The IB Diploma is one of the most demanding pre-university programmes in the world — six subjects, Internal Assessments, the Extended Essay, TOK, and CAS, all at once. Our specialist IB tutors work one-on-one with students to close knowledge gaps, master assessment criteria, and build the confidence needed to hit their target score.

Tell us about your child's IB subjects, HL/SL choices, and target score. We'll recommend the right tutor and build a personalised study plan that covers subjects, IAs, and Core components.
We pair your child with a specialist IB tutor — someone who's been through the IB Diploma themselves and understands the marking criteria, IA requirements, and what examiners look for at HL and SL.
Your child starts weekly one-on-one sessions online. You'll get regular progress updates, and we'll adjust the approach across subjects, IAs, and the Core so nothing gets left behind.
The IB Diploma demands more than subject knowledge — it requires strategic time management, IA expertise, and Core component mastery. We built our approach to cover the full IB journey, not just the exams.
We're the only tutoring service that covers the complete IB path — from subject selection and coursework through IAs, TOK, the Extended Essay, exam preparation, and university applications. No more juggling multiple providers.
TOK, the Extended Essay, and CAS are mandatory for the IB Diploma and contribute up to 3 bonus points. An E in TOK or the EE means no diploma — regardless of subject scores. Most tutoring services ignore these. We don't.
An epistemology course exploring how we know what we claim to know. Requires a 1,200–1,600-word essay and a TOK Exhibition of 3 objects. Graded A–E — an E means no diploma.
IB students study one subject from each of Groups 1–5, plus a Group 6 subject or an additional from Groups 1–4. We have specialist tutors for every group — including the Arts and Languages that other services ignore.
Group 1
English A: Literature, English A: Language & Literature, and other first languages. Develop advanced literary analysis, commentary, and essay-writing skills.

Every IB tutor in our network has sat the IB Diploma themselves, holds a degree from a top university, and understands the IB assessment system inside out. Several are current or former IB examiners.
Real results from real IB families. These are some of the stories we hear from Diploma students and their parents after working with our specialist IB tutors.
The International Baccalaureate Diploma Programme is recognised by over 5,000 universities in 160+ countries as one of the most rigorous pre-university qualifications available. According to the IBO Facts and Figures report (2024), nearly 193,000 candidates sat Diploma exams in the May 2024 session — a 7.2% year-on-year increase that makes every session more competitive. The global average score sits at 30.32 out of 45 (IBO Statistical Bulletin, May 2024), which means there's significant room for improvement — and that's exactly where focused IB tutoring makes the difference.
What makes the IB uniquely challenging isn't just the breadth of studying six subjects simultaneously — it's the sheer volume of concurrent demands. Students must balance Higher Level and Standard Level coursework, complete research-based Internal Assessments in every subject (worth 20–40% of final grades), write a 4,000-word Extended Essay, produce a TOK essay and exhibition, and fulfil CAS requirements over 18 months. A 2022 study published in the Journal of Research in International Education found that 41.6% of IB students report experiencing anxiety during the programme, with workloads of 30–40+ hours per week cited as the leading cause.
At Roots Tutor Services, we don't believe in piecemeal support. Every IB student who joins us starts with a free consultation where we assess their current levels across all subjects, identify the specific gaps, and build a personalised plan that accounts for IA deadlines, the Extended Essay timeline, and exam preparation. If your child is studying IB Mathematics AA HL, they'll work with a tutor who knows the AA syllabus, the IA rubric, and the difference between a 5 and a 7 on Paper 3.
We're particularly proud of our Core component support. Most tutoring services treat TOK, the Extended Essay, and CAS as afterthoughts — we have dedicated specialists for each. The TOK/EE bonus matrix awards up to 3 extra points, which can be the difference between a 38 and a 41. The IBO's Grade Descriptors document makes clear that an E in either component triggers an automatic failing condition regardless of subject scores — these aren't extras, they're diploma requirements that deserve serious attention.

