This Is the Year That Decides the Grade.

Rated 5 stars on Trustpilot — 30+ independent parent reviews ★★★★★
Year 13 covers as much content as Year 12 — in two terms instead of three. Predicted grades, mocks and the hardest topics of the course all arrive within a few months of each other. The good news is that there is still time to get ahead of it — and the sooner the work starts, the more of that time your child keeps.

Heading for a B When They're Capable of an A*? Here's How to Tell.
After a solid Year 12, it isn't always obvious from the outside. My free guide for parents of Year 13 students covers how predicted grades are set, the two topics that carry a disproportionate share of the final marks, and why the students who finish with the top grades are the ones who get ahead of the school's pace — rather than waiting for a mock to reveal the problem. No obligation, and it's yours in 30 seconds.

Why Year 13 Is Where the Final Grade Is Decided
Year 13 carries the same amount of content as Year 12 — in two terms, not three.
Schools are racing the calendar from the first week of September, and the pressure lands hardest on the most difficult material.
The topics that decide the top grades are often taught last. Differentiation and integration carry a disproportionate share of the marks on the final papers — yet many schools, following the textbook chapter order rather than the exam board's recommended teaching order, leave them until just before study leave.
These topics take months — and more than one pass — to truly master. Knowing when to use the reverse chain rule, or which integration technique fits which problem, rarely lands on first exposure. The students who sit the exam with confidence have met this material more than once.
Waiting for mock results costs time — but a mock is a warning that still arrives in time. For many students the most demanding topics of the course are still to come at school when the mock is sat, so the months after it matter more than the mark itself. The students who recover best act in the weeks around the mock, not in the spring.
Why Getting Help Now Makes All the Difference
Every autumn, the same calls come in — parents of Year 13 students, worried about predicted grades or a disappointing mock, asking whether there is time to turn things around. There is, if we start now. The first job is getting the calculus that carries the most marks — differentiation and integration — in place early, so it has months rather than weeks to settle before the exam.
The students who do best in their final exams are almost always the ones who got ahead of the school's pace during Year 13 — while there was still time to build real understanding rather than cram. Right now there are still months of teaching time before study leave: enough to master the material that decides the top grades, if the work starts now. Every month that passes makes that window smaller.
Our Structured Group Programme Built for
Year 13
This is not drop-in homework help. It is a structured, curriculum-aligned programme that completes the full Year 13 course ahead of the school's pace, following the Edexcel A-Level Maths specification — with the hardest topics introduced early, when there is still time to master them.
A new group opened this term on Wednesday and Sunday at 6pm — places available. Having just completed Year 13 differentiation, it is now starting integration. The Monday and Thursday groups are close to capacity, with a limited number of places remaining. Every group is capped at 10 students, new members can join at any point, and every lesson is recorded.

I'm Lee Guffick — a former Head of Mathematics at a leading independent school, with experience teaching students from schools including Eton College, Westminster School, Brighton College, and Dulwich College. My fifteen-year classroom career has spanned both state and independent settings.
I hold an MA (Distinction) in Educational Innovation with a specialism in Mathematics from the University of Warwick. I am also an active A-Level Maths examiner — marking exam scripts every summer means I see the same gaps come up year after year, and that observation directly shapes how I teach. I'm a Hays Education Award winner.
I've helped hundreds of students achieve results they didn't think were possible. But more importantly, I've helped students who had given up on maths rediscover that they can do it — they just needed the right support.
I am an active teacher at a leading independent school in the West Midlands and I am fully DBS-checked. Nothing makes me happier than seeing a young person who once said "I'm just not good at maths" go on to ace their A-Level exams.
Abdul — Year 13
"Before I started tuition with Lee, I was really struggling with maths at A level. Not just pure but mechanics and stats too, and I was getting in the 40s (around a D) in pure maths in my year 13 November mocks. After a few months of tuition I was able to get 89/100 in my most recent January maths paper 1 mock. I have also improved at stats and mechanics. I truly recommend Lee as he is a great person and tutor and will 100 percent up your grade."
A Sklinitzis
“Lee is a great tutor. He demonstrates a passion for his subject and has an engaging teaching style. Through a combination of group teaching and one to one sessions Lee supported two of my sons to achieve very high grades at A Level. Both were predicted C grades to start with, and finished up significantly better. The sessions are organised and time is managed well to deliver results. Both sons have gone on to secure their first choice at University. The proof is in the results. Difficult maths is conveyed clearly and simply and the boys seemed to progress quickly. Lee is a master class in how to deliver online tuition.”
Ethan
“I had Lee for 3 years through Year 11 to Year 13 and he has been a major help from improving my Maths ability. He helped build my confidence in a relaxed and collaborative environment with the sessions being led mostly by what I wanted to cover. I felt I could ask any questions no matter how trivial or silly they initially seemed and I was always met with an insightful and tailored response to my exact issue. Lee is punctual and very reliable with no last minute cancellations. He gives suggested work to complete between sessions aimed at your weaker areas so be prepared to put the work in to make the most of this incredible tutor. He helped me get an A* in Maths and aided me in getting into my chosen university.”
Lucy
“Lee is an impressive and intuitive tutor. Within a few short moments my daughter was engaged in a wonderful dialogue with Lee based on trust and confidence in his ability. 4 sessions in and we're in it for the long haul; my daughter proactively prepares for her lessons and independently references what she has been studying with Lee. Lee has given my daughter the spring back in her step and it is amazing to see her belief in herself return. Lee's innate ability to connect with students coupled with his professionalism have surpassed any expectations. Thank you so much! ”

How to Get Started
STEP 1
Send me a message on WhatsApp or book a free 10-minute call. Tell me a bit about your child and where they're finding things difficult.

After a brief conversation to make sure the programme is the right match, your child joins a live session as a free taster — no obligation. If it suits, their place in the group is confirmed. No formal assessments or application forms — just a sensible check that we're a good fit for one another.
STEP 3
Within a few weeks, you'll see the difference — in your child's understanding, their confidence, and how they approach the kinds of problems they would have walked away from before.
