This has always been a thing.
I went to a scots uni in 1990 and you were able to direct entry into year 2 if you had very good a’level grades.
For me, year 1 was essential for many reasons. The main one was I’d never been taught to study effectively. How to structure essays and write ups, exam technique, time management, stupid stuff like that. The second was a’levels had all seemed fairly abstract to me, while year 1 was still physics, chemistry and biology, the way it was taught made me see the point, iyswim. Thirdly I didn’t have a career path in mind, or even a subject, so the way scots courses are structured really helped. Lastly as the first person in my family to go to uni, i needed that year just to figure out the basics.
The first year also gives you an idea of the lectures, departments, and the subject itself. Second year you pick 3 courses, so microbiology, medicinal chemistry, botany, zoology, biochemistry, physiology, anatomy etc. I had dismissed biochemistry as a course until I sat in on a lecture as a friend was going and I cba to go home for the hour, and realised it was what i’d been looking for, so I switched to biochem at the end of second year.