After every session you'll receive a clear summary of what was covered and what to work on next. We track IB scores and IA progress over time so you're never left guessing whether tutoring is making a difference.
We're confident in our tutors. If your child doesn't improve by at least one IB grade after a full term of regular sessions, we'll provide additional sessions completely free. That's how much we back the quality of our teaching.
Several of our tutors are former or current IB examiners who've marked thousands of papers and IAs. They teach your child exactly what the mark scheme rewards — not just the textbook content, but the precise skills that separate a 5 from a 7.
Most tutoring services treat TOK, the Extended Essay, and CAS as afterthoughts. We have dedicated specialists for each Core component — because those 3 bonus points and the diploma requirement deserve serious attention.
IB students study at international schools worldwide. Our online sessions work across every time zone, with flexible scheduling that fits around your child's timetable, CAS activities, and exam periods.
An independent 4,000-word research essay in an IB-approved subject. Students work with a supervisor across 10–15 hours. Critical Thinking (Criterion C) carries the most marks at 12/34.
Ongoing engagement across three strands over 18 months minimum, with at least one CAS project lasting one month or more. Not graded — but failure to complete means no diploma.
TOK/EE Bonus Points Matrix: An A in both TOK and the EE awards 3 bonus points. These can be the difference between a 38 and a 41 — enough to unlock Oxbridge and Ivy League offers. Our Core specialists help students maximise these critical points.

“My daughter was predicted a 4 in IB Math AA HL and we were seriously worried about her university applications. Her Roots tutor identified the gaps in her calculus understanding within the first session and built a targeted plan. She ended up with a 6 — two grades above her prediction. It genuinely changed her university options.”
Sarah K.
Parent of IB Diploma Student
“I was completely lost with my TOK essay — I couldn't figure out how to structure an epistemological argument. My tutor broke it down into manageable steps and helped me develop a strong thesis. I got an A in TOK, which gave me the bonus points I needed for a 40. I couldn't have done it without Roots.”
Marcus L.
IB Diploma Student, 40/45
“We tried two other tutoring services before finding Roots. Neither understood the IB system properly — they kept treating it like A-Levels. Our son's Roots tutor actually sat the IB herself with a 44 and knew exactly how to manage the workload across six subjects plus the Core. His score went from 28 to 36.”
Priyanka & David M.
Parents of Year 13 IB Student
“My Extended Essay in History felt impossible to manage alongside everything else. My tutor helped me narrow my research question, structure my argument, and refine my academic writing over three months. I got an A on the EE, and the process taught me research skills I'm still using at university now.”
Amira H.
IB Diploma Graduate, Now at UCL
“The IB Chemistry IA was the most stressful part of my DP2 year. My tutor helped me design the experiment, analyse the data properly, and write up the evaluation. She'd marked IAs as an examiner herself so she knew exactly what the rubric wanted. I got a 7 in Chemistry overall — my highest grade.”
Oliver T.
IB Chemistry HL Student
“As a parent, what impressed me most was the holistic approach. Our daughter's tutor didn't just focus on one subject — she helped coordinate the workload across all six subjects, the EE, and IAs. The regular progress reports gave us real confidence. She finished with a 38, up from a predicted 32.”
Catherine R.
Parent of IB Diploma Student
Predicted grades are another critical area where early IB tutoring pays dividends. In the UK, UCAS conditional offers are based entirely on predicted grades submitted in September–October of DP2. Data from the Higher Education Statistics Agency (HESA) shows IB students are 21% more likely to gain entry to Russell Group universities, and strong DP1 performance, solid mock results, and early IA submission directly influence what teachers predict. Once predictions are submitted, they're typically final — making consistent support from DP1 onwards essential for students targeting competitive programmes.
All sessions take place online, which is ideal for IB students at international schools worldwide. There's no commuting, no scheduling headaches, and the flexibility to book extra sessions when IA deadlines or exam season heats up. We also cover mathematics and science beyond the IB, so siblings or students switching curricula are covered too. Because we know parents want to see progress — not just hear about it — you'll receive a summary after every session and regular assessments aligned with your child's school schedule.
