UC Berkeley introductory CS failure rates spike to 35%, prompting 1,300 faculty to demand SAT and ACT reinstatement

Instructors blame AI overreliance and weak foundational math skills.

“In addition to overreliance on AI, Garcia also pointed out that many students are underprepared mathematically, a concern echoed by campus associate teaching professor Gireeja Ranade…

Both Garcia and Ranade have joined more than 1,300 UC faculty in signing a petition calling for the reinstatement of ACT and SAT standardized testing scores for STEM admissions in the UC system. The petition and its accompanying open letter detail similar concerns with students’ mathematical preparation.”

Students are failing UC Berkeley CS classes at an alarming rate. More than 35% of students failed CS 10, a course described as “a gentle but thorough introduction to computer science.” In the past few semesters, less than 10% of students failed the class.

Positive users praise UC Berkeley for upholding standards by failing students caught cheating with LLMs like Claude, while negative users blame AI overreliance for damaging learning or shift to unrelated attacks on admissions policies.

🦔UC Berkeley's computer science department just posted its worst failure rates in years. 35.3% of CS 10 students got F's in spring 2026, up from under 10% in prior semesters. Professor Dan Garcia says the primary driver is a "vast increase in academic dishonesty" through LLMs. Students use AI to complete assignments, never learn the material, then fail exams. His office hours, once full, are now empty.

My Take Companies are firing experienced engineers while the pipeline that produces new ones is being gutted by the same technology. Students use AI to bypass the hard part of learning, show up to exams without the understanding, and fail. One professor discovered a student's linear algebra class had an "open AI" policy for homework and exams. That student then couldn't do basic linear algebra in the next course.

Both ends of the workforce are eroding at the same time. Senior engineers are getting cut to fund AI spending. Junior engineers are graduating without the skills because AI did their coursework. And the companies spending trillions on these tools haven't connected those two facts yet.

college is not over. i have a few academic friends in universities and the things they are now doing with codex + pro models will shock you

Tenobrus@tenobrus

berkeley professors started getting serious about detecting and preventing ai use in intro cs classes. fuckin 35% failure rate. combination of explicitly caught cheating, inability to pass exams, and not actually having learned anything from prerequisites.

college is over man

the credential value of a college degree is dropping like a rock rn. unless the school has totally reworked their class structure and invested significant effort in preventing ai cheating there's just no reason to expect graduates learned *anything*

@tkanthh 🤷‍♂️ heavily proctored in-person exams worth 90-100% of your grade?

both ends of the pipeline eroding simultaneously is the part nobody is talking about. companies cutting senior engineers while junior engineers graduate without foundational skills because AI did their coursework is not a temporary disruption, it's a structural gap in the workforce that compounds every year the pattern continues

@HedgieMarkets we're about to have a generation of engineers who can prompt but can't think for themselves

@HedgieMarkets My failure rates are going up as well. However, students who want to cheat have always found ways to cheat. AI lowers the barrier so perhaps there is some marginal propensity to cheat being accessed here, but I don't think it can explain a move like this.

@ishaansehgal 🦔And when the pricing changes or the tool goes down, there's no fallback. You can't troubleshoot what you never understood in the first place.

@tenobrus Definitely need to rework assessment (e.g. for me assessment is now based on in-class/oral exams). Big challenge for students to understand you’ll fail the exams if you have AI do the (not-for-credit) HW. That said so far this strategy seems to work in upper-level math classes.

@tenobrus Maybe I'm already permablackpilled on college but 35% seems surprisingly low

@Dr_Gingerballs 🦔The difference is friction. Copying an answer key took effort and carried risk. Pasting a prompt takes seconds and feels like studying. That drop in effort probably unlocked a whole tier of students who wouldn't have cheated otherwise.

When I went to Cal in the pre-AI era, exams were already worth 60-80% of your grade. And they were handwritten coding exercises.

Maybe in the interim they switched to machine proctored versions, but it seems like you can simply switch back and there would be enough back pressure.

@tenobrus “College is over” because we have no clue what white collar work will look like in 10 years. What should CS students even be learning right now?

@HedgieMarkets This is catastrophic for humanity, rather than augmenting our intelligence, it is stripping us of it. It is an utter disaster.

@_vish_k only at schools where the failing grades actually go up

@HedgieMarkets cutting seniors to fund AI, graduating juniors who can't code without it. nobody's mapped those two decisions onto the same org chart yet
