Key Stage 5

Although demanding, an A level in Chemistry is recognised as a major achievement. Potential employers value the analytical and conceptual skills that are developed during the study of Chemistry. Such skills, coupled with the ability to work in a meticulous and accurate manner, enable Chemistry students to pursue careers within, or outside, the vast area of Science.

The A level course is divided into 5 modules. Modules 1 and 2 are needed to achieve an AS. All 5 modules are needed for the full A level.

Course Outline

Module Nature of Assessment Assessment Weighting Award Obtained Award Obtained
AS Unit 1 The Language of Chemistry 20%

(50% of AS)

 

AS Chemistry

 

 

 

 

 

A Level Chemistry

AS Unit 2 Energy, Rates and Organic 20%

(50% of AS)

A2 Unit 3 Physical and Inorganic Chemistry 25%

(41.6% of A2)

 

 

A2 Unit 4 Organic Chemistry and Analysis 25%

(41.6% of A2)

A2 Unit 5 Practical Assessment 10%

(16.7% of A2)

Course Content

AS-level Chemistry includes learning about atomic structure, bonding, the Periodic Table, some organic chemistry, energy in chemistry, chemical equilibrium, amongst others. After year 13 you will have a large degree of chemistry knowledge. As shown in the table above you will be assessed by two written examinations. There is no formal practical assessment in year 13.

Having an AS-level in Chemistry broadens your career choice. Many universities see AS-level Chemistry as very desirable, particularly if you have a good range of A-level subjects.

After successful completion of the AS course in year 13 you may wish to continue with a further 3 modules in year 14 and obtain the full A level in Chemistry. The A2 modules are much more demanding than those completed in year 13 and include further organic chemistry and more detailed studies in kinetics, equilibrium, energetics and redox systems.

Career Opportunities

Possible career and course options available to you and your A-level chemistry qualification include: medicine, pharmacy, veterinary science, chemistry, biochemistry, food science/nutrition, forensic science, biological/engineering careers, optometry, microbiology, natural sciences, pharmacology and physiology. Careers and courses that find chemistry desirable include food technology, nursing, physiotherapy, radiography, paramedical courses, law and zoology.

Chemists can:

  • Analyse
  • Make decisions
  • Ask questions
  • Think critically
  • Solve problems
  • Manage information
  • Analyse data
  • Interpret and evaluate evidence

Chemists are:

  • Persistent
  • Methodical
  • Precise
  • Observant
  • Good communicators
  • ICT literate
  • Numerate
  • Creative

Year I left: 2020

Subjects: Geography, Biology and English Literature

As part of the first full GCSE cohort of the school, I left ERGS on a random day in March 2020. Our formal was cancelled and we all expected to be back after a couple of weeks — but we all know what happened next.

I knew the COVID-19 pandemic was going to ruin the typical “freshers” experience, so I deferred my place at Newcastle University to work in my local SPAR for a year. I was sad seeing all my friends leave, but I built up money and work experience that helped open doors for me in the future.

I’d recommend Newcastle to any student. I made some amazing memories and left with a First Class BSc in Environmental Science with Placement, along with an award for the best dissertation in my year.

My placement year was spent as an Assistant Geo-Environmental Consultant at Tetra Tech in Belfast. I worked on some really big projects, including the GeoEnergyNI demonstrator project - the first large-scale geothermal investigation of Northern Ireland.

I am currently studying a Master’s Degree in Forestry for Green Sustainable Development at Linnaeus University in Sweden. There are no tuition fees in Sweden for EU citizens or those with an Irish passport, so I think this is a pathway that should be promoted more often. I really love it over here and everything is taught in English, so don’t worry if your Swedish isn’t up to scratch!

Thank you to Mr Beddard for shouting at me to fix my deforestation homework. It turns out I’m quite good at talking about trees after all!
