Seven years ago I was in work bored and desperate for a new challenge. My daughter had recently been born and I had decided to stop playing World of Warcraft. Needing a new challenge, I had toyed with an MBA but really wanted to do something for me. So I signed up for a BSc in Mathematics with the Open University, which I knew would take about 6 years part time while working. This week, I got the results for my final module and it was confirmed I had earned a first class honours degree. But why didn’t I do maths the first time round?

I’ve always loved maths. It just made sense to me. At junior school we had cards to work through at our own pace and I couldn’t get through them fast enough. By the time I started senior school I was about 3 years ahead and then had the shock of no longer being able to go at my own pace and having to redo a lot of the same work. It was frustrating. With a lot of effort, we manage to convince the school to let me take my maths exam 2 years early. The teachers made it clear that I would be left on my own to prepare for this and I really was. Sat in the classroom with a different book to the rest of the class with no support from a teacher who was dealing with 30 other children. Still, I passed with an A. The school had no sixth form so for the next two years I used the time to catch up on homework from other lessons until at some point they gave me an A level text book to work through myself. It nearly destroyed my love for the subject after 2 years wasted.

At sixteen I went to a technical college for A levels, initially studying maths, biology, and physics. In the second week I joined my friends in chemistry without really thinking about it, while the teachers assumed I’d dropped one of the other subjects. The college only offered a single maths A-level, which was half pure maths, a third applied and a sixth statistics. It just didn’t excite me in the way that the science A-level courses were.

When it came to deciding on which Universities and subjects to apply for, maths had been relegated to a support subject and my sights were set on medical physics and biochemistry. I didn’t even look into where a maths degree could take me, assuming accountancy and teaching, neither of which interested me. I was happy with these decisions until I was in Oxford for the entrance interviews.

Three of us had been invited for interviews at St Peter’s college. Myself in biochemistry, Sarah in mathematics, and Anne in chemistry. Anne and I just had a few interviews with tutors before we would be given a conditional offer^{1} we just had to convince the tutors that we would do well. For mathematics, Sarah had an interview and an entrance exam^{2}. To prepare for this she’d been taking extra classes leading to an AS level in further mathematics. Had I not already been doing 4 A-levels I would have joined her. At the end of the first day we were sat in my room and helping her prepare for her exam the next day. My heart sank when I saw the past paper.

Every single question was straight forward to me and I knew I’d made a big mistake. I’d chosen a sensible option rather than a subject I had always loved. While it wasn’t completely too late to change subjects it would have been really difficult to get a place doing maths when all of my applications had been focussed around biochemistry.

So I was accepted to study at Oxford and I spent 4 years there doing the undergraduate and masters in molecular and cellular biochemistry and had an amazing time and learned a lot. But I envied the mathematicians, and loved the more mathematical side of the course I was doing.

When it came to doing a PhD there was a new multidisciplinary neuroscience course starting between Oxford and UCL. This was my opportunity! Combine my love of mathematics with the cellular neuroscience I’d learned. During the orientation, there were a couple of us interested in the theoretical neuroscience PhDs and we had a casual chat with Geoff Hinton. As soon as he realised I didn’t have undergraduate mathematics he lost interest in me and I knew I wouldn’t get an offer^{3}. So I went to Sussex and did my PhD there and learned the maths I needed as I needed it. Fast forward 15 years.

Statistics and data science was part of my day to day job as a CTO but I was missing something. AI hadn’t yet broken into industry, but I knew I’d go crazy if I didn’t do something to stimulate my mind. So I signed up for the OU degree in Mathematics to fill that void.

I started this blog after I’d already done the first three level 1 modules and I was already having difficulty managing the work alongside a full time job and parenting, particularly as I’d just started a new job at a start-up demanding some ridiculous time commitments.

Every year as September came around I’d wonder whether I ought to take a break and concentrate on work. Every year without fail I would sign up for another module with days to spare. Pushing myself because I knew that if I stopped for a year it would be hard to get back into it.

Every module I would get behind, rush the TMAs and then revise in a few days before the exam^{4}. It worked for me, but was a stressful experience at times because I never forgive myself for issues completely within my control so waiting for every TMA and exam result when I didn’t feel I’d prepared enough^{5} turned me into a cranky monster.

This last module result was no different. M347 Mathematical statistics was the “easy option” to end on as it’s literally the statistical methods I use on a day to day basis. But there’s always something new, exam questions that don’t make sense in the moment, or forgetting a proof that means that you might not have done as well as you want. That said, if I hadn’t got a distinction in this module then I would have been embarrassed enough that I would have had to step down from the Royal Statistical Society‘s Data Science Section committee š – fortunately I had the distinction š

It was great to get the email yesterday that I was eligible to receive a degree in mathematics and that it would be a First. If you are thinking of studying go for it – I’ve found the past 7 years tremendously rewarding and am very proud of my achievement.

Hi Janet, I can’t believe this will be your last post on the OU maths degree series! Many congratulations on achieving a first class! I’m certainly going to miss your blog posts about OU maths!

I may do more š I’m not sure what I am going to do next yet and there were certainly other modules that interested me š Best of luck with your studies.

Hi Janet

Congratulations. What an achievement! Well done.

I am too into this (Q77 qualification – Bsc Maths and Physics). Loving it all.

I have just decided on my year 3 papers š

Quantum World

Deterministic and Stochastic dynamics

Relativistic Universe , and

Complex analysis ( I Love pure maths )

Was reading up your posts for a while before I decided to take MS327, since I was thinking whether to take MST326 (Modeling and Fluid Mechanics), but since I had already had a lot of fun and enjoyed MST210, I thought I will take a different one so diving into MS327.

Any particular books (other than the OU ones) you can recommend to me for the above modules, will be greatly appreciated.

Cheers.

Enjoy level 3! They are a great set of module choices. I can’t actually recommend any other books as I did all my study based on the OU books and then used Google if I found I needed something explaining in a different way or to get more examples. The forums and groups on Facebook have people who use other books and will be able to recommend them (or not), as will your tutors. Just be aware of different notation. Best of luck with your studies.
