My name is Jack, I currently study Medicine and Newcastle University and have a real passion for tutoring. I took a gap year working in a secondary school teaching GCSE Maths. During this time I took many sessions on improving my teaching styles and sharing my abilities with my colleagues.
I am looking to tutor Chemisty and Biology to A level and GCSE standard and Maths and music to GCSE level. I achieved A grades in all four at A level and A* grades at GCSE.
I would make an excellent tutor for you because of my high level of subject knowledge and copious experience in teaching.
I hope to hear from you soon :)

Mutations in genetic code occur naturally leading to different alleles in genes. (1 mark)
This leads to variation within a species. (1 mark)
Variation provides some individuals with traits which mean they are more capable of surviving in their specific environment, this is known as a selective advantage. (1 mark)
Those with the selective advantage are more likely to survive and reproduce than those without it. (1 mark)
This means that more offspring will be born with the advantageous allele and will out-compete those without it. (1 mark)
Over thousands of years this process will continue and gradually alter the traits of a species in order to make them more able to survive in their environment.see more
Because the highest power of X is 2, this is a Quadratic Equation
When factorised, these look like
(x + a)(x + b) where a & b are constants
To factorise this, we need to find 2 numbers which add together to make the coefficient (number in front of) X and multiply to make the number at the end.
So we need two numbers which add together to make +1 and multiply to make -12 +4 & -3
a & b in the form above are replace by these to numbers, so the answer is
