How Do You Prepare for the MYP Chemistry eAssessment?

Prepare by practising past on-screen eAssessment tasks under real time pressure, revising all four criteria (A, B, C, D) equally, and learning the interactive tools — drag-and-drop, simulations, data tables — before exam day. I tell every MYP 5 student I teach: the science is rarely the problem, the interface is.

The MYP Chemistry (Sciences) eAssessment is an on-screen exam combining multiple-choice, short-answer and extended-response items, often built around unfamiliar stimulus material — a scenario, data set or experiment description you haven't seen before. It assesses all four MYP Sciences criteria in a single sitting, typically lasting around two hours.

The on-screen Sciences eAssessment runs for roughly two hours, though exact timing is set by IB and can vary slightly by session. Pacing matters more than raw speed — students who plan roughly 20 minutes per major stimulus set tend to finish with time to check extended responses.

The eAssessment is marked against the same four MYP Sciences criteria used in classroom assessment — A: Knowing and understanding, B: Inquiring and designing, C: Processing and evaluating, D: Reflecting on impacts of science. Each criterion is scored 0-8, giving a total out of 32, which converts to the final 1-7 MYP grade.

A grade 7 typically needs a total in the high 20s to 32 out of 32 across the four criteria — exact boundaries shift slightly each session because the IB sets them per assessment cycle. Consistent strength across all four criteria matters more than being brilliant at one and weak at another.

In my experience marking mock papers, Criterion C — processing and evaluating — costs students the most marks. It asks you to identify trends, calculate uncertainties, and evaluate the validity of a method, and most students under-practise this compared with content recall (Criterion A).

The eAssessment draws from your full MYP 4-5 chemistry course — particle theory, atomic structure, periodicity, chemical bonding, reactions and stoichiometry, and acids/bases — since the stimulus is unfamiliar and can combine topics. Examiners build scenarios that force you to apply several units together, not recall one in isolation.

Practise by working through topical worksheets that present a new context each time — an unfamiliar reaction, an unusual dataset — rather than only redoing questions you've already seen. The skill being tested is transferring known chemistry to a new situation, so variety in practice matters more than repetition.

Manage time by allocating minutes per stimulus set before you start, flagging and returning to extended-response questions rather than getting stuck, and leaving the last 10 minutes purely for checking calculations and units. On-screen exams make it easy to lose track of time without a visible clock, so watch the timer.

The biggest mistake is revising content (Criterion A) almost exclusively and ignoring inquiry and evaluation skills (Criteria B and C), which the eAssessment weights equally. According to the IB's MYP: From Principles into Practice guide, all four criteria carry equal maximum marks — so a content-only revision plan structurally caps your grade.

You can help most by protecting exam-format practice time in the weeks before results — a full timed mock, done on-screen, matters more than extra tutoring hours. Ask your child's school which eAssessment window applies and whether practice access to the on-screen tool is available in advance.

The MYP eAssessment grade sits on your child's MYP Certificate and doesn't gate entry to the IB Diploma Programme directly, but strong criterion-based habits — especially data evaluation and scientific reasoning — carry straight into DP Sciences, where the same command terms and criteria structure reappear.

Useful resources are ones that mirror the actual assessment: unit-by-unit revision notes for content gaps, topical worksheets built around unfamiliar stimulus questions, and full timed mock papers in an on-screen-style format. On RevisionPrep, MYP Chemistry students get all three, organised by criterion rather than just by topic.
