Personal Description:
Hi, my name's Chris and I provide a guitar tuition service in and around Worcester. I offer both acoustic and electric guitar lessons for beginner and intermediate students of all ages. I teach a variety of styles and can tailor lessons to your own musical interests so that you're not only learning the music you love, but developing other essential skills in a relevant musical context.

Teaching Experience:

I have 12 years experience playing guitar and hold a joint-honours degree in music.

Tutoring Approach:

In addition to teaching you how to play the guitar, I can offer expertise in other areas of music. Having spent three years studying music at university, and being a writer myself, I can assist you with your own compositions, arrangements and songs. Likewise I can help with the sometimes precarious art of accompanying yourself as a singer! The focus of lessons is up to you, though equally if you're unsure of exactly what you'd like to learn I can offer plenty of options. As a patient and considerate individual my lessons tend to be relaxed but highly productive.

Guitar lessons can be arranged at times to suit. I'm generally available on weekday afternoons and evenings but feel free to contact me to check my current availability. I teach at my family home in the Barbourne area of central Worcester but I am also willing to travel within Worcester and to nearby surrounding areas of Worcestershire. For this service I charge an additional fee to cover the cost of transport and travel time, this is 5 within Worcester and 10 for Droitwich and Malvern.

My rate is 15 per half hour, however longer lessons are perfectly possible. For more information, or to arrange a lesson please feel free to contact me.

Personal Description:
I have graduated in Biomedical Sciences from University College London (UCL) with a first class honours. I have obtained excellent grades throughout my education and received several awards for my academic success.
I am currently undertaking a PhD focusing on the immune system.

Teaching Experience:

I have been a mentor for first year university students to help them settle into student life and guide them through their initial year and help solve any problems they may face.

I have also been a tutor for A-level students at UCL Academy where I supported students with their academia and also provided advice regarding university applications.

More recently, I have supervised undergraduate students during my PhD career where I assisted in both the practical and theoretical aspects of science.

Tutoring Approach:

I believe practice makes perfect, and this is the approach I have taken which has resulted in my success.
I would normally teach the concept making sure the student is aware what is being asked and what is being tested. Once the theory has been taught and understood, I would then test this with example questions. After reviewing the answers I would return back to theory to help understand any mistakes made.

I also understand different individuals work in different ways therefore I tailor my approach depending on the tutee.

If you would like further information please do not hesitate to contact me.

Personal Description:
Hey, I'm Vhinoth, currently a third year medical student at Edinburgh university. I'm 20 years old, and from London, where I took GCSEs and A-levels. I have a good academic record, with A*'s in 3 A-Levels and 11 A*'s at GCSE, with a strong background in maths and science.

I took these in England, so I would need a bit of prior notice to brush up on the syllabus here in Scotland, but I am very confident I can help you or your child with their subjects.

Teaching Experience:

I was involved in helping younger students struggling with their subjects whilst at school for a number of years, and helped many achieve their true potential at both GCSE and A-level. I have always had great feedback, and try to engage with my tutees as much as possible.

Tutoring Approach:

My main aim will be trying to help you or your child understand the concepts fully, then going through practice/past exam papers to help them test their knowledge and refine their exam technique.

I will try to to provide a friendly atmosphere, and encourage my tutees to ask questions and to work through problems methodically. I am always happy to be contacted at short notice and to provide feedback on completed work set by me, or by someone else. I enjoy the teaching and I'll be trying to be as helpful as possible. Please contact me if interested!

Personal Description:
I was born in Regensburg, Germany and grew up in Penang, Malaysia. After completing high school (IGCSEs) and the International Baccalaureate (IB) Diploma, I worked at North London Collegiate School Jeju, South Korea for six months as a teaching assistant. After this I attended the University of Melbourne in Australia for my three year undergraduate degree in Environments, majoring in Environmental Geographies, Politics and Cultures. During this time period, I also completed an intensive Mandarin language summer programme at the University of Hong Kong and taught English in rural Thailand during university holidays. I am bilingual, speaking English and German fluently and also speak a bit of Malay, French and Mandarin. I enjoy exploring new places and cultures and am fascinated by languages. I thoroughly enjoy tutoring and teach with a passion.

Teaching Experience:

- A2 and AS Geography (AQA, Edexcel, WJEC)
- GCSE Geography (AQA, Edexcel, OCR)
- University level Geography
- German - all levels including complete beginners and adult learners.

I am currently working (part time) as a Geography teacher in two private sixth form colleges in Ealing, London and St Albans. I teach both A-levels and GCSEs. I have experience of teaching the following exam boards: AQA, Edexcel, WJEC and OCR. Importantly, I am familiar with both the old and new specifications.

I tutored AS and A2 Geography (WJEC Board) at Uxbridge High School in preparation for their exams in June 2016.

I have been working as a private tutor for five years now, alongside my degree in Australia, as well as after, both in Australia and now London. I have had a very large and diverse range of clients. I have tutored university students in Geography and have guided them through essay submissions and exams.

I have also taught on an international level at North London Collegiate School, Jeju, South Korea (as a teaching assistant) and in rural Thailand (as part of a university project).

Tutoring Approach:

Building a strong working relationship and trust between the tutor and student is very important, and being easily approachable is a vital characteristic a tutor should have. Some students may have just lost their inspiration to learn and so it is the tutor`s job to motivate and inspire them. It is important the student is guided on an individual-based level and encouraged to actively engage and think, making links with information explained to them, and not spoon fed. I believe i can bring international experience and diversity to the students i tutor. Especially applicable to Geography, my lessons have a strong focus on exam technique and effective exam preparation.
