**Statistical Inference**Sampling and parameter estimation, tests of hypotheses, correlation, regression, analysis of variance, sequential analysis, rank order statistics. Pre: Advanced Probability or consent.

**General Physics II Lab**Lab with electricity and magnetism and geometric optics. Pre: General Physics I and Lab, and Calculus II.

**Senior Seminar**Seminar for senior mathematics majors, including an introduction to methods of research. Significant portion of class time is dedicated to the instruction and critique of oral presentations. All students must give the equivalent of three presentations.

Right now, I am deciding which one of these four classes will be my last math elective:

**General Physics III**Relativity, introduction to quantum mechanics, atomic and nuclear physics, and physical optics. Pre: General Physics II and Calculus III.

**Combinatorial Mathematics**Finite configurations. Topics may include counting methods, generating functions, graph theory, map coloring, block design, network flows, analysis of discrete algorithms. Pre: Elementary Linear Algebra or consent.

**Introduction to Abstract Algebra**Introduction to basic algebraic structures. Groups, finite groups, abelian groups, rings, integral domains, fields, factorization, polynomial rings, field extensions, quotient fields. Emphasis on writing instruction. Pre: Linear Algebra and Proof-writing; or consent.

**Introduction to the Theory of Numbers**Congruences, quadratic residues, arithmetic functions, distribution of primes. Emphasis is on teaching theory and writing, not on computation. Pre: Proof-writing.

I'm kind of leaning towards General Physics III and Combinatorics, mostly because they don't seem to involve proof-writing. The other two classes are on there mostly because they fit nicely enough within my school schedule to allow me to work the maximum hours at my job. Anyway, in my General Physics II class I took last year, I kind of got lost trying to learn about light, reflection, refraction and the like, so I think I would have kind of a rough start at the beginning the General Physics III course. As for the senior seminar, I'm a bit hesitant on taking it with a certain professor, since he's teaching one of the classes I am taking right now. I'm not getting so good a grade in his class. On my last midterm, I am very sure that I got between a seventy and an eighty-percent, possibly even lower; and my homework scores average to a B-. So I'm a bit afraid of how he will judge my performance in the seminar.
