Studying in Leiden in general
The Leiden University Medical Center is the medical faculty of Leiden University and is abbreviated LUMC. The school work in Leiden was challenging. It was definitely not the case that you could take it a bit easier because you were on exchange. The workload is high at LUMC and there is more self-study assignments and workgroups than at Karolinska. Karolinska has more lectures and everything you need to know for the test is in the lectures. At LUMC, for many courses, you weren't in school for more than 3-4 hours, however, you were expected to read pages in the books and answer questions for the day after. The workload also starts abruptly, there is not really a slow first week where you get to know the course. Already the first day you will receive assignments for the day afterwards.
This being said, it is surely possible to keep up with the workload. It is very hard to save everything to the last minute. You won't have time to read all the necessary pages. If you consistently study throughout the term, you will have time over to do other things such as travel and social activities, but it's important to plan.
Many of the lectures take place in the actual hospital building. I really enjoyed that because it was nice tie between the theoretical and clinical aspects of Biomedicine. Many of the aspects are more clinical than Karolinska. We got clinical cases to examine for many of the workgroups and also got a patient demonstration during one of the courses. On the other hand, there is not as much practical labs at LUMC. There is only a few labs during the entire term and very few lab reports. Karolinska has a lot more lab practicals. Some of the lessons termed microscopic practicals actually are only on the computer, with microscopic images.
Teachers
For the most part, I have been very happy with the teachers at Leiden. Many of them were passionate about their subject and had good teaching skills. There were quite a few guest lectures who only taught a few lectures, but there were also some teachers who were in charge of the whole course and taught a large part of the lectures. Similar to Sweden, there is quite a flat structure when it comes to authority so it is possible to ask questions to teachers and discuss with them the courses. The workgroups are when you get the best contact with the teachers and can hopefully feel free to ask more extensively about the subjects.
Blackboard
Blackboard is LUMC's version of Ping Pong. It is an online resource which is used frequently by teachers and students. It is important to check it regularly. Usually if there is any change in schedule or if a teacher wants to contact the student, they write it here. Sometimes assignments are written on Blackboard or in the module book, but otherwise not mentioned so it's important to log in frequently. Blackboard is where you can find weblectures. The weblectures are recorded videos of old lectures including PowerPoint slides. They are a very helpful tool. You can pause them as much you want and even speed them up if you want to process them quicker. Going through the weblecture can help information stick which it didn't the first time you heard the lecture. It depends on what course you have, how long it takes for the weblectures to be uploaded.
TextbooksFor every course there are textbooks which are recommended to buy. It is definitely not necessary to buy all of them. The Immunology course is heavily based on one textbook (Parham) and I was very glad that I bought it. I read almost the entire book since you are supposed to read pages from it for each workgroup, usually around a chapter per work group. The Infectious Agents and Diseases course did not have an assigned textbook, instead you were given articles to read which could be attained online. The Physiology textbook had four textbooks which you were to read from for each self study assignment. I did not buy any of them since they were too expensive. Some students bought some of them which seemed more important. Some of them can also be used in other courses later on in the Biomedical program. Each course also has a module book which lays the groundwork for how the course is organised and also contains all the self-study and workgroup assignments. You can either choose to buy a paper copy or use the one they uploaded on Blackboard. You can buy the textbooks and module books through the LUMC bookstore. Since it is run by the students, the opening hours are very limited. It is only open certain weekdays during the week and usually during lunch hour.
Grading System
There is a different grading system at Leiden than at Karolinska. The grading system in Leiden goes from 1 to 10 with 1 being the worst and 10 the best. You need a 5.5 to pass a course. It is almost impossible to get a 9 or 10. The grades you get in Leiden won't be translated into Karolinska grades meaning it will just say that you have passed all the courses, not if you got a G or VG.
Tutor Lessons
LUMC has organised special tutor lessons for international pre-masters and exchange students. They are taught by a Master's student. The idea of the tutor lessons is for new students to get more used to how things are taught at LUMC. The lessons go over how best to tackle the exams and for the physiology course, the lessons summarized all the subjects we had learnt so far. They were especially helpful. Not all tutor lessons felt necessary to go to, but many of them were valuable.
Tests
The final tests were not as long as at Karolinska. None were longer than three hours. This meant that there could be quite a time pressure which we are not used to at Karolinska. Some of the tests also had a different structure than the standard final tests we usually take at Karolinska. The immunology test was an open book test. The physiology tests were multiple choice.
