Everything you see, hear, smell, taste and touch involves chemistry and chemicals (matter). This broad and complex subject helps us to understand the world in which we live and opens up a range of science-based degree courses and careers.

We think chemistry is fun – no other subject offers bubbles, bangs and changes of colour or state! Our stimulating IGCSE Chemistry online course brings learning to life through a series of practical experiments suitable for completion at home.

Through our course, you’ll develop your knowledge of core concepts across physical, organic and inorganic chemistry, plus key employability skills – such as problem-solving, analytical thinking and reasoning.

Why study Chemistry?

What are atoms made of? Which gases form our atmosphere? How do we extract metal from the Earth’s crust? Studying IGCSE Chemistry online will reveal the answers to a myriad of questions about our world.

With NEC, you can progress at your own pace as you explore a series of engaging topics and undertake practical experiments at home. Perhaps you’ll join previous NEC students who’ve gone on to study chemistry at A level and beyond?

Our Chemistry IGCSE course is ideal if you:

  • Are keen to explore some of the key principles of chemistry.
  • Like exploring ‘big ideas’ that explain the world that surrounds us.
  • Enjoy working scientifically: making predictions, testing theories and evaluating and communicating your findings.
  • Would like to build your observational, analytical and problem-solving skills, to improve your employability.

Future opportunities

  • Studying chemistry or STEM subjects at A level or university.
  • Chemistry develops skills that are well suited to careers in medicine, research, biochemistry, chemical engineering, consumer product development, forensic science, environmental law, pharmaceuticals, space exploration, software design or related areas such as the food industry, technical writing, transportation and education.

Your tutor

You’ll have access to support from a personal tutor. All NEC tutors are subject experts, with experience of supporting online learners.

Meet Jane who is just one of our first-class chemistry tutors:

“I have taught for NEC since the late 1970s on maths, sciences and engineering courses and have also been a tutor for the Open University in technology. Each student has different goals and I aim to help everyone succeed. When students find themselves in difficulty with their course, I endeavour to show them clearly the way to reach the correct answer. I have a Bachelor’s degree in chemistry and engineering. I have conducted research in chemistry and engineering and have a PhD in the latter. I completed the adult teaching qualification Preparing to Teach in the Lifelong Learning Sector (now called Education and Training Level 3). I live in East Anglia.”

What you need to know

  • Edexcel 4CH1


  • Online learning with support from a personal tutor

Entry requirements

  • No formal qualifications are required for this course
  • An ability to read and write in English


  • Complete at your own pace
  • Approx. 120-150*  hours plus time for completing assignments

*The specification suggests that 150 hours is needed. You’ll also need time to complete assignments and prepare yourself for exams and some courses like English literature involve a lot of reading. Everyone is different so it’s impossible to say with certainty how long a course will take you, but you should expect to spend longer than 150 hours. Taken across the length of time we recommend, this equates to approximately 4 hours per week. This will increase if you choose to take it over a shorter time frame or may be less if you are retaking a subject and have covered a lot of of the course content.


  • 11 assignments (one introductory) – these do not contribute towards your final grade
  • 12 core practicals


  • No additional set texts required


  • Internet access
  • Computer operating system and browser to support learn@nec
