I have noticed on this forum that there are a lot of people like myself, who are perhaps slightly mathematically phobic and worry about being able to handle the mathematics on their course. I can only speak for the introductory course MU123, however as this covers a substantial amount of pre calculus content it is a fairly thorough introduction to the subject.
If, like me, you have opted to move down the path of an engineering or science based degree, then it's inevitable that you're going to have to learn mathematics. I was very worried when I began, thinking perhaps I was unable to do the work involved because my brain wasn't mathematical. My mind would flit back to long division and multiplication and other life ruining memories from school and I would think "I am just useless at maths, clearly I am just no good at it and I will never be able to do it".
Well, as the world's worst student of mathematics, I am happy to say that this is absolutely wrong! I am now solving problems that looked like an alien language before I started. Is it because I found out that secretely I have the mystery gene that enables me to perform vast computations and mental gymnastics? Absolutely not. It's because I sat down for a few hours every other night, and spent time improving my ability and knowledge of one of the most fascinating subjects around.
At the level of MU123, you are simply learning a few simple rules that apply to how numbers work, practising the application of those, then moving on to the next section which builds upon those rules further. I have no doubt that there are areas of mathematics which require immense mental gymnastics (though I am assured by a friend of mine who graduated with a BSc Mathematics, that the study of the subject actually continues in a linear fashion, slowly building up knowledge in the same way one might learn to drive).
Are you ready for MU123? (Yes!)
Here's a problem for you. If you can solve it by following my instruction, then you're ready to begin to MU123.
5 + 2 * 3
In arithmetic, you carry out the multiplication (which I've outlined in bold) first. After completing the multiplication, you then carry out the addition.
So, first we work on 2 * 3, which is the multiplication aspect of the problem. 2 * 3 is 6, so we can reduce the problem to:
5 + 6 = 11
There, you've solved a problem using the order of expressions rule and got the correct answer. You're ready for MU123.
I want to discuss the content and make up of the course in a bit of depth, because I know there are often a lot of questions before starting an OU degree as to how the assessment works. I will focus specifically on the grading style of MU123.
How does assessment work?
Assessment on MU123 comes in two forms. The Tutor Marked Assessment (TMA), and the Interactive Computer Marked Assessment (iCMA). There is no exam, and you can complete the TMA questions whilst you cover the relevant sections in the course materials, at home. They simply needed to be posted to your tutor on or before the due date.
The TMAs are weighted as follows:
TMA01: 15%
TMA02: 20%
TMA03 - 30%
TMA04 - 20%
The iCMAs, of which there are also four, act like a piece of formative work in the form of a multiple choice quiz which covers most of the same content as the upcoming TMA. The weighting for the iCMA's is quite low, and my tutor even told us that some people that don't bother to do them go on to get Firsts. I believe they are worth doing well on because they give you confidence for the TMA material.
The TMAs are roughly evenly spaced throughout the course. So, as an example, your first couple of months will play out like this:
Weeks 1 and 2 - Working with numbers.
Weeks 3 and 4 - Negative numbers and fractions.
End of week 4 - iCMA due which covers material on first four weeks.
Weeks 5 and 6 - Thinking mathematically.
End of week 6 - TMA01 due.
Then you'll start on week 7 and the same process will begin.
The structure of the course
Finally, here is an overview of what you will be covering on the course. The pace is fairly relaxed, however if you take it alongside other modules make sure you stay up to date with the material, because I've found it's very difficult to cram with mathematics.
Unit 1 - Starting points
Unit 2 - Mathematical models
Unit 3 - Numbers
Unit 4 - Statistical summaries
Unit 5 - Algebra (this is where it gets interesting!)
Unit 6 - graphs
Unit 7 - Equations and inequalities
Unit 8 - Geometry
Unit 9 - Expanding algebra
Unit 10 - Quadratics
Unit 11 - Statistical pictures
Unit 12 - Trigonometry
Unit 13 - Exponentials
Unit 14 - Mathematics everywhere
So there you have it. Some of that stuff looks complex, and initially it is. But if you can solve 5 + 2 * 3, you're in a great position to start the course, and to enjoy what has been the most genuinely stimulating and fascinating subject I have ever studied. And that is coming from a guy that got a G in GCSE Maths 11 years ago.
I hope this has alleviated your nerves and maybe even persuaded you to go on and study a science or engineering degree with the OU. If I can do it, anyone can!
