In general, college-level courses are designed to be challenging. In fact, most people consider physics to be one of the most challenging courses you can take. One of the reasons physics is so difficult is that it involves a lot of mathematics. It's not difficult if you can rearrange the equations and you're good with mathematics.
They give you a giant leaf that you can take to the exam with LOTS of equations. Level A Physics is considered one of the most difficult courses due to the quantity and complexity of the material, as well as the difficulty of the exam questions. However, the subject is quite interesting and convincing for many of the students. Torque, rotational dynamics and moments of inertia are considered to be some of the most difficult subjects in physics 1, as they often require visualization in more than 2 dimensions and a higher level of understanding.
The difficult part is that physics is the first time that many students have to use their knowledge to solve problems rather than simply regurgitating facts. Level A Physics is one of the most difficult subjects at Level A due to a large curriculum, difficult concepts, laboratory components, and challenging exams with a lot of mathematics. Overall, Physics 1 is certainly a difficult course, but it's not very difficult if you study regularly and review consistently. Therefore, according to pass rates (more details here), Level A Physics is more difficult than the average Level A.
One might perceive biology as the most challenging topic, while another might consider physics as the most difficult A-level course. Physics 2 is certainly more difficult than Physics 1 because it is more abstract, has more irregular calculations and has more challenging subjects. However, once I decided that I wanted to learn physics, I worked hard, studied and discovered how to excel despite being so weak in the mathematics needed to specialize in it. In addition, it is sometimes difficult to find suitable online resources for physics courses, since the material is quite comprehensive and it is almost impossible to find a video or article online that explains every scenario that may arise.
Physics is very difficult because it is an abstract subject, it uses a lot of advanced mathematics and chemistry, it has challenging concepts that are difficult to visualize, it focuses on both the microscopic and macroscopic levels, and can often transcend reality.
