Finding the right tutor
for each child
Step 1: Detailed Consultation
Before we can help a student, we often need to spend a significant amount of time learning about the student's requirements. Most consultations are carried out over the phone or on a video call.
Step 2: Academic Assessment (optional)
Students sit our custom-made academic assessments to indicate their level in relation to their peers, and in order to identify suggested areas to work on. Parents also seek academic assessments for their children to determine their general strengths and weaknesses, and decide upon a set of objectives for the course of tuition.
Step 3: Tutor Selection Process
The selection of the tutor is an integral part of our process. Priding ourselves on how well we know the varying strengths of each tutor, we ensure that each decision is informed by the expectation of a successful match between the tutor and student.
Step 4: Regular Progress Monitoring
After the first lesson, one of our dedicated client managers will contact you to find out how the lesson went. Our client managers are always available at the end of the phone and they are frequently praised for their efficiency, dedication and responsiveness.
Step 5: Monthly Reporting & Feedback
Tutors submit a monthly report detailing the work done in the month; the successes and areas to work on; and the work for the coming month. Our regular, rigorous reporting is frequently praised by parents.

The process begins with an informal academic assessment, allowing the tutor to create a personalised learning plan based on your child's needs. This comprehensive review allows the tutor to build a tailored programme of study based on your child’s ability. The scheme of work will include reviewing past exam papers, practice questions and detailed feedback to ensure your child is thoroughly prepared for their resit exam.
We include mock exams and predicted grades as part of our A Level resit package.
Yes, we offer a trial lesson. With Keystone, you are not required to sign up for any minimum number of lessons, and we offer one-off paid trial lessons so that your child can determine if the fit is right for them. This allows students and parents tutoring through Keystone before committing to regular sessions. The trial lesson is charged at the tutor’s full hourly rate and there is no obligation to continue if you feel it's not the right match.

A Guide to A Level English Language
Is English Language a good A Level subject?
English Language A Level is a really good choice if you have enjoyed the language aspects of your GCSE English course. Students will recall that study for the GCSE Language qualification is what we might call more ‘programmatic’: this is a more technical discipline, requiring a focus on technical aspects of language, and which looks as ‘texts’ that are sometimes a long way from the highbrow and romantic reading of the Literature qualification. It is a modern way of thinking about ‘English’ – as a language and a field of study – that is in some respects a great equaliser. This course elevates advertisements, diaries and scripted speeches to the level of Charles Dickens and Shakespeare: it presents them as all equally worthy of study, equally able under analysis to tell us important things about the way we think and the way the world works. Another way of thinking about and English Language A Level is that it this course presents English almost as a foreign language, divisible into its component parts, into its nouns and syntax features, and whose cultural importance is visible in its contexts of use – and misuse. You will be required to write critical essays, analysing language change and language use; but also to write creatively, producing letters and speeches in much the same way as you did at GCSE.

Keystone Tutors A Level Guide
Advanced Level qualifications, better known as A Levels, help students enter universities or colleges or careers related to the subjects they choose to study. Originally introduced in the UK in 1951, they are also offered in a range of Commonwealth countries, and are normally studied over the course of a 2 year period. Most students will study either 3 or 4 A Levels between the ages of 16 and 19. They are a big step up from the I/GCSE level qualifications students usually take aged 16, and are totally linear courses assessed via exams in the final year of study - typically finishing in June in a student’s final term of schooling. You will normally need a GCSE B grade in the subject you want to study at A Level, as well as 5 A*-C grades at GCSE overall in order to be eligible to take A Levels.
A Levels form a vital bridge between a student’s schooldays and the start of their adult life, and as such they give rise to a lot of questions. Which subjects should I take - especially as this choice will influence the university courses I can apply to? Which careers can I use them for, and how relevant are they to gaining employment? How do I ensure I get the best possible grades? Given the importance of these qualifications answering these questions accurately and getting the right help and support can be incredibly important for a student’s future prospects and success.
Keystone Tutors has put together this comprehensive guide to your A Levels, aiming to help you excel at these essential examinations - we hope you find it useful. We are always happy to discuss specific educational requirements, and the role expert tuition can play in improving performance at A Level - so please don’t hesitate to get in touch.

