Helping GCSE & A Level students master English, boost confidence, and achieve top grades — with 1:1 and group tuition, expert exam marking, and digital study resources you can trust.
Welcome! I’m an experienced UK-based English tutor specialising in online support for GCSE and A Level students. Whether you're preparing for your English Language or Literature exams, need detailed exam marking and feedback, or want flexible digital courses and revision tools to study on your own schedule — you're in the right place.
My approach is kind encouragement, confidence building and ensuring students feel like they know they can succeed in their exams, whatever their ability and background.
Choosing a tutor is such a personal decision! It's trusting someone with your child's education. A good tutor can work wonders with regards to your child's progress, however an inexperienced tutor can also have really negative effects. Knowing your tutor has examined for exam boards is extra layer of security. It shows that your tutor wants to gain a deeper understanding of exactly what gets students marks.
Reviews from parents 🌟🌟🌟🌟🌟
‘My son is currently taking his A Levels and without Sian’s support, encouragement and most importantly
fabulous teaching ability, I can honestly say that we would be in a much more stressful position.
We were fortunate to engage Sian’s services in November 2022, when my son was struggling with content
and structure of his English Language A Level course. My son ‘clicked’ with Sian immediately; her
professional manner and teaching style work beautifully both face-to-face and online. My son’s
understanding of requirements, subject knowledge and (most importantly) confidence have grown
immensely over the past 6 months. We are now looking forward to results day in August, rather than
dreading it!
I can recommend Sian wholeheartedly. Both parents and students will really benefit.
Good luck for the future, Sian, and thank you so much for your help!’
"When I contacted Sian about helping my daughter with her GCSE English,
my daughter’s confidence level was at rock bottom after not getting any
support from her school teacher.
Sian was absolutely amazing with my daughter and not only gave her the
skills and techniques to improve and understand the English questions but
immediately improved my daughter’s confidence 100%.
I would have no hesitation in recommending Sian. Absolutely brilliant and
only sad we don’t need her anymore. Thank you Sian. We are very grateful
for all your help.'
'Sian worked with my son on the run up to his English GCSE
exams. Sian was reliable and well prepared, she was able to
engage a reluctant 16 year old to improve his understanding and
gave him strategies on how to tackle the exam papers. Sian has a
patient and supportive teaching style, her ability to adapt lessons
to his specific needs and provide constructive feedback has greatly
boosted his confidence. I highly recommend this tutor for any
student seeking English tuition.'
