Office Hours & Problem Sets

Hello Class,

I should have your final problem sets graded by Friday, so if you wish to pick them up to help with your studies, I plan on hosting office hours between 12:00 to 2:00 pm on Friday at the Financial Markets Center. I may also be available after 5:00 that day, if you wish to ask questions or pick up your problem sets then you should email me beforehand. Provided you study problem sets 3 & 4 as well as the practice midterm, you should be well prepared for the exam, which is structured in the same manner.

However, if you do not understand how to apply the concepts learned in class, nor how to utilize derivatives or standard normal distributions, this and other exams will prove quite difficult. I recommend at a minimum using a graphing calculator such as  TI-84, TI-89, or TI-Nspire CAS, but it is not necessary, albeit very helpful. Furthermore, DO NOT round any intermediate calculations, otherwise you may get the wrong answer.

There have been times when the precision level of the final answer results in very difficult outcomes if the intermediate calculations are rounded. Additionally, show all relevant work, or you may not receive partial credit. Answers that are close but mechanically wrong are still incorrect, but answers that are close due to rounding error may receive credit depending on the severity. Make sure you always answer the question asked, not tangential information.

I believe that each of you are capable of performing well in the class, as long as you do the appropriate practice and check your work carefully. Many of you have performed exceptionally on the problem sets so far, but some of you likely will need to dedicate significant time to really understand the material. Furthermore, even if you did well on the problem sets, you should still study them to ensure you have not forgot the material. Good luck!

Q3 & PS2

Hello Class,

Overall, very well on the Problem Set with almost 70% of the class achieving a perfect score. While almost everyone missed at least one question on the quiz, the majority of the class scored 80% or higher. It appears that some of you may need to brush up on your statistics, and it is always prudent to thoroughly check your work to make sure you answer the question asked. Also, always be sure to carefully read the assigned readings in order to perform optimally on the quiz, as there may be some nuances where certain concepts sound similar but are distinctly different.

Thank you for your time and considerations.

Sincerely,

Alexander Law

 

Problem Set 1

Hello Class,

Overall, well done on the problem set. The majority of you have a very firm grasp of the subject. For those of you that struggled, I would once again suggest studying how to take derivatives and the implications of derivatives very carefully should you wish to do well in the course. Additionally, even if you know the material well, be sure to carefully check your work for any intermediate calculation errors, or for incorrectly reading the question and hence not appropriately answering the question.

Best Wishes,

Alexander

Calculus

Hello Class,

Overall, a significant proportion of you did very well on the first quiz. As a rule of thumb, be sure to show all work on your homework and test assignments, as you cannot receive partial credit without clear steps demonstrating your thought process.

There are a few of you that struggled with the computation portion of the quiz. This may indicate that you may not be familiar with some of the Calculus concepts necessary for the course, and that you need to practice taking derivatives and understand their significance.

Additionally, be sure to thoroughly check your work to identify any possible transcription errors, intermediate calculation errors, and errors in answering what the question asked for. When asked to take the second derivative some of you solved for the first derivative.

Occasionally, there may be extra credit opportunities offered by Dr. Garven that will allow you to replace a low quiz grade. Even if you are doing well in the class, it would be prudent to take advantage of these opportunities should you struggle on a future assignment.

Finally, be sure to always turn in your assignments when they are due. Even if you are present in class, if you do not turn in your quiz or homework that day, you cannot receive credit because the answers for quizzes are discussed in class and the answers to the problem sets are posted after class.

Thank you for your time and considerations.

Sincerely,

Alexander Law

How to Succeed in 4335

Dear Students of Dr. Garven,

My name is Alexander Law, and I will be your Graduate Assistant for the course(s) you are taking with Dr. Garven. I just wanted to briefly go over some guidelines of what to expect for the class, and how to succeed in the course.

First, keep in mind that there will be quizzes at the beginning of class, whenever there are assigned readings for that day. Do also note that your homework assignments are due at the beginning of the class, and because the answer key is posted online after class, NO late work is accepted. Turning in an incomplete assignment is still better than getting a zero.

The first two homework assignments and weeks of class involve going over some of the basic math and statistics concepts you will need to do well in the course. You should expect to having a basic understanding of Calculus, particular deriving equations to solve for a maximum, as well as the standard normal distribution.

There will be three exams in the course, two midterms and a final, and approximately 10 problem sets. Since the first two problem sets are based upon your math and stats review, you should expect approx. 2-3 problem sets of content per exam. The Final can replace a low grade on a midterm, but if you are actively engaged in class and take care to study the problem sets diligently, you should be able to perform adequately on all three exams. The two midterms typically include at least 3 required problems consisting of 3-6 subsections per problem, and partial credit can awarded for each subset of the question.

Thank you for your time and considerations.

Sincerely,

Alexander Law
