This guide breaks down each course, explains why it’s difficult, and helps you decide if it’s the right fit for you.
What Makes a Course “Hard”?
Before diving into the list, it’s important to define what “hard” actually means. A course is typically considered difficult if it involves:
- Heavy workload (long hours of study and assignments)
- Complex concepts (abstract or technical subjects)
- High competition or failure rates
- Practical demands (labs, clinical work, fieldwork)
- Long duration of study
So, in the course of this post, we shall be judging using the above mentioned features.
Top 20 Hardest Courses to Study
1. Medicine (MBBS/MBChB)
Medicine consistently ranks as the hardest course globally because it involves heavy workload. It is not just an exaggeration, it is a reality.

How to Succeed in Difficult Courses
If you choose one of these challenging paths, here’s how to succeed:
1. Develop Strong Study Habits
- Use active recall and spaced repetition
- Study consistently, not last-minute
2. Master Time Management
- Create a weekly study schedule. Making a timetable for yourself is a way to keep yourself in check, ensuring each task is done appropriately and at the right time.
