It’s practically my first real exam.  I could count my CompTIA A+ certification (1995?) and my Knowledge of Life and Language in the UK (2014, I think) exams, but they were each considerably quicker than an hour.  My Graduation Equivalency Diploma in 1996 definitely counts, though.  It was a three hour exam taken at the community college I dropped out of, so … Awkward.

Subsequent to my last post about MST-124 revision, I’ve gone through every unit of the module completing practice workbooks offered on the module.  I had intentionally saved these for revision, but forgot about them until just after my last post.  It took about three weeks to get through them, but it paid off.  My performance on past papers went up nearly 10%, and I now feel like I’ve got a real shot at a distinction, if I can keep my brain fresh for just one more week.

Next Tuesday is the exam.  I panicked today and bought new pencils to keep in my car.  And cough sweets/drops because … Look, I already said I panicked.

What I’d like to do from now until then is just do every past exam paper over and over.  I’m not remembering the exact answers, and the questions are all so similar (at least for the 2-mark Section A questions 1 through 32) that they all blur together, which may be further helpful in the exam.  They take just under 2 hours each, though, so the commitment is not insignificant, and I only have time after the little ones’ bedtime.

At some point I’m going to properly review MST124 and TM129, but I don’t know if I’ll get it done before or after results day, which is mid-July.  I should probably do it sooner rather than later, because my opinion of TM129 appears to be plummeting the more time passes.

My revision plan has been … untenable.  I had hoped to start with a practice of the entire exam, find my weak spots and get a sense of time, and slowly work away at those, then do another full practice of the entire exam maybe a week before the actual exam time.  I liked this plan because the weak spots identified this way would be exactly the types of questions to show up in the exam, as the exam questions seem to (mostly) follow similar types of question year after year.  The practice exam before the real exam would hopefully work as a confidence builder going in, or at least a road map of where to start cramming in the last week.

Unfortunately, this plan requires two uninterrupted blocks of three hours several weeks apart.  I can’t seem to get any block of time that large while working full time, caring for little ones, and other responsibilities.  I’ve been so good with time management for studying over the last two years that it’s completely escaped my attention that I normally handle small day-to-day home life responsibilities a few times an hour between blocks of concentration.

So instead, I’ve been revising … everything.  All twelve units.  I got through the last one a couple of nights ago.  I’ve been tracking my progress using MST-124’s Revision Quiz.  This is a quiz with just 12 questions, one random one from each unit.  I’d have thought that this structure would make it very uneven for a battery quiz, but it proved to be quite effective.  No matter how many times I took it prior to revising, it took me one hour (with a variance of 7 minutes).

After three weeks of revision, it’s down to under 25 minutes.  I’m pretty sure that’s as fast as I’ll be able to get, so the rest of revision will be all about accuracy.  It’s a shame my revision time is nearly half up already.  Most students are starting their revision period today, though (as our final TMA was due last night), so I’ve given myself a large advantage.

More good news comes in the form of realising how much I actually have to remember.  A pass is 40% and the exam is made up of multiple-choice questions with five possible answers each.  If x is the percentage of the exam I can remember from revision, then assuming I get 1/5 of the remaining answers correct from the things I don’t remember, then in order to pass, I need

x + 0.2(100 – x) ≥ 40
+ 20 – 0.2x ≥ 40
0.8x ≥ 20
≥ 25.

So if I remember 25% of the material covered by the exam, and I get 1/5 of the remaining 75% (or 15% of the total) questions due to probability, that should combine to see me through to the 40% needed to pass.  Although making assumptions based on probability isn’t wise, at least I know my basic algebra is sufficient.

I’m done with the OCAS portion of MST-124!  That means that all my assignments are submitted, and the only the left is my certain doom the exam.  Thanks to the bewildering array of rules which make up the OU’s assignment substitution policy, I didn’t really have to submit my last assignment, TMA04, and would still have achieved a distinction level on the OCAS portion of the module.

It’s in, though, and I’m done!

Oh, wait, no.  There’s still that doom exam I mentioned.  Erm.  Imma talk more about the TMA.

The last TMA was by far the most difficult.  At least two, and maybe three questions aren’t directly referenced by the module materials at all.  And one other question is quite possibly a trick question.  I found three distinct and justifiable answers to it, so we’ll see how the one I picked goes.  (I liked maths because there wasn’t a subjective nature to the answers.  What are you doing to me?)

There’s one sub-part to a question which … Goodness.  It looked darned near unsolvable.  In fact, I thought it literally was for a few moments hours, because the modules basically only state that this type of thing exists, and doesn’t describe it at all.  Other websites also didn’t go into very much detail about the topic, so for once that didn’t help at all.  After trying very, very hard to crack the nut, I randomly selected the right nutcracker and found that … well, it was really all very simple all along.  (Except that it specifically asks you to do it in a way that makes it look impossible.)

I tried to make that last paragraph more vague, and I think I just about got it perfect.

So … Guh.  Revision.  I have a plan.  I’ve glanced at enough past exams papers to note that the majority of questions come from a set of very specific types of questions.  If I only revise those types of questions, I’ll probably come out with a Pass 2.  I’m starting to think a Pass 1 will be impossible due to how slow I am, and not all questions are from that specific set.  But we’ll see how it goes.  I’ve managed to give myself two extra weeks of revision time by finishing the study materials early.


2018/05/17 Edit: The mark on TMA04 for MST124 was the same as all others: 100.  I really would have liked some kind of feedback on my TMAs, and really only got tick marks on the answers.  I’m sure there were different approaches I could have used which could have been faster, or easier to remember, or in some other way preferred.  At least I can say I’ve been happy with my effort level all year long.  My practice exams are all coming within 3% of a distinction, so I’m really going to have to get that up about 10% to be confident under exam conditions.  I’ve got two and a half weeks, so here’s hoping!
