Well it’s been 3 years and I’m halfway through the Maths degree I started “for fun” because I needed some mental stimulation that I just wasn’t getting in my work at the time. 3 companies later and I’ve got the challenge I was craving, and since the results of the last two modules are now out, it seems like a good time to review my experiences with the OU. Continue reading OU Maths – halfway review
Last week I took the exam for the level 2 Open University module M208 (Pure Mathematics). Just like last year with MS221, I’d not studied as much as I wanted, and had given myself two clear days before the exam to “cram” as much as possible and hope for the best. I want to make it very clear that this is a really poor strategy for any student wanting to revise and please with you not to copy this method! Continue reading M208 – revising in 2 days
It’s probably not a huge surprise that with a lowering of tweets and posts on this blog that I’ve been pretty busy. Today I got the results back from my second rushed TMA and I’m disappointed, but I’ve nobody to blame but myself.
The OU is pretty clear that you should study about 16 hours a week for a 60 point module and about 8 for a 30 point module. As I’m doing M208 (60 points) and DB123 (30 points) this means 24 hours of study alongside a (very) full time job. Given my love for maths and the ease with which I do pick it up, I got away with less than half the recommended time and still got distinctions for the level 1 modules I’ve done so far. Continue reading Rushed TMA – not my finest hour
The new OU term started on the 3rd October, but I’ve been working on M208 for four weeks now (although am yet to really do much other than skim through the introduction for DB123). I had a grand plan of confining my studies to the time I spent commuting by train and tutorials as I knew that I would have very little time outside of these short windows to dedicate. So how have the past 4 weeks gone? Continue reading Studying by train
After yesterday’s Girls can code the BBC kicked it up a notch with the Gamechangers – a TV movie about Rockstar Games and the controversy around GTA San Andreas. At the start, it was made clear that Rockstar weren’t involved and that it had been pieced together from court reports and third party interviews. If you missed it then it’s available on iPlayer for the next month. Continue reading The Gamechangers – BBC Make it Digital Season
At the weekend I signed up for my next maths modules with the Open University. I’ve got three distinctions in the level 1 modules and, aside from my severe annoyance with being forced to do a level 1 module I’m not interested in as “punishment” for skipping the easy start module1, I was desperate to do the next module. However, I dragged my heels this time. Continue reading Studying Maths – decisions on level 2
So the results are starting to come out for the OU exams taken in June. Those who were on their last module have got their final degree classification and for the rest of us we’re getting our individual module scores. Despite not being due for another 8 days, the results for MS221 came out today.
If you’ve been following my blog you’ll know that I really hadn’t focused on studying for this module as much as I should and, with a new role taking up my time in the evenings and weekends I just hadn’t revised as much as I should have done. I even took my text books to the ReWork DL conference in Boston but only opened them briefly on the plane on the return flight. So how did I do?
So, a few days ago I tweeted that I had this snippet from World of Warcraft going round my head where Illidan taunted that we weren’t prepared for what awaited us. It was how I felt going into MS2211 and now that I’ve done the exam I wanted to reflect on why I’d ended up feeling unprepared for a test in a subject I am very enthusiastic about for a degree I’m doing for no direct gain other than for the fun of learning.
I started this degree back in 2013 because I was intellectually unstimulated in my job. I was busy, spinning many plates and wasn’t bored, but there just wasn’t anything to do that really set my neurons firing. I’d started the process of looking for another job for a whole host of reasons I won’t go into, but I could feel my brain getting “comfortable” at not having to think much beyond which of my team needed to do which task in what order in response to changing priorities. So I signed up to do the maths degree I’d always wished I’d done. Continue reading MS221 – was Illidan right?
So – I’m approaching the end of my third OU module, MS2211, and the exam is in a few days. I missed all the local revision tutorials through being away with work2 and, despite some good intentions, I am woefully behind. Consider this a crammer’s guide for learning university level mathematics in 3 and a half days 😉3.
MS221 consists of four blocks: block A covering sequences, conics and geometry; block B covering iteration and matrices; block C covering more complex4 integration and differentiation and Taylor Polynomials; and block D covering complex numbers, number theory, groups and logic and reasoning5. The exam allows an annotated handbook and so it is fairly easy to prepare given a few days of dedicated effort, which (if you’re reading this in time, may help6. Continue reading Preparation for MS221
In my last post I talked a little about logic as it applies to generic statements. Now it’s time to think about more mathematics proofs and different techniques. As part of MS221 there are two proof types that we need to consider: proof by exhaustion and proof by induction. This all lays the foundations for building more and more complex mathematical statements so it’s important to get the basics right.
Firstly, proof by exhaustion. This simply means that we try every possible valid input and check that the result is true. A single false result would disprove our proposition. So let’s consider an example: Continue reading Proof by Induction
