  • Question about Dr. Broverman's weekly practice problems

    Dr. Broverman,

    I have already finished your Actex study Manual for P exam, and also I've already finished all 5 practice exam in the study manual. I don't really have any big problem with that ( my score is about 20-23 out of 30). Recently, I start doing your weekly practice problems, and I found that some of those questions are very difficult for me (maybe just difficult for me only, I don't know!! ), and it really discourages me by those questions.

    Please tell me the P exam in Feb will be that difficult??? Or do you all think I haven't prepared enough?? Please give me some advise!!

    All of your advise will be very helpful for me, Thank you very much

    Tears stream down your face
    I promise you I will learn from my mistakes

    The questions that I am posting are designed to be
    to be more challenging than exam questions are likely to
    be. I don't intend for them to be discouraging, but rather
    to provide a little more depth in some of the topics that
    are covered on the exam. The questions on the ACTEX
    practice exams are either from previous actual exams
    or are designed to be at the level of difficulty of the exam.
    Although it is not publicly announced how many correct
    answers are needed to pass, 20 to 23 out of 30 would likely
    be a pass.

      Dr. Broverman,

      I had a question about your ACTEX study guide. Chapter 8, Example 8-21, the very last line, you have:

      P[X+Y<=1] = ~~ ...... dx dy

      You integrate the inside and then have = ~ .... dx ???

      Did you switch the dx and dy? I am very confused.

      Thank you,

      Pete

        Pete,

        It looks like I mixed up my variables.
        The inside integration with dx should be
        integral from y (lower limit) to 1-y (upper limit).
        Then, the expression just to the left of 1/6
        should be the integral with respect to y from 0 to .5
        of 2/3 (1-2y) dy . Thanks for pointing that.

          Slughorn,

          That's an odd group of questions in the file.
          I will see what I can do with them.

            To Prof SAM

            This is to "publicly" apologize for bugging you, ever since i got into this site... Don't worry Prof, you won't be receiving any equations and problem sets from me.

            Good luck in your career.
            God bless you and your loved ones.

              Slughorn,

              No apology is necessary. One of the benefits of this is
              site is that it allows students to ask questions with the
              hope that they will be answered. It is natural to ask
              questions of an actuarial science prof who spends much
              of his time teaching this material. You shouldn't feel restricted
              in asking questions on this site, and I will continue to
              try to answer questions.
