A physics degree requires approximately 120 credit hours, with a heavy math foundation (Calculus I-III, differential equations, linear algebra) and a core physics sequence covering classical mechanics, electromagnetism, thermodynamics and statistical mechanics, quantum mechanics, and modern physics — all with laboratory components. The program is one of the most mathematically demanding undergraduate degrees, and the transition from introductory to upper-level courses involves a significant increase in abstraction and difficulty.
You want to know if you are smart enough. The honest answer: physics is not about being smart in the way people typically mean. It is about being persistent with difficult, abstract problems and being comfortable with the feeling of not understanding something for hours or days before it clicks. The students who succeed in physics are not necessarily the ones who found high school easy — they are the ones who developed the habit of working through confusion rather than giving up.
The National Center for Education Statistics shows that physics is a smaller but respected degree category1. The graduates are highly sought across industries — not just for physics-specific roles but for the analytical and quantitative thinking the degree develops.
For career and salary analysis, see the physics degree overview. This page covers the specific requirements.
The single biggest predictor of success in a physics major is your comfort with math. If you are solid through Calculus II and enjoy the process of solving mathematical problems (not just getting answers), the physics program is likely a good fit. If math feels like an obstacle to endure rather than a tool to enjoy, the upper-level physics courses will be a sustained struggle because they are essentially applied mathematics.
Core Coursework: What Every Physics Major Takes
Mathematics (first two years):
- Calculus I, II, and III
- Differential Equations
- Linear Algebra
- Mathematical Methods for Physics (some programs) — complex analysis, Fourier series, and partial differential equations
Core physics sequence:
- Classical Mechanics — Newtonian mechanics using calculus, then Lagrangian and Hamiltonian formulations. Forces, energy, orbits, and oscillations.
- Electromagnetism — electric and magnetic fields, Maxwell's equations, electromagnetic waves, and circuits. Typically two semesters.
- Thermodynamics and Statistical Mechanics — heat, entropy, the laws of thermodynamics, and the statistical basis of macroscopic behavior.
- Quantum Mechanics — wave functions, the Schrodinger equation, quantum states, and measurement. The most conceptually challenging course.
- Modern Physics — special relativity, atomic structure, nuclear physics, and particle physics. Often taken as a bridge between introductory and advanced courses.
- Advanced Laboratory — sophisticated experiments in optics, electronics, nuclear physics, and data analysis. Writing formal lab reports.
- Senior Thesis or Capstone — independent research or comprehensive project.
BA vs BS
BS in Physics — the standard professional track with more math and physics requirements. Expected for graduate school and physics-related careers. BA in Physics — fewer requirements, more room for double majors or liberal arts breadth. Suitable for students combining physics with education, philosophy, or another field. BS in Applied Physics or Engineering Physics — emphasizes practical applications. More overlap with engineering coursework.
Common Concentrations
Astrophysics/astronomy — stars, galaxies, cosmology, and observational techniques. Condensed matter/materials — properties of solid-state materials. Connects to materials science and semiconductor industries. Biophysics — applying physics to biological systems. Bridge to medical physics and biomedical research. Computational physics — numerical methods and simulation. Combines physics with programming. Optics/photonics — light, lasers, and optical systems. Applied and research paths. Nuclear/particle physics — fundamental particles and forces. Primarily academic research.
The transition from introductory physics (General Physics I and II) to intermediate courses (Classical Mechanics using Lagrangians, Electromagnetism using Maxwell's equations) is the sharpest difficulty increase in the major. Introductory physics uses algebra and basic calculus. Intermediate physics uses multivariable calculus, differential equations, and vector calculus continuously. Students who coasted through the intro sequence based on intuition often hit a wall when the mathematical formalism becomes essential.
Prerequisites and Admission Requirements
No competitive admission beyond university admission. Math placement is the critical factor — start at Calculus I to stay on track. Physics courses and math courses run in parallel, and falling behind in either sequence delays the other.
Skills You'll Build (and What Employers Actually Value)
Quantitative problem-solving — approaching complex problems with mathematical tools. The most valued and transferable skill. Mathematical modeling — translating physical situations into mathematical descriptions and extracting predictions. Programming and computation — most programs include Python, MATLAB, or C++ for simulation and data analysis. Laboratory skills — experimental design, data collection, error analysis, and instrumentation. Abstract reasoning — working with concepts that are not directly observable (quantum states, fields, statistical ensembles). Transfers to software architecture and systems thinking.
The Bureau of Labor Statistics reports that physicist positions earn a median annual salary of $142,8502. However, most positions at this level require a PhD. Bachelor's-level physics graduates are competitive for data science, quantitative finance, software engineering, and engineering roles that value their mathematical and analytical training — often at salaries exceeding those of graduates with "matching" degrees because of the perceived rigor of physics training.
What Nobody Tells You About Physics Requirements
You will feel lost more often than you feel confident. This is normal and part of the process. Physics problems are designed to be hard enough that you cannot solve them immediately. The skill you are developing is the ability to work through confusion systematically.
Quantum mechanics changes how you think about reality. It is not just a hard course — it challenges fundamental assumptions about how the world works. Students who engage with the conceptual implications (not just the math) find it one of the most intellectually stimulating courses in any degree.
Research experience is expected, not optional. Physics graduate programs and many employers expect undergraduate research. Start looking for faculty research opportunities during your sophomore year.
Physics graduates rarely work as "physicists" with a bachelor's. Most bachelor's-level physics graduates work in engineering, data science, software development, finance, or teaching. The degree opens these doors because employers recognize the rigor of physics training.
Graduate school is free in physics. PhD programs in physics provide full tuition coverage plus stipends. If you are accepted to a PhD program, you should not be paying to attend.

FAQ
How hard is a physics degree?
Physics is consistently rated among the most difficult undergraduate majors. The combination of advanced mathematics, conceptual difficulty, and laboratory work creates a sustained challenge. The difficulty is not about memorization — it is about developing the ability to apply mathematical tools to physical problems and reason abstractly about systems you cannot directly observe.
What math does a physics degree require?
Calculus I through III, differential equations, and linear algebra are the minimum. Many programs also require mathematical methods courses covering complex analysis, Fourier series, and partial differential equations. The total math requirement is typically 18-24 credit hours. Physics is sometimes described as "applied mathematics with lab work."
Can I get a job with a bachelor's in physics?
Yes. Physics graduates work as data analysts, software developers, engineers, quantitative analysts, technical consultants, and research associates. The Bureau of Labor Statistics notes that the broad analytical skills of physics graduates make them competitive across many quantitative fields2. See the physics careers page for details.
Is physics harder than engineering?
Different types of difficulty. Physics is more abstract and mathematically theoretical. Engineering is more applied with more design projects and lab work. Physics requires deeper mathematical reasoning; engineering requires broader practical problem-solving. Both are rigorous, and the "harder" one depends on your strengths.
Do I need to be good at programming for physics?
Programming proficiency is increasingly essential. Most modern physics involves computation — simulations, data analysis, and numerical methods. Python and MATLAB are the most common languages in physics. While your program will introduce programming, developing genuine proficiency requires practice beyond what courses require.
Should I get a physics degree or an engineering degree?
Choose physics if you want to understand fundamental principles and are comfortable with abstract thinking. Choose engineering if you want to design and build things with clear practical applications. Physics is broader and more theoretical; engineering is more applied and career-focused. Physics graduates can work in engineering roles; engineering graduates rarely work in physics roles.
