Student results
IB Doctor reports a 2.3 grade improvement as an internal historical average for relevant sustained-support students, particularly those using structured exam preparation such as the Assessment bundle. It is evidence of past reported outcomes, not a guarantee or independently audited study. Results depend on starting level, effort, subject, timing, school context and how consistently students apply tutor guidance.
The sample is useful for identifying whether students receiving sustained tutoring often move from lower confidence and weaker predicted grades to stronger assessed performance. It helps parents understand the type of progress IB Doctor is trying to create: fewer syllabus gaps, better exam technique, clearer coursework methodology and more disciplined revision.
The sample does not prove a guaranteed causal result for every student. IB outcomes are influenced by school teaching, mocks, deadlines, student effort, prior attainment and assessment conditions. IB Doctor therefore presents the 2.3 grade improvement claim with context rather than as a promise.
