How to Choose UIUC Professors Using GPA Data, Syllabi, Reddit, and Rate My Professors
A source-by-source method for separating easy grading, clear teaching, course logistics, outdated reviews, and genuine instructor fit
This is an excerpt from The Jailbroken Guide to the University.
Choose a UIUC professor by triangulating five things: the current section in Course Explorer, a recent syllabus, historical grade distributions for the same course, repeated themes in student accounts, and your own first-week observation. Do not select the highest GPA or star rating automatically. The best section is the one whose teaching, assessments, pace, support, and meeting time fit how you will actually learn that subject.

Students search for this because no single database answers the real question. A June 2026 r/UIUC post asks for first-year aerospace professor suggestions after finding little in existing reviews. Another recent post describes registration research across GPA disparity, Rate My Professors, Reddit, and Course Explorer. Each source measures a different shadow of the classroom.
Start with the professor, but define what “good” means
5.2 Interesting Professors Over Everything Else
Find out who the most interesting professors are and what they’re teaching, then take their classes officially, or just show up. Inspiration goes a long way, and as long as a professor has that spark within themselves, it won’t matter what they’re teaching.
“Interesting” is like love: you’ll know it when you see it. They’re excited, curious, and they give you new ideas and energy every time you talk to them.
Great teachers matter way more than the subjects. Having one awesome professor every semester makes your life better.
What else should you keep in mind?
• How interesting the professor is (and how interesting you find the topic)
• How interesting the people in the class are
5.3 On Bullshit Classes
Don’t take bullshit classes to improve your GPA. Some Gen Eds are cool, but many are straight-up empty.
Websites like the Grade Disparity between sections at UIUC are overrated. Take classes you actually care about and want to learn more from, not the ones that would get you the easiest grade.
The grade disparity website is still useful to help you distinguish between sections and to help you find who the best professor actually is. Hint: The best professor isn’t always the one with the highest average GPA. There’s a reason for this. If you want to know what it is, keep reading.
“Good professor” can mean clear explanations, fair assessments, useful feedback, energy, accessible help, or lenient grading. Decide which two matter most for this course. In a difficult prerequisite, clarity and support may dominate. For an 8 a.m. section you will skip, none of the reviews matter.
Read the sources in the right order
1. Course Explorer: verify the class that exists now
Use the current Illinois Course Explorer to confirm the instructor, meeting pattern, location, linked components, restrictions, and part of term. Reviews for an older or online version may describe a different course. Coordinated sections may also share assessments.
2. The syllabus: inspect the operating system
Find a recent syllabus through the department, course site, instructor page, or a respectful email. Record assessment weights, attendance, late-work rules, dropped scores, collaboration policies, office hours, and weekly deadlines. It will show whether one bad midterm is recoverable and whether a lab creates a second workload stream.
3. Grade data: measure outcomes without inventing causes
The university’s Grade Distribution Dashboard provides aggregate grades by term, instructor, course, section, and schedule type. A higher average might reflect teaching, grading, self-selection, format, or sample size. Compare the same course across several terms and ignore tiny samples.
4. Student reviews: extract repeated observations
Rate My Professors and Reddit are best for repeated, concrete observations about organization, exam alignment, feedback, attendance, project time, and office hours. Discard reviews that only report a grade, insult the instructor, or omit the course and term. Three specific descriptions of one practice beat a hundred “easy” or “awful” labels.
5. Teaching-recognition lists: a positive clue, not a guarantee
Illinois publishes historical Teachers Ranked as Excellent lists. The former ICES system is retired, and CITL preserves annual historical lists through 2025. Inclusion is a positive clue from a particular period, not a guarantee of future fit.
Score fit instead of chasing a ranking
Create a small table for each available section and score these from one to five:
- Factor: Teaching clarity · Question: Do multiple recent sources describe explanations and examples as clear?
- Factor: Assessment fit · Question: Does the syllabus reward the way you can practice consistently?
- Factor: Support · Question: Are office hours, TAs, review materials, and feedback usable?
- Factor: Intellectual pull · Question: Does the instructor make you want to keep thinking after class?
- Factor: Schedule reality · Question: Will you attend this time and reach the room reliably?
- Factor: Evidence quality · Question: Are your sources current, course-specific, and repeated?
Do not combine the scores mechanically. Write one sentence: “I prefer Section A because…” If the sentence only says “the GPA is higher,” the research is unfinished.
5.28 Don’t Use the GPA Website
Websites like the Grade disparity between sections at UIUC are overrated. Focus on taking the classes that genuinely interest you, rather than those that promise the easiest grade.
The majority of today’s students will take the easy A over “risking” their GPA in order to actually learn something.
— Geoffrey Challen, Divide and Blunder
The actionable point is not to let one aggregate number choose the course. A grade dashboard cannot establish instructor motive, teaching quality, or rigor. Use it for comparison, then look for direct evidence in the syllabus and classroom.
Use the first week as the final interview
5.4 Treat Classes Like a Menu
After the first day of the semester, you have two weeks to register for your classes. I always signed up for classes on the last day. Don’t stress about signing up months in advance or obsessing over seat counts. You have plenty of time. You can wait.
During the first two weeks, go to whatever seems interesting.
Think of classes like a menu. You don’t have to commit the moment you sit down. You’re allowed to look around, skim, and try a few things before ordering. Some dishes sound good on paper but aren’t great once you taste them. Others don’t look exciting until you actually try them.
The mistake is picking something just because it’s easy or fills a requirement. That’s like ordering the cheapest item and eating it every day without thinking. Instead, use the first couple of weeks to sample classes and pay attention to specific signals: whether the professor thinks clearly, whether the material connects to things you care about, and whether you leave with new questions.
Sit in, listen, and see how the class feels. If it’s boring, move on. If it pulls you in, keep it.
The excerpt’s “two weeks” is not a current campus-wide deadline. Fall 2026 full-term undergraduate adds close in Self-Service on September 4, the tenth day, while eight-week and nonstandard courses differ; use the Registrar’s part-of-term deadline for the exact section. Ask the instructor before sitting in on a course in which you are not enrolled. During the first meetings you may attend, watch whether the instructor explains why, not only what; whether questions improve the room; and whether you leave knowing how to practice. If another section is legitimately available, compare it before changing anything.
The best professor is not a universal winner. It is the person whose classroom makes serious work possible for you in this course, this semester, at this point in your education.
