Why do you want to study this course or subject?
A tablet has to survive a lorry, a warehouse, a shop shelf and a stomach before it does anything useful. I first thought about this properly when a customer at the chemist where I work asked me why the soluble paracetamol cost more than the ordinary tablets, and whether it worked better. I could only point her towards the pharmacist, but the question stayed with me: why would you make the same drug in two forms, and what changes when you do? Reading around it afterwards, I found that the answer had less to do with the drug molecule itself and more to do with excipients, disintegration and how quickly the active ingredient can actually dissolve and be absorbed. That gap between a compound that works in principle and a product that works reliably in a patient's hand is what draws me to pharmaceutics. I enjoy chemistry most when it is quantitative and physical rather than purely descriptive: solubility, surface area, rates, the behaviour of suspensions and emulsions. Biology gives me the other half, since absorption depends on membranes, pH and transit times as much as on the formulation. I am interested in how modified-release systems control the rate at which a drug becomes available, and in why apparently small manufacturing changes can alter how a batch performs. I would like a degree that combines laboratory work in formulation and analysis with an understanding of how medicines are tested, scaled up and regulated, because I can see myself working in pharmaceutical development, where the science is careful, practical and directly connected to how well people can take their treatment.
How have your qualifications and studies helped you to prepare?
I am studying Chemistry, Biology and Mathematics at A level, which I chose deliberately for the balance of laboratory skill and calculation. In Chemistry I have most enjoyed kinetics, equilibria and organic reaction mechanisms, and I have become confident with titration, recrystallisation and interpreting infrared and mass spectra. Biology has given me the physiology I will need, particularly transport across membranes, enzyme behaviour and the structure of the digestive system, and I have learned to design experiments with proper controls and to be honest about the limits of my data. Mathematics supports both: I use logarithms and exponential decay comfortably, and statistics work has made me more careful about sample size and variability, which I now notice when I read about clinical or dissolution testing. For my Chemistry coursework I investigated how the disintegration and dissolution of effervescent and standard tablets changed with water temperature and stirring, timing dissolution and measuring pH, then discussing why my simple beaker setup was a poor imitation of a controlled dissolution apparatus. Writing that evaluation taught me more than the results did. Outside the syllabus I have read about excipient function and bioavailability in pharmaceutical science introductions and articles aimed at students, and I follow news about drug shortages and biosimilars because it shows how manufacturing and supply shape what patients actually receive. I revise by making my own problem sheets and by explaining topics aloud to classmates, which quickly exposes anything I only half understand.
What else have you done to prepare outside of education, and why are these experiences useful?
For the past eighteen months I have worked Saturdays and some weekday evenings at a large chemist. Most of my shifts are on tills and shop floor, and I also date-check and restock the over-the-counter medicines, which has made me familiar with pack sizes, formulations and the reasons certain products sit behind the counter. I have learned to be clear about the boundary of my role: when someone asks whether a medicine will interact with their prescription, I take them to the pharmacy counter rather than guessing. Serving people who are tired, unwell or in a hurry has made me patient and precise, and I have been asked to help settle new starters into the stockroom routine because I keep the system tidy and explain it clearly. At college I am one of two students who organise the science society. We arrange fortnightly sessions, mostly short talks and practical demonstrations, and I persuaded a local pharmacist to speak to us about how medicines reach the dispensary. Attendance had dropped to a handful of people when I took over; by moving the meetings to lunchtime and advertising them through tutor groups, we now regularly get around twenty-five, which I am quietly proud of. I also play badminton in a club league on Thursday nights, which keeps me organised and has taught me to lose without sulking. At home I do the weekly food shop and cook for my younger brother on the evenings my parents work late. Between paid work, the society and study I have had to plan my weeks carefully, and that habit is what I will bring to a laboratory-based degree.
