Russell has been providing secondary level maths lessons for my daughter over the summer. She has really enjoyed them and has engaged well, even when challenged. She always comes away from lessons feeling confident in her ability. The pace has been targeted to her and the online tools are easy to work with. She and I would recommend to anyone looking for group or 1:1 lessons.

Excellent tutors, high quality tuition and responsive admin. My son is not in school much due to health issues and the English and Maths tutors are giving him a chance of getting GCSEs. He always seems more confident after a lesson. I highly recommend Greenhill Academic Consulting!

I have had 4 sessions with Noah covering A-Level maths questions. They have been extremely useful at targeting my areas of weakness, which are mainly end of paper questions. Noah is thorough in explanations and make sure I understood exactly what the question is asking. We also covered how to generally approach questions to know how to best answer it. Would highly recommend as tutors!

My daughter had had maths tutoring up to and through her GCSEs. Natasha has been brilliant- they work through complex problems together, identify learning areas and agree topics to cover in their sessions. It’s made a huge difference to my daughter’s confidence and calm approach in maths. Five stars!!!!

Russell has done wonders with my son in an incredibly short period of time. He’s gone from being anxious and feeling unready for his exam to confident and prepared. He’s now even considering A-level maths. I can’t recommend Russell enough.

Tips for working with an IB Computer Science tutor
1
Recognise as soon as possible what you are struggling on and be open about this with your tutor. The tutor will not judge you and will endeavour to help you on exactly the topics that you need. You can use these topics to create goals to work together on.
2
Questions, questions, questions. Either come to the sessions with things that you can ask about or come up with questions during the sessions. You have got time with someone who has dedicated themself to helping students. It’s their job to answer your queries and help you become more confident.
3
Ask for questions to practise with outside of the lessons. Not only does this show motivation and commitment to your tutor, but also it will help consolidate the content from the classes and better prepare you for your IB Computer Science exam in May or June.
4
Take notes from the lessons either by hand or on the computer. No one has the perfect memory and there will likely be a lot of information covered in the sessions, so make sure to write down things that you will need to remember later on. It is possible to record the lessons, so feel free to use this.
5
Aim high and share your goals with your tutor; it’s their job to help you reach your lofty ambitions because they have often already achieved what you hope to achieve. They can help mentor you towards these goals and guide you when you have difficulty with something, even if it’s small.
Frequently Asked Questions
01. My child lacks confidence—how will tutoring help?
Many students struggle with confidence, especially if they’ve had a bad experience in school or feel overwhelmed by the subject. Our tutoring approach helps students build confidence by breaking down difficult topics, reinforcing understanding, and celebrating progress.
02. My child is already working hard—why are they still struggling?
Studying isn’t just about memorising facts; your child must learn how to apply knowledge to unfamiliar contexts, especially in exams. Many students put in hours of revision but struggle with exam technique, structuring answers, or understanding mark schemes. A tutor can help identify and address these specific challenges.
03. How do I know if the tutoring is working?
We track progress through regular assessments, exam-style questions, and feedback from both the student and tutor. You’ll receive updates on improvements, areas of focus, and strategies for further progress.
04. Which exam boards do you cover?
We tutor for AQA, OCR, Edexcel, WJEC and CIE exam boards. We also cover the International Baccalaureate (IB)
05. How do online tutoring sessions work?
We set up a learning space which is joined at the time of a session. In the learning space, students are on video call with our tutors and use an interactive whiteboard with resources. Parents and students are often surprised how easy it is!
06. How often should my child have tutoring sessions?
This depends on their current level and goals. Some students benefit from weekly sessions for consistent progress, while others may prefer more intensive lessons closer to exams. We can recommend a schedule based on your child’s needs.
07. What if my child has a busy schedule?
We offer flexible scheduling, including evening and weekend sessions, to fit around your child’s commitments. Tutoring is designed to be productive and efficient, so even one hour a week can make a significant difference when supported with independent study.
08. Is there a trial available?
Yes! We offer a paid trial so your child can meet the tutor and experience online tutoring before committing. We use the trial to make an assessment and demonstrate how we can help.
09. Why are Greenhill Academics tutors considered the best you can find?
We select tutors with exceptional academic backgrounds, proven experience in helping students reach their goals, and in-depth knowledge of exam board requirements.
10. How do I get started?
