Explain why the pancreas is described as both an endocrine and an exocrine organ.

This question requires you to know the difference between endocrine and exocrine glands, as well as knowing the basic functions of the pancreas.
Endocrine = secretes directly into the blood stream(usually hormones)Exocrine = secretes via ducts to a specific place or area (usually enzymes)
The pancreas has a dual function. As an endocrine organ, it secretes insulin and glucagon hormones directly into the blood stream to regulate blood glucose levels throughout the day. As an exocrine organ, it secretes pancreatic fluid (which contains many digestive enzymes) into the pancreatic duct which the enters the duodenum via the Ampulla of Vater.

ROLE PLAY: patient brings you in a gift voucher to go on holiday as a thank you present, what do you do?

In a role play situation you must ensure you speak to the patient with respect but also maintain professional. Within the medical profession gifts are allowed to be accepted only up to a certain value, therefore you have to decide whether you believe the gift is acceptable. For example, a lot of patients may bring in a thank you card or box of biscuits but in this case the gift is a lot more valuable. Ideally in an interview you can't go wrong so long as you explain yourself, therefore accepting usually gift has two ideal answers. Firstly, you can kindly explain to the patient this is a lovely gift but you can accept due to regulations or secondly accept the gift but report it and give it to someone higher up. However, it is vital to notice that in this situation the patient is asking you to go on holiday with them which is not professional and therefore you would have to again kindly explain to the patient you can not go on holiday due to regulations. The patient may ask questions to try and put you off or change your mind but remain calm and repeat yourself. It would be useful in this situation to explain to the examiner that if you felt uncomfortable seeing this patient again you could report the incident.

What is 90 million in standard form?

1 million = 1,000,00090 million = 90,000,000Place your decimal place after the 9 as standard form only has numbers 1-10 as the first number, otherwise it means this number can be divided by or multiplied 10. Move the decimal along until the end of the number and count how many hops you take. (easier to show on whiteboard)9.0,000,000 decimal moves 7 spaces to 90,000,000.Therefore the answer is 9 X 107

What is the difference between Supply and Demand? How do they work together?

Supply and Demand are two economic principles that describe how a good or service is consumed and supplied according to price. Demand refers to the ability of people to purchase a good at a given time and a given price, this usually decreases when price increases. For example you're way more likely to buy an ice cream if its 50p over £5.50? Thats essentially the principle, that people will buy more of a good if it is lower in price! There is an inverse relationship However, this is the opposite of supply, I am way more likely to supply more of a product for a higher price. For example if I sell ice creams, I would rather sell more for £5 than for £2, because i want to make money! The point at which supply and demand meet is an equilibrium price!

What sort of questions I be asked in my interview?

This is a typical question that may be asked by application to Oxbridge. The interviews are daunting and often they are open-ended questions. In my subject area of humanities (Human, Social and Political Sciences), we are asked questions such as "Can a literary competition be fair", "Is tourism a necessary evil", or "Can economists study irrational choice". These types of questions ask the candidate to demonstrate their creative and analytical skills. The questions is based on concepts that the student will be familiar with and purposefully do not have a straightforward answer as they require multiple levels of thinking.
A good way to start preparing for Oxbridge interviews is to begin thinking outside the box, with contemplating and discussing questions such as these. Students may be critically challenged in interviews depending on where they take their answer, and pushed to further engage with the concepts they are presented by.

How significant was parliamentary radicalism in the breakdown of relations between Crown and Parliament in the years 1625 to 1629?

When a question asks how significant one particular factor was to an event, it's advisable to make that factor the key focus of your answer; it isn't asking whether other factors were more or less significant, just how significant this one was. So with that in mind, it's often best to keep one solid line of argument throughout the essay, rather than a 'for and against' style - just decide whether you think parliamentary radicalism was significant or not (based on evidence of course), and run with that.You should start each paragraph with a clear topic sentence that displays what you'll be writing about. For example, something like 'While King Charles claimed that Parliament had radicalised by 1629, this was not the case,' works well because the reader knows immediately what you're arguing in this paragraph. Following that, it's time for some evidence; for this question, you might choose to use parliamentary acts such as the 1628 Petition of Right or the Three Resolutions of 1629, or indeed King Charles' actions, like the 1626 Forced Loan or 1627 Five Knights Case. After you've stated your evidence, it's time to analyse. For instance, you could argue that while Charles saw the Petition of Right as a radical act of defiance against the king, in reality it was just a confirmation of the liberties enshrined in Magna Carta, so parliamentary radicalism was not significant because it simply wasn't there. Do this style of paragraph two or three times, and then end with a conclusion that sums up your argument concisely; a reader should be able to read just your conclusion and get the gist of the whole essay.

Describe the role of situational and dispositional factors in explaining behavior

Heider's Attribution Theory (1958) is a theory based on the assumption that people tend to try finding explanations for other people's behavior. This happens because they are aware of the reasons and causes behind their own behavior and base their own theories of human behavior in this manner. Another reason for attribution is that people are motivated to better predict and understand the environment around them and having personal theories of human behavior facilitates this.There are two types of attributions: dispositional and situational. Dispositional attributions deal with causes within the person, such as personality, intelligence or attitude. Situational attributions deal with the causes outside the person, which means that a certain behavior is caused by the environment around a person (the situation), such as social context or events outside of one’s control.Simmel (1944) showed a tendency of overestimating dispositional attribution in humans observing others. In this experiment, moving geometric figures were shown to participants that then were asked to describe what they saw. Results showed that participants tended to describe the figures’ motions as intentional actions. In other words, they found a causal explanation for what they saw even if conscious intentional motions do not apply to shapes. Evans-Pritchard (1976) showed cultural differences in attribution in Azande people. They believed that witchcraft (a situational factor) was responsible for killing people when a doorway collapsed. While the door had been eaten through by termites, the Azande participants still believed that an external force was responsible for the death of those people.
