Six modular units, three exam series a year, and two written practical papers most families don't plan around. We tutor unit by unit - molecules, cells, physiology, ecology and the practical-skills papers - to the exact combination your child is taking.
A simple four-step approach designed to build confidence, close gaps and improve exam performance.
We confirm the syllabus code, exam series and paper route for YBI11. Everything else depends on this.
A diagnostic against the syllabus topics tells us what's secure and what isn't, so we teach the gaps rather than the whole book.
The same tutor teaches each week around school. Concepts build step by step, with the school's pace kept in view.
Past-paper questions begin early, followed by full timed papers marked against the published mark scheme.
Expert, vetted Edexcel International A Level Biology tutors who have taught the YBI11 specification. Past-paper work is reviewed against published mark schemes, so your child can see where marks are awarded and where they are being lost. UK-qualified teachers are available on request as a premium option.
Not "edexcel international a level biology in general" - this syllabus, this tier and these papers.
Your child learns where the marks actually are, not where they feel they should be.
Shared whiteboard, worked solutions and lesson materials saved to review after the session.
The same tutor every week - and if that changes, we tell you first.
The qualification is fully modular. Four theory units and two practical-skills units make up the full International A Level, each a standalone written exam that can be banked and resat toward the final grade. Practical skills are assessed on paper, not at the bench.

Units can be sat in January, June and October, and any unit can be resat. Practical skills are 100% written assessment in Units 3 and 6.
None of these are about ability. Each one is a mechanism in the exam, and every one of them is trainable.
Units 3 and 6 are examined on paper - experimental design, statistics and the pre-release core practicals. Students assume they'll pick the marks up and skip the drilling.
Modular freedom means an early, under-cooked unit sits in the aggregate untouched. Many families don't realise it can be resat.
The mark scheme credits exact terminology, not the general idea. Students who know it but phrase it loosely lose marks on the extended-response questions.
Units 4 and 5 carry the top-grade marks and draw across the whole course. Students who coast after AS find the A* lives there.
The practical and synoptic questions lean on interpreting unfamiliar data and applying statistics. Content-confident students slip here because it was never separated out and practised.
These are the main syllabus strands your child is expected to cover. We teach all of them, starting with the gaps that are costing marks first.
Tuition stays aligned to the exact paper or unit structure, so revision time goes where the marks actually move.

Six units: Units 1, 2, 4 and 5 are theory papers, and Units 3 and 6 assess practical skills by written exam.
Yes. Each unit is a standalone exam that can be banked across sessions and resat to improve the grade.
By written exam, in Units 3 and 6. There is no separate lab exam.
The full International A Level is graded A* to E; International AS is graded a to e.
Units are available in January, June and October.
Biology is marked on precise terminology and on interpreting unfamiliar data. Both are skills, not just knowledge.
We replace them - free, and with no argument - and hand over the unit-by-unit progress and known concerns so the new tutor continues seamlessly.
Yes. The biology overlaps heavily; the difference is structure - Edexcel's bankable modular units with written practical papers, versus Cambridge's papers-together model with a live lab exam.
