Course Notes

We are using Nickolas Andersen's lecture notes: MATH 131A: REAL ANALYSIS

Homework

Solving problems on your own is one of the most important parts of this course. It will teach you how to apply your new knowledge and also be the best preparation for the midterms and final exam.

I encourage you to discuss the problems in teams but write up the solutions on your own. Simply copying your homework will not prepare you for the exams at all and is also not allowed (i.e. considered academic misconduct/cheating).

Every week you will be able to find a list of problems in the lecture schedule. They will be covering the material of the lectures and similar to exam questions.

You will have to solve these problems and hand them in at the beginning of the lecture every Friday. Your homework has to be submitted in a form obeying the following rules:

We will not accept your homework if it violates any of the above rules.

Exams

There will be two midterms and a final exam. Apart from the exceptions mentioned below, only writing equipment will be allowed in exams. Exams must be written in pen.

Cheatsheets: For each exam, students may bring a cheat sheet. Each student must prepare their own handwritten cheat sheet. For the midterms, the cheat sheet may consist of one side of half a standard (A4 or letter) sheet of paper (i.e. A5 or letter folded in half lengthways). For the final, the cheat sheet may consist of one side of a standard sheet of paper. Cheatsheets that do not meet these requirements will be confiscated at the beginning of the exam.

Calculators: You may use a non-programmable, non-graphing calculator in exams. Calculators not meeting this specification will be confiscated.

Study: Here I will post some practice exams which might aid your study.

Grading

The midterm scores will be adjusted to account for any difference in difficulty. Your final grade will be calculated using the maximum of the following two grading schemes. Your letter grade will then be determined by your rank in the class. Unless something very out of the ordinary occurs I expect to give approximately 20-30% A’s and 55-65% A’s and B’s combined.

Option 1:

10% (7 best homework scores) +
40% (combined midterm scores) +
50% (final exam score)
= raw final grade

Option 2:

10% (7 best homework scores) +
30% (best midterm score) +
60% (final exam score)
= raw final grade

Effectively, this will mean that unless you score worse in the final than both midterms, your lowest midterm score will be dropped. This also means missing one midterm probably will not impact your grade in any serious way.

Questions and Help

You can visit me and the TAs in our office hours.

Administrative questions should in the first instance be directed to your TA. If your TA cannot resolve your query then you should contact me.

If you need to email me, the subject line must include the string math131a. If not, then there is a good chance your email will slip through the cracks and remain unanswered.
