Degree: Natural Sciences (Bachelors) - Cambridge alumni University
Hi! I'm Ivan. I recently graduated from the University of Cambridge with a First Class degree in Natural Sciences, focussing on Biology. I got four A*s and one A at A-Level and have a real passion for science.
Our tutor sessions will be tailored to what you want to achieve, and which aspects you would like to improve. Firstly I will explain the topics and help you understand using a variety of techniques that I have used myself in my own revision. I will aim especially to incorporate good exam technique into each part of the conversation to help you feel confident if the questions come up again.
If you have any questions, then please feel free to send me a 'WebMail' or book a 'Meet the Tutor Session'. Make sure you let me know the topics you'd like to cover, and your exam board.
I look forward to meeting you!

Variation: there is variation in the physical and behavioural characteristics of a set of organisms. This variation is caused by a combination of genetic and environmental factors.
Inheritance: there is a mechanism by which physical and behavioural characteristics may be passed between generations. Some traits may be more heritable (e.g. eye colour), whilst others (e.g. weight) may be more affected by environmental factors.
Selection pressures: in most cases, organisms produce more offspring than resources can sustain. This creates competition for resources (e.g. food, light, or nest space). These selection pressures mean that some individuals will die, as they do not have enough resources to survive.
Differences in survival and reproduction: because there is variation in different characteristics, and there is competition, those organisms which have the most suitable traits for their current environment will be more likely to survive to be able to reproduce. Conversely, those organisms with unsuitable traits are more likely to die. Therefore, some organisms will produce more offspring than others, and their genes will survive to the next generation.see more
The RER is associated with translation of proteins, including protein folding. It is known as 'rough' because it is has ribosomes immersed in it, which makes it easy to remember the protein function.
The SER is associated with the production and metabolism of fats/lipids. The SER does not have ribosomes in it, and so is 'smooth'.see more
