TIA Practice App (iOS / Android)

June 28th, 2019

I am very excited to announce that the Practice app is now available on both iOS and Android.

Now you can practice problems wherever you are without any need for a live internet connection, and your problem history will stay synced across all of your devices.

Here are some of the features in v1:

  • Work problems in order or randomly in continuous mode
  • Create custom length quizzes to emulate timed practice exams
  • Get instant feedback on problem attempts, with both written and video solutions
  • Filter problem sets by flagged, missed, or SOA
  • Review problem history and re-work problems directly from history
  • Quick access to the discussion forum for each problem

What I am most excited about is the future of this new app.  This is a platform that we can use to add more and more features over time.

Let me know what you think of the app, and what features you would most like to see added!

Don’t forget that you can also download lessons using our Learn app (iOSAndroid), and review formulas and concepts using the flashcards in our Review app (iOSAndroid).

2018 Syllabus Changes

June 28th, 2018

The SOA has made changes to all of their preliminary effective for the later sittings in 2018. The Exam P syllabus has changed the least, with one new topic being added starting with the September 2018 sitting. This new topic is probability generating functions, and is now covered in a new lesson B.2.6. If you are taking the exam in July of 2018, you can skip this (and likewise skip the problems in the problem system labeled as not being on the July 2018 syllabus). If you are taking the exam in September, 2018 or later and have completed Chapter B.2., you should go back and watch this lesson at some point. It is not urgent to do so, as it is independent of all of the later material and will not be a heavily tested topic.

Practice Exam Strategy

March 1st, 2016

If you are taking the exam later this month, it is time to start taking practice exams. When you do that, you want to be sure that you are reviewing them carefully and learning from your mistakes. The reviewing process is both the most important part of a practice exam, and the one that people are most likely to overlook.

I’ve posted a video that talks about this, but the TLDW version is that the way that I would approach a practice exam is to spend 2, 3, or maybe even 4 days on it. I would take it one day, under strict exam conditions with no formula sheets, and find out what my raw score is. On day 2, I would redo the problems I missed with my formula sheet to see if I had any new ideas or if any formulas would help (if they would, then that is a formula I need to memorize!) Then I would review the solutions to all the questions I missed, as well as any questions that I got right but found hard.

Now comes the part that people skip: On day 3, I would redo all of the questions that I missed to help solidify the ideas I learned from the solutions. Passively watching a solution won’t help you remember something as well as redoing it, and this will give you your biggest improvement. If you can score 85% on the easiest 80% of the material, and guess on the rest, then you should pass, so you really need to learn from your mistakes and solidify that easy 80%.

Ok, but I said 4 days isn’t unreasonable. How does this stretch out that long? Maybe in doing these practice exams you find yourself missing multiple questions on core topics, such as normal approximations or computing moments or things about Poisson distributions. If so, then redoing a bunch of practice problems on those specific topics can really help. Only do this with the most commonly tested topics — if you miss a question on Chebyshev’s inequality or some other really obscure thing, then this close to the actual exam the best strategy is to not care very much. That will be part of the 20% that you can guess on, and you certainly don’t want to waste a lot of precious, last minute time cramming in material that probably won’t be on the exam.

Exam Aftermath

January 28th, 2016
Now that the January sitting has ended, I want to think about what to do next. If you passed, then congratulations! But now that means moving on to the next exam. P and FM should be your first two preliminary exams as they are easiest, then MFE is next easiest. So if you haven’t yet taken FM, you should tackle that next, while if you have, you should move on to MFE.
But what if you got bad news? The first thing to do is to think about why you failed. I often ask people whether or not they ran out of time — those who did often need improvements in many areas and need to work lots of practice problems. Those who didn’t are more likely to have specific areas of weakness that need practice and improvement. So if you are in that situation, you want to figure out what those weak areas are.
You now get a partial score breakdown of how you did on the different areas of the syllabus, which they label as General Probability, Univariate Probability, and Multivariate. In terms of the seminar material, general probability corresponds roughly to A.1, A.2, and lesson A.4.1, while univariate is A.3, the rest of A.4-A.6, and all of Section B, and multivariate is section C. Unfortunately, even If you score ‘low’ on one area but not the other two, then you only have a vague description of your troubles and need to refine it a bit. To do this, you can work some sample exams or look at your old practice problem scores and see if there are lessons that leap out as needing improvement. The best situation is to be able to narrow it down to a few very specific topics, such as struggling with combinatorics, or conditional moments, or normal approximations. Then between now and your next exam, you want to work a lot of problems on those areas and try to improve on them the most. Just don’t forget to also occasionally work other review problems on general topics as well, and also make sure to redo the practice exams at some point.
One final thing you should do now while the exam is still relatively fresh is to write down what you remember of the questions you struggled with on the exam. You can come back to those notes closer to the exam date to remind you of some things to focus on, plus writing those down may help you figure out what some of your problem areas are.
Whatever your result was, good luck on your next exam.

Updating handouts — what’s new?

December 7th, 2015

I am in the process of uploading new versions of all of the chapter handouts, but for the most part, you don’t need to redownload much if you don’t want to. What is truly new is the following:

  • More problems have been added to A.7, B.6, and C.6. The SOA has recently expanded their published sample problems, and I’ve added the new ones to these 3 chapters.
  • For all chapters, the handouts .zip file now contains a new file called whatever_solutions_combined.pdf, which is a file that contains both the problems and solutions side by side to make it easier to read on-screen. This file is probably too prohibitively long to print.

