Cambridge Exam Board

Awarding Body: Cambridge

Course Code: 9693

Exams: June and November

Study Hours: 300 – 360 hours

This A’ Level Marine Science Course will provide a coherent and stimulating introduction to the science of the marine environment. The content of the AS part of the course concentrates on the scientific study of the sea and its ecosystems, while the Cambridge International A Level part of the course concentrates on human activities that depend on the sea and have an impact on it.

The course will foster creative thinking and problem-solving skills, which are transferable to any future career path.

The key concepts for Cambridge International AS & A Level Marine Science are:

Observation and experiment

The scientific process of observation and enquiry, experimentation and fieldwork are fundamental to marine science.

The science of water

Water is the key component of the oceans and an understanding of water at a molecular level underpins concepts such as salinity, pressure, density and the availability of key gases and nutrients, which in turn affect the distribution and abundance of living organisms.

Forming and shaping the ocean floor and coastlines

Dynamic interactions between the lithosphere, atmosphere and hydrosphere lead to the development of diverse marine habitats, which are subject to ongoing changes.

Organisms in their environment

The marine biome is the largest biome on the planet and contains many diverse habitats, within which organisms interact with the biotic and abiotic environment. The morphology, physiology and behaviour of organisms are adapted to niches within these habitats. By understanding this diversity, students will have a greater appreciation of the marine environment and the need for its conservation.

Human influences in local and global contexts

Human activities may have a local and global impact. The exploitation of marine resources and the disposal of waste in and around our oceans must be managed if our use of the oceans is to be sustainable for future generations.

You do not need any prior learning knowledge or experience to take this course. This course is openly available to anyone who wishes to take part in a highly rewarding home study course, although you would be expected to have a reasonable standard of literacy.

You have the freedom to start the course at any time and continue your studies at your own pace for a period of up to 2 years from initial registration with the full support of your Tutor. You do not have to wait until September, when a traditional school starts. 

Once you enrol, you will have access to our online portal 24/7. Here you will find study materials that have been specially prepared by your tutor, there will be assessments, study notes, eBooks and assignments all relating to your course. Everything in this course is structured to follow the course specification, so all topics and units cover everything you need to learn. Your tutor will mark your work and give you written feedback on areas you need to improve or explain what you have done well. You can also ask your tutor questions if you get stuck on a topic or need something explaining a little more. 

When you approach the exams, your tutor will set you a series of practise exam papers so that you can know what to expect in your exam, and you can go into them feeling confident.

You will be provided with eBooks for this course. If you want to purchase physical books in addition, then we can provide you with the book ISBN numbers.

Students will be required to arrange and pay for their examinations (including any practicals they wish to take) at an approved centre. We can provide an extensive list of these centres for you.

Most of our A Levels are available internationally. We offer A Levels with three different awarding bodies, AQA, Cambridge and Edexcel. If the course is only available via the AQA awarding body then of course you can still take our course, however the exams must be taken in the UK.

Cambridge, and Edexcel both have international exam centres, so you may be able to take the exams locally to you. Should you need any help, then please do get in touch and we can assist you on this. 

We recommend that you are able to dedicate between 300 and 360 hours’ study time, plus additional time for completing assignments.

Yes, you can work at your own pace to complete this course. Despite having 24 months Tutor Support, once you enrol you will be asked when you wish to complete, and your tutor can work along side you to achieve this.

For example, any A-Level course undertaken has a recommended 360 guided learning hours. Breaking down a 360 hour course into 12 weeks, you would need to be able to commit to 30 hours per week of studying. It is entirely up to you the amount of time you can commit to studying. But with online learning, having the flexibility is a real advantage. This allows you to set the pace. Take your time or Fast-track, get the qualification when you need it.

Yes you will gain UCAS points and these depend on your final grade once you have completed your exams. 

For more information about UCAS points click here

All of our A Level awarding bodies will give you a full A Level qualification. There will be slight differences between the specifications and what you will actually learn. 

For the Science courses (Biology, Chemistry, and Physics), there would be a difference in how you sit practical elements. 

AQA offers practicals but they are optional.

With the Cambridge exam board, you will be expected to perform the practical elements, they are compulsory. Which means finding an exam centre that has a lab for you to complete this. 

With Edexcel, the practical elements are all taught in theory and are assessed via a written exam, therefore you can sit your full exam at a typical Edexcel approved exam centre. 

More information about science practicals can be found here

In most cases yes, what we would ask is for the course codes that you have taken in sixth form/college and we will see if we can match them up. 

In most cases you can, If you go to the individual course page you should be able to see if this option is available for you. 

It is recommended that you aim to book your examinations 4/6 month prior to sitting them to avoid late entry fee charges.  Additionally, we would advise that you contact a few exam centres and find out the best price, as they can fluctuate greatly. 

You will sit the same exam as thousands of students across the country in an exam centre, and achieve the same qualification as everyone else. A-Level qualifications are recognised by the world’s best universities and employers, giving students a wide range of options in their education and career.

Just like sitting your A Levels in a school, your tutor will be able to provide you with predicted grades, and references for university applications. 

Of course, all of our courses are tailored to cover the entire specification and are split into topics. You will have assignments to complete on every topic where your tutor will give you feedback. If you are struggling with an aspect then you can message your tutor and they can provide more information for you.

As your exams approach, your tutor will set a series of exam papers for you to take, so you can get a feel for the real thing.

If you complete all of your assignments, and your practise exam papers then there is no reason why you shouldn’t achieve a top grade.
