Is GCSE Computer Science Hard?

With many Key Stage 3 students contemplating choosing their GCSE options this term, I’m asked again and again is GCSE Computer Science hard? Computer Science certainly has a reputation for being a tough subject, and with good reason. So is it as tough as some people say?

It depends on the student

Now I know that’s a total cop out, but stick with me here. We could just as easily ask ‘is Art hard?’ – for some, absolutely; and yet for others every art lesson is a island of calm in a relentless educational storm (can you tell that I enjoyed art?). If you have a genuine interest in Computer Science as a subject, then the hours of hard work really won’t seem that much of a chore.

Success rates in Computer Science make for some interesting data. Entries at GCSE level increased by 11.8% in 2018, and 3.7% of all students recieved the top grade of a 9. Grade 9s are awarded only to those scoring in the top 20% of the top 20% of grades). Taking into consideration that this was the year group whose controlled assessment was withdrawn at such a late stage, over 60% of all students receiving a passing grade or above is a positive sign.

So in fact, a better question may be: Why do so many people find Computer Science hard?

There are a number of reasons why Computer Science may be a difficult path for you. Not impossible, because there are never any absolutes. And just because something is hard, doesn’t mean we shouldn’t do it anyway.

Your level of maths doesn’t match the syllabus

Calculator mathsWhen the new 9-1 GCSE syllabus for Computer Science was launched, the exam boards advised that students should be studying the higher maths specification to support the topics. Why?

Well, when introducing new students to Computer Science I often describe my subject as just ‘Maths with Toys’. 80% is decision maths, or problem solving, or just plain algorithmic thinking. What do all of these have in common? Maths!

At A Level, the the data shows that a 6 in maths (a B in old money) is an indicator of a pass at Computer Science A Level. This is because there is a huge cross over with Further Maths. Using that as a comparrison, it would be safe to suggest that a target of 6 or more for GCSE maths would predict success in Computer Science.

In the words of Beyonce, without Further maths I don’t think you’re ready for this … Er… Topic.

 

You were expecting to play games

I don’t particularly hold with that view – I am both a programmer and a gamer. However, I am acutely aware of the difference and although knowledge of gaming can help with logic, the likelyhood of playing games in Computer Science is slim to none!

If you’re not sure about what topics are, a good place to start is to look through the specification for the exam board that you will study. Alternatively, have a look through the topic lists on our GCSE Computer Science introduction pages. You’ll certainly be asked to code some simple games during your time studying Computer Science, but it is likely that they will be based around the key topics and will generally be text based.

 

You love programming, but not theory

They race through every programming task that we give them and make an attempt at learning degree level concepts in year 8. If you’re that kid, please know that we love you but you’re an absolute nightmare!

We usually see a lot of ourselves in you, and it’s practically painful not to let you play in the metaphorical ball pit of coding. However, conscience dictates that we must guide you towards success in both the practical and the theoretical aspects of the course. Because of this, we have to ask you to curb some of the enthusiasm for the fun stuff.

Later on, when you’re taking over the world, you’ll come across an issue that suddenly needs an understanding of the mechanics of merge sort. It’s usually then that I get a surprise message via LinkdIn or on here letting me know that our Binary/Hex battles on the board suddenly got context.

The theory topics are complex and often require an understanding of a vast number of key terms, but if you fall into this category, the hardest part is staying on task. Learning to tackle all of the tasks no matter how interesting is a valuable skill and you’ll be able to use it in other subejcts.

 

So, should I study GCSE Computer Science?

Only you can answer that, but as with any subject if you know what’s involved in the course you’ll be able to make a much more informed decision. If you’re still unsure, try a short course like my Introduction to Number Systems to give you a flavour of what the topics are like. Look out for local coding clubs or coder dojos near you, and get involved with Big Bang events as they generally have coding and maker sessions.

Finally, talk to others who have taken the course and your teachers. Don’t just take my word for it!
