Degree: Pharmacy (Masters) - Kings, London University
I am a second year Pharmacy student at Kings College London with a love for science I hope I can pass onto you through our sessions.
I am very understanding and easy to talk to and have previous tutoring and teaching experience from my time in sixth form where I tutored a GCSE pupil who was struggling with the new pressures of deadlines and exams. I have also carried out a year of work experience in a primary school as well as volunteering abroad in The Gambia at a local school.
When we first meet online we will identify where you are at now. This means we will pinpoint any topics you don't feel confident in and explore your current methods of revision and time management.
Each following session will then be dedicated to the topics you don't feel confident in. We will use lots of different techniques to try and get you to soak up the information such as flash cards, posters and diagrams. This will be followed by 10 minutes for questions you may have about the subject in general, homework or any other worries you may have about exams or coursework deadlines.
My motto is 'little and often' so I will encourage you to spend 5 minutes each day learning something from a topic we have discussed, for instance definitions. Then, at the begining of the next session we will spend 5 minutes going through this.
As we progress through our sessions we will review your confidence in each topic. Once you do feel confident in a topic we will start to attempt examination questions as from my experience examination technique is a key skill needed boost your marks.
I aim to make the sessions as interactive and interesting as possible as I believe this makes the information more memorable!
If you think it sounds like we could work together send me a message or book a meet the tutor session.
I look forward to meeting you!

1) A substitution reaction is a displacement reaction. This is when one functional group in one reactant is displaced by another functional group from a second reactant.
This is different to an addition reaction where two reactants add together to form one product.
2) A nucleophilic substitution means a nucleophile is the attacking species.
Nucleophiles are 'nucleus loving' species. Nuclei are positively charged. Opposites attract, therefore nucleophiles will have negative or slightly negative charges.
A nucleophile is an electron pair donor. It will use a lone pair of electrons to form a bond with another atom. This will cause displacement of the functional group originally attached. This becomes known as the leaving group.
To draw mechanisms we just need to learn a few simple rules, example -OH and halogenoalkanes:
1) Identify the nucleophile and the electophile e.g. -OH is a nucleophile. It has a lone pair of electrons localised on the oxygen. This is shown by the negative charge. The slightly positive carbon attached to a halogen in a halogenalkane can act as an electophile. This carbon is slightly positive due to the electron withdrawing effect of halogens.
2) Draw a double headed curly arrow from the lone pair on the nucleophile (O-) to the electophile (C attached to halogen). This represents a new bond being made.
3) When a new bond is made an old bond must break. Carbon can only form 4 bonds.
4) Draw a second curly headed arrow from the middle of the carbon-halogen bond to the halogen atom. This represents the halogen group leaving as a leaving group, taking with it the pair of electrons from the bond. It therefore forms a halide ion e.g. Cl-
5) Draw out your new products - an alcohol and halide ion.
6) TIP - count your carbons! Don't loose any carbon atoms on the way, this often happens when using skeletal formulae.see more
