. Balance difficulty across the week
Don't stack four high-difficulty courses in one term. Browse easiest courses at CU Boulder and aim for a mix — at least one low-workload elective alongside the heavy requirements. Difficulty stacks: three 4-credit courses that each demand 10+ hours per week outside class will leave you unable to do any of them well.
Use the DegreeDraft FCQ-smoothed difficulty scores as a first filter. They're Bayesian-smoothed against the campus-wide mean so low-sample averages don't mislead. Pair a known-hard course (e.g., differential equations) with a known-light one (a 3-credit elective with a difficulty score below 2.5) to balance the week.
4. Let DegreeDraft do the conflict math
Manually checking whether five courses have a conflict-free combination is error-prone. DegreeDraft enumerates every valid combination — one section per course — and filters out any combination with a time overlap. You see every legal schedule on a weekly calendar grid and can sort by earliest start time or total on-campus time.
The builder respects course components (lecture + recitation + lab in whatever combination the course uses) — you can't accidentally enroll in only part of a course. If a course has three required components, the schedule must include one section of each.
5. Pick a pacing that matches how you actually work
Back-to-back days (three or four days of class, the rest free) concentrate studying into blocks but can be draining on class days. Distributed schedules (classes Monday through Friday, shorter days) give you steadier workflow but less large-block time. Neither is wrong — pick the one that matches your actual study habits.
Gaps between classes are a feature, not a bug. A 90-minute gap is a reliable study block; a 30-minute gap is rarely productive and tends to get absorbed by phone or snack runs. Sort the generated schedules by total on-campus time to find the shapes that work.
6. Share your schedule before registering
DegreeDraft schedules are shareable — send the link to your advisor, a friend, or a parent for a sanity check before you hit enroll. Shared schedules render the same weekly grid, so anyone on the receiving end can see exactly what you're planning without needing to sign in to DegreeDraft.
Opt-in public sharing additionally lists your schedule in the DegreeDraft sitemap — useful if you're in a student group comparing plans. It's off by default; turn it on per-schedule in settings.

Credit-load norms cited here follow the U.S. Department of Education's 2-hour-per-credit out-of-class expectation and CU Boulder academic advising guidance. DegreeDraft is not an advising service — always confirm major requirements, prereq chains, and graduation plans with your CU Boulder academic advisor.
