Aachen.

RWTH Aachen is one of Germany's top engineering universities, respected by employers but genuinely selective: no continuous assessment, just one final exam per subject, and professors who prioritise mastering the material over comfort. The reward is a location at the meeting point of Germany, Belgium and the Netherlands, plus a free region wide train pass with enrolment.

• RWTH's engineering reputation opens doors, but treat the semester like a real academic year, not a relaxing exchange.
• Aachen sits at the triple border of Germany, Belgium and the Netherlands, with Maastricht and Liège a short trip away.
• Plan a lighter course load than you would elsewhere, RWTH is known to trim down foreign students through its hardest bachelor courses.

With RWTH and the FH combined, Aachen counts well over 45,000 students, so the international crowd is large even if the workload keeps everyone busy. Erasmus students naturally cluster together to survive the credit crunch, swapping course tips rather than partying non stop, and the scene leans more study groups than big nightlife until the semester winds down.

• Join the Studcasa Aachen group early, comparing notes on which courses are survivable matters more here than in most exchange cities.
• Expect study sessions to double as social time, the exam pressure pulls the international crowd together fast.
• Save the big nights out for after exams end, the semester itself leaves little slack.

Day to day living in Aachen runs about 15 percent cheaper than in France, and the Mensa serves a full meal for around 2 euros, a real lifeline on a student budget. The recurring surprise is the Rundfunkbeitrag, Germany's mandatory TV and radio fee, roughly 50 euros a quarter per household, triggered automatically by your Anmeldung. Split it with flatmates from day one.

• Eat at the Mensa when you can, a full meal for about 2 euros beats any supermarket dinner.
• Budget for the Rundfunkbeitrag, about 50 euros a quarter, and agree with roommates upfront on how to split it.
• Overall costs sit around 15 percent below France, but the tight housing market eats into those savings fast.

Housing is the hardest part of Aachen: over 45,000 RWTH and FH students compete for a limited supply in a mid sized city. Expect around 500 euros a month on average, up to 700 euros all inclusive for something new and fully furnished, or 200 to 450 euros in a residence or WG (shared flat) if you're lucky. WGs almost always want to meet you in person before accepting a room.

• Start your housing search the moment you're accepted, the market is genuinely tight for 45,000 plus students.
• Expect WG flatmates to insist on meeting in person, a Skype call alone won't get you the room.
• Ask the university's international office for leads, they're used to guiding exchange students through this exact scramble.

Your Semesterticket, included in enrolment, is one of Aachen's best perks: it covers buses and regional trains across all of North Rhine Westphalia, so Cologne, Düsseldorf and Bonn are free day trips. Because Aachen sits right on the border, Maastricht and Liège are also just a short ride away, even though they fall outside the ticket's free zone.

• Use the Semesterticket to explore North Rhine Westphalia for free, Cologne, Düsseldorf and Bonn all count.
• Hop the border on weekends, Maastricht and Liège are both close enough for a half day trip.
• Check the ticket's exact zone before boarding cross border trains, free coverage stops at the regional line.

Take the warnings seriously: one recent exchange student validated only 13 of 30 planned credits, despite calling themselves a strong student, and had to redo the semester back in France. Bachelor level Maschinenbau courses seem designed to filter out foreigners, so lean master level. Expect one week of revision per 10 credits, one final exam per subject, no continuous assessment.

• Choose master level courses over bachelor level Maschinenbau, the latter is notoriously used to weed out exchange students.
• Register for exams yourself as soon as you finalise your courses, RWTH never does it automatically and the deadline is strict.

It depends on your nationality. EU/EEA/Swiss students need no visa and just register locally. Non-EU students from many countries (US, UK, Canada, Australia, Japan and more) can enter visa-free and sort a residence permit after arrival; others must get a national student visa from a German consulate before travelling. Either way you'll likely prove funds via a blocked account (Sperrkonto) of around 11,900 euros a year.

After arrival, the rituals are the Anmeldung (registering your address at the Burgeramt within two weeks), German health insurance (public schemes like TK cost students around 120 euros a month), and, for non-EU students, the Aufenthaltstitel residence permit. Book appointments early; slots are scarce.

• EU/EEA/Swiss, no visa, just register your address
• US/UK/CA/AU/JP etc, enter visa-free, get residence permit after arrival
• Blocked account (Sperrkonto), ~€11,900/year
• Anmeldung at the Burgeramt within 2 weeks of moving in

Student food culture in Aachen centres on the Mensa, where a full meal costs around 2 euros, a habit most exchange students fall into fast given the workload. Outside class, the city leans practical and studious rather than flashy, matching its reputation as a serious engineering town. Pack for grey skies too, Aachen's near constant rain is a running joke among past exchange students.

• Default to the Mensa for cheap, filling meals, at about 2 euros it's hard to beat.
• Bring a real umbrella and rain jacket, Aachen's reputation for near constant rain isn't exaggerated.
• Don't expect a huge going out scene, the city and its students lean studious over flashy.

Aachen doesn't split into flashy versus rough districts like bigger German cities, so the smarter question is distance to your specific RWTH building. Staying near the compact centre keeps you close to the Mensa, shops and transport, while a room further out can save money if you don't mind a longer commute. Given how tight housing already is, take a solid offer over a perfect area.

• Weigh commute time to your specific RWTH building, campus buildings are spread across the city.
• Staying near the centre keeps you close to shops, transport and the Mensa.
• In a market this tight, take a solid offer near campus over holding out for a perfect location.

Aachen's triple border location is its biggest travel asset: Maastricht and Liège are both close enough for a half day trip, and your Semesterticket covers all of North Rhine Westphalia for free, so Cologne, Düsseldorf and Bonn cost nothing extra. Getting home to France is harder, the Lyon to Aachen train takes around 6 hours and can run close to 200 euros if booked late.

• Book any Lyon to Aachen train early, waiting until the last minute can push the price toward 200 euros.
• Use free weekends for Maastricht or Liège, both are close enough for an easy half day out.
• Ride the free Semesterticket network through North Rhine Westphalia before assuming a day trip has to cost you anything.

Book your Anmeldung appointment the moment you move in, slots fill up fast, and you can deregister remotely once you leave. Exam registration is never automatic at RWTH, you register yourself with a strict deadline, so confirm it the same week you pick your courses. Expect to redo your Learning Agreement in the first one to two weeks. Above all, don't underestimate the workload.

• Register for exams yourself as soon as you finalise your courses, the deadline is strict and RWTH won't remind you.
• Book your Anmeldung slot the day you move in, appointments book out weeks ahead.
• Take the 13 out of 30 credits warning seriously, and lean on the Studcasa Aachen group to find out which classes are actually survivable.
