Chemistry is useful for many degree subjects and essential for medicine, dentistry and veterinary science.
In simplest terms, chemistry is the science of matter. Anything that can be touched, tasted, smelled, seen or felt is made of chemicals. Chemists are the people who transform the everyday materials around us into amazing things. Some chemists work on cures for cancer while others monitor the ozone protecting us from the sun. Others discover new materials to make our homes warmer in the winter, or new textiles to be used in the latest fashions. The knowledge gained through the study of chemistry opens many career pathways. Food, agriculture, materials, petrochemicals, forensic, biomedical, biochemical, bioengineering, chemical engineering, education, geology etc.
Also, in these days of such high competition for the best universities, chemistry remains a highly valued subject which has maintained a challenging and demanding syllabus at A Level and many students have simply used A Level chemistry as a qualification to show their academic ability and gone on to study unconnected fields such as law or accountancy.