What are the hardest and easiest A Levels?
There are plenty of opinions on this topic - ranging from the simplistic (it’s Maths, Further Maths, or any of the sciences) to the unhelpful (study what you’re passionate about and you’ll find it easy). Another way in which people frame this commonly asked question is to ask which are the most respected A Levels? Again, there is no straightforward answer - respected by whom and for what? There is no single ‘correct’ answer to these questions, but being clear-sighted about the challenges different subjects bring is a great way to prepare yourself to do well at them, and to remedy any weak spots you have through practice and extra study. Understanding why an ‘easy’ A Level might have that reputation will help you to identify how to truly excel in that subject.
If you are determined to get an answer to the question, no matter how unreliable, a quick Google search will show you plenty of lists of subjects in order of their difficulty as ranked by students - but remember most of these will be unrepresentative polls. If you are interested in the key statistics rather than anecdotal evidence, Ofqual publishes a great infographic which highlights the proportion of A and A* grades awarded at A Level in England by subject. There are some interesting counters in the data to the typical opinions mentioned above - for example over 40% of students taking Maths achieved A or A* grades, compared with 18% of students taking Sociology - and though accurate, neither statistic is much use in helping a student decide between them!
Once again, it’s worth stressing that none of this information is likely to be more relevant to student success than their level of interest and commitment to a particular subject, their willingness to practice and study hard, and the importance of the subject to their desired future career path or choice of university course.
What A Levels do I need for my ideal career?
This is a much better question to be asking than which A Levels are supposedly harder or easier, and the answer varies a great deal depending on the career in question - something which many students are not sure about when it comes to making their choice of A Level subjects.
Some careers require specific degree courses, which in turn require specific A Levels. For example, becoming a doctor requires a Medical degree, which normally require Chemistry and Biology, and many also require either Maths or Physics in addition. You need Maths to study Engineering, and normally another physical science like Chemistry or Physics in addition.
Other courses, like Nursing, will not require a particular A Level but typically prefer students who have taken Biology or a relevant social science like Psychology. Some courses, like Architecture or Law, might seem like they would require particular A Levels, but in fact have no specific requirements.
Researching potential career paths on the UCAS Careers Advice website is a great way to check out the requirements for careers you are considering, and trying to pick a range of A Levels that will keep as many options open for you as possible is a good idea. It’s also worth taking any opportunity you can to do work experience in a range of fields you think might be interesting, no matter how briefly nor how mundane the work you are given may seem to be; this will give you a far greater insight into whether a career is right for you, and hopefully also help you understand how the required A Level subjects may be practically useful to you once you do enter the world of work.
How should I choose which A Levels to take?

Guide to A Level Maths and Further Maths
Should I take Maths for A Level?
Mathematics has been the most popular A Level choice for some time now. This is due to Maths being a highly applicable subject in a range of professions, and is often a requirement for some university degrees. While it is a popular choice, it is also a challenging subject that will require a lot of work to get top marks.
After completing GCSEs, students will have to make the important decision of choosing which subjects they will continue to study for the next two years. Most people do only 3 or 4 subjects for A Level, so choosing subjects that you are eager to study in depth is vital, as you will spend a lot more time with each of these subjects. With this in mind, students should consider whether Maths is the right choice for them from the perspective of ability and interest.
Many schools will only let students take A Level Maths if they achieved a 6 or higher in their GCSE Maths exam, though this may vary at different institutions. If you are on track for a 7,8, or 9 at GCSE, then A Level Maths will likely be within your ability.
Finally, students that are aiming for a certain degree should confirm whether Maths is a required or suggested subject for their course. Potential Maths or Physics students should certainly be taking Maths (and often Further Maths) at A Level, but many other STEM subjects also ask for a strong grade in Maths. For example, courses in Medicine, Psychology, and Computer Science may require students to take Maths or a similar subject for A Level.
