Craig deserves a promotion, he is one of the best staff in C3s , always useful and helpful .
Craig was very welcoming and assistive with all questions and problems I have. I received nothing but kindness and honesty. I appreciate the most how he greets me with a smile each time I come for class and ensures that I’m updated on everything school wise. He is very professional and is always giving me guidance even if it’s not related to school situations.
Craig is amazing and has made my experience in this school an amazing one
There is a lot to love about C3S; but what got to me most was the super friendly staff!! Literally everyone straight from the receptionists to the lecturers. They're all so nice and welcoming, and they make you feel so comfortable 😊. Also, the classes are not hectic, they're flexible, and the lecturers provide such a friendly and enjoyable learning experience.
If possible, I’d rate this school zero stars — which is exactly what it deserves (0/5)
have been in the academic field for a while and, seeking to advance my studies, I chose to change my course and study in Spain.
Unfortunately, I fell for the way C3S Business School was aggressively marketed by agencies in multiple countries.
1️⃣ It’s Not a Real University
.C3S is not a university — it’s just a private “school” handing out dubious diplomas instead of accredited degrees.
• No Spanish students attend because locals know better. The absence of local enrollment speaks volumes about its reputation in Spain.
2️⃣ Exorbitant Costs & Hidden Fees
• The tuition is extremely expensive for what you get — with fees increasing from €6,800 to over €7,000 plus extra hidden registration and application fees.
• Fail one course? They’ll charge you more. Every mistake is a new fee. Their true motto: “Money first, students last.”
3️⃣ Abusive Academic System
• The grading system is unfair and biased — many students have witnessed how your grade depends on whether a teacher likes you, not your work.
• If you want good grades, prepare to be a teacher’s pet or fit their personal preference — merit does not matter here.
• Exams are poorly planned: you can sit for your first major exam after only two months, then another critical exam the next month that determines whether you pass the entire semester — fail that, and you fail everything.
• Class schedules are irregular, frequently changing without notice. Professors often don’t show up — and you’re forced to retake missed classes at your expense.
4️⃣ Inadequate Facilities
• There is no campus, just a cramped building with no cafeteria and only two bathrooms for approximately 400 students — unacceptable.
• The environment is unwelcoming and feels more like a restrictive high school than a place for mature learning.
5️⃣ Empty Promises & False Advertising
• Webinars are mandatory yet useless — missing them slashes your attendance grade, but attending them does nothing for your future.
• They promise networking and community, but there is none. Students are forced to show up at staged events so the school can post photos online and look good on Instagram.
6️⃣ Poor Management & Student Support
• Administrative mistakes are serious and frequent — from lost papers to false failure claims, you’ll be forced to prove your innocence if they mishandle your grades.
• There is no help or real student support — once you enroll, you’re on your own against the same staff who are supposed to guide you.
• The visa process is a nightmare — disorganized and stressful.
7️⃣ No Student Life or Community
• There’s no accommodation, no proper welcoming system, and no real student community.
• Most people don’t make friends because the environment is cold, cliquish, and driven by profit rather than care.
🚨Final Words — Come Here at Your Own Risk
I came to Spain hopeful, having done my research, reading both good and bad reviews. Sadly, I ignored the warnings — the positive reviews are from students bribed with extra credit to write them.
C3S Business School is, without exaggeration, the worst educational experience I have ever witnessed. It is a system that exists only to extract money, not to educate or support. They treat students like high school children who must earn “respect” instead of fostering a welcoming learning environment.
To make matters worse, Barcelona itself is not easy for foreigners — scams are common, the cost of living is high, and for many, life here turns out harder than what they left behind.
My heart goes out to those who can’t leave, those who feel stuck, and those who realize too late. If I HAD AN ENEMY, I WOULD wish them an enrollment at C3S Business School.
To anyone considering it: stay away. There are bad schools everywhere — but this one takes pride in it. They operate like a business, not an educational institution, and they run their students down with pressure, fees, and manipulation.
I hope one day this place is shut down for good for failing its students so completely.
Come here at your own risk — or better yet, don’t come at all.