I haven’t yet recorded new video solutions for the new SOA problems. Those will be coming later on.

Sunsetting old seminar

August 23rd, 2012

As everyone should now be using the new (2012) version of the 1/P seminar, I will be removing the previous version from the lessons tab on  Sept. 3rd. If you are still using the original version of the seminar, look at the videos on how to change over to the new version.

Edit: The conversion is done, and only the new version of the seminar is available.

TIA Discussion Forums

July 6th, 2012
We are very excited to announce the launch of the TIA forum!
In the past, using TIA to study for exams has been a relatively solitary endeavor.  You watched the videos, worked the problems, and occasionally emailed your instructor for assistance.  If you prefer to learn that way, then don’t worry, you can still do it that way.  Think of the forum as an additional (and optional) way to enhance your learning.  You might just browse other student’s questions, and decide to give it a try later on.
Although a few TIA members have gone out of their way to interact with others by posting on the Actuarial Outpost or other public forums, the TIA forum makes it incredibly easy for all of us to interact with other members.  Any time you have a question or a topic for discussion, you can immediately enter the subject forum and make your post.  Everyone else that is subscribed to the seminar will see that there is a new post in that subject forum, and can respond immediately, seconding or answering your topic.  Watch the short video posted in the “Before you begin” section of the course to see how the forum works.
Making your experience at TIA more interactive will result in much more powerful and effective learning.  But another terrific aspect of the forum is that it will act as a growing and changing knowledge base of answered questions.  As your instructor, I’ve found that I answer the same question by email many times.  The forum will allow me to post answers to questions in a way that will remain readily available to all seminar users.  After a while, you’ll find answers to many of your questions instantly in the forum, instead of needing an email response.
But the forums aren’t just for my answers to questions.  As you probably know, there is no better way to test your knowledge than to try to answer the questions that other learners ask.  You should try to answer the questions that other members post as often as you can.  Other members can chime in to ask more about your answer too, and I’ll be keeping an eye on things to make sure that all the questions receive accurate and useful responses.
As always, we want your learning experience here at TIA to be a positive one.  When interacting with each other on the web, please be sure to maintain a cheerful attitude and encourage your fellow learners.  Feel free to immediately flag any post that you feel would discourage anyone from interacting.
The forum is open now, so go ahead and watch the introduction video and get started!  You could start by introducing yourself in the “Before you begin” subject forum.

2012 Errata

May 16th, 2012

I’ve fixed 6 errors in the 2012 problems/solutions. The handouts are updated, but if you don’t want to re-download them, here are the changes:

A.1 # 15: in the example realizing the minimum, P[A'B'] should be 0, not 0.1.

A.2 # 5: P[D] = 0.274, not 0.247. I used 0.274 in the following calculations, so nothing else is affected.

A.3 #13 and #14: the exponent in the numerator should be inside the [ ].

A.4 Solution to #31, the (1/2)^2 in the denominator should be (1/2)^3

B.1 # 15 I took the wrong square root: y>a, so we want E.

B.6 # 20 theta=8.5, but the problem asks for E[X], which is 2*theta/3 = 5.7

Video solutions to B.1#15 and B.6 #20 aren’t yet updated.

CBT sample exams

July 10th, 2010

We have added a CBT format to the sample exams. This means that you now have the choice of printing out the practice exams and taking them as a traditional paper and pencil exam, or you can take it on your computer in a format that is very similar to what you will see on the exam day. There are a few differences between our CBT version and the SOA’s version, but we think it is close enough that it will be good practice. In particular, you can get used to using the online exam tables.

For a demo of how to use the sample exams, we have a sample videos that you can watch in either QuickTime or WMP format. When you take a CBT sample exam, the exam will end whenever time runs out or if you click the “End” button on the review screen. At that point, your exam will be automatically scored. Note that closing the exam window will exit the exam without saving your progress or grading anything.

One feature that you should experiment with is the ability to mark questions for review. At any point during the exam, you can click the “Review” button on the bottom of the screen and that will give you the option to review either all of the exam problems, only those problems that you have marked for review, or only those problems that you haven’t answered. For example, one possible exam strategy is to make a first pass through the exam working all of the problems that you can do quickly, marking problems that you think you can do but will take a long time, and skipping problems that you don’t know how to do. Then when you are done with your first pass, you can select “Review Marked” and do the longer problems that you know how to do. After finishing that, you can review the unanswered problems that you didn’t initially know how to do and either guess or take a second stab at them.

As the CBT format is a new feature, we welcome any comments and suggestions that you may have for it. In particular, if you have taken the official exam and can let us know about some format changes that we need to make we would really appreciate it. There will always be some differences since we have to deal with different browsers and screen sizes, but we would like to minimize them. Known differences are:

  • On the official CBT exam, if the problem is long enough that you need to scroll down to see all of the answer choices, you must scroll down before selecting your answer. We do not force you to do so.
  • The sample CBT exam on www.beanactuary.com has the exam tables in a different order than the table on the SOA webpage. We are currently using the SOA webpage’s order, but are not sure which way you will see it.
