| Feedback |
The tutorials are an opportunity to get feedback on exam relevant questions. You will get the most out of these by attempting the questions in advance. They are available on learn.
In the first week there is a formative Practical, which will be marked and the results returned to you prior to the hand-in of the second assessment ¿ which contributes to your mark. You will have the opportunity to get individual feedback on the first report in a meeting with the CO, Mark Naylor.
Further subject specific questions can be directed towards the relevant lecturers and/or the demonstrators.

Learning Outcomes
| At the end of this course, you should have a broad, comprehensive overview of the physical processes operating in the solid Earth and its core and a quantitative understanding of the principles of the geophysical techniques by which this information is derived. You will also have gained practical experience and understanding of geophysical exploration techniques and how observations can be interpreted. These practical sessions will give you experience of carrying out routine lines of enquiry into professional level problems. You will be able to critically evaluate evidence based solutions to these problems. The assessed scientific report and degree exams will give you practise conveying complex information to a range of audiences for a range of purposes which is a valuable transferable skill.
