Difference in 3rd/4th Year Undergrad Physics

[Dgray101]

I am in my Second year of physics right now and I am just curious what the major changes from the first 2 years of math and physics take place in the third and fourth years. What should I expect? How can I prepare for these years and do well?

That depends on the school. My university scheduled the 2nd and 3rd year physics courses so you could "double up" on them, and complete the first three years of the major in two. I chose this option, so my first two years covered the standard undergraduate courses, and my last two years were full of special topics and graduate courses.

The point is, you should tell us what topics you have completed, and which ones you will take in the next two years. Then we can tell you what you need to brush up on to do well.

My first two years were challenging but not hard to manage, and I could easily juggle 16-18 credits (18 is the max at my school before you have to start paying extra). Now I'm at 16 credits with my first round of 300-levels, and attempting to self-teach intro chemistry for credit. I'm drowning in work and sometimes feel as though I don't understand key concepts. I'm still doing reasonably well in classes, but for me personally I've never gotten a B+ in anything and don't want to start this semester.

My advice would be to brush up on all the math and physics you've learned during the summer between sophomore and junior years. You're going to need all those concepts to come back quickly, otherwise you could be stuck on homework for hours. Also if grades as well as fully understanding your classes is a big priority for you, take less classes as you'll be able to devote more quality time to the important ones.

What classes (and textbooks) are you taking now, and what will you be taking next year?

I can tell you that the third and fourth years of undergraduate physics are significantly different from the first two years. In the first two years, you have likely focused on building a strong foundation in basic physics concepts and mathematical skills. However, in the third and fourth years, you will delve deeper into more advanced topics and develop a more specialized understanding of physics.

One major difference you will notice is the shift from theoretical concepts to more practical applications. In the first two years, you may have focused on solving textbook problems and understanding abstract theories. In the third and fourth years, you will likely have the opportunity to apply these theories to real-world problems and conduct experiments to test them.

Another difference is the level of mathematical rigor. In the first two years, you may have used basic calculus and algebra to solve problems. In the third and fourth years, you will likely encounter more complex mathematical techniques such as differential equations, vector calculus, and linear algebra. It is important to continue practicing and honing your mathematical skills in preparation for these advanced courses.

To prepare for the third and fourth years of undergraduate physics, I recommend staying on top of your coursework and maintaining a strong understanding of the fundamental concepts. It is also helpful to read ahead and familiarize yourself with the topics that will be covered in your upcoming courses. Additionally, seeking out research opportunities or internships in a physics-related field can provide valuable hands-on experience and help you apply your knowledge in a practical setting.

In order to do well in your third and fourth years, it is important to stay organized and manage your time effectively. These courses may require more independent study and research, so staying motivated and disciplined is key. Don't be afraid to ask questions and seek help from your professors or peers when needed.

Overall, the third and fourth years of undergraduate physics are an exciting and challenging time where you will deepen your understanding of the subject and develop important skills for a future career in science. By staying focused, organized, and motivated, you can successfully navigate these years and excel in your studies.
