As a fellow Czech, who studies in one of top 20 UK universities, let me add my two cents.

As of 2020, UK universities are not worth the cost. The tuition fees alone amount to 27000 GBP (3-year undergrad) for British (non-Scottish) students with EU students now paying foreign student fees.
I am still under SAAS scheme so I don't pay a single pound, which is why I am still here. Nevertheless, the cost is too high to pay for something as uncertain as future market conditions, let alone life in general (from cancer to suddenly disliking your career choice). To make the most out of UK universities, smart students choose subjects by faculty and its professors. The best bet for Oxbridge and other is still STEM while I would be very careful with anything else. Unless the said student has a very nice liquid asset portfolio...

Currently, there are two problems in UK universities:

Firstly, the growing trend of limiting free speech and radicalisation of student on all sides of political spectrum. I witnessed my Slovak friend, who now supports views that would make Gottwald and Husak blush, while my catholic friend suddenly started to vote for open anti-semite. But that is a whole can of worms that I will let anybody else to open and examing. The issue I see now is that students and professors activelly selfcensor themselves in case of an everpresent snitch is present among their ranks (don't you dare say something against CHINA!).

Secondly, students in the UK are neither students or customers, they are lifestock. Universities now compete in monopolistic market where the quantity of students determines their profits. The quality has minimal effect on profits as due to universities international reputation, there is no shortage of students. Also due to UK government, they also operate mostly as price takers. It is not about selling education to students, but to ensure that the greatest quantity of students is processed through the university system to maximise profits. That is why university management gives priority to enlarging university premises rather than paying teaching staff a fair wage and pension, which is why many professors are striking quite regularly in the UK. In simple terms, students are not customers, but raw material that is supposed to be processed for profit. Although I am open to debate, nobody will ever convince me that an academic institution should have the total of 5 bars and nightclubs in order to achieve higher level of academic excellence. I like my beer, but my personal research never supported my hypothesis that higher volume of alcohol leads to better grades.

This is why universities in UK are being filled with pseudoscientific courses, while lowering passing grades and standards which are effects I have witnessed due to my non-academic circumstances that prolonged my degree. It is to ensure that the greatest number of students survive through the course so that the university can make money of the students from 27000 tuition + bar spending + gym spending + overpriced accomodation fees + any other unecessary bs.

FYI, the above is the reason why I am purposefully staying quite far from my university (before covid) and I do not interact with students from my university. I am there for one reason only. I love my subject and I love my professors who are amazing despite the circumstances that they work in!

For fellow Czechs, if I would have a friend who would want to go study computer engineering to Oxford, I would point them to CVUT. Less money and excellent degree! Unfortunately in my field, the education in Czechia is not on par and lacks quite behind the rest of the world...I and I have a bad feeling one day soon we will pay the price
