IB Mathematics Analysis and Approaches (AA) SL Internal Assessment Example

Your exploration is clearly structured and easy to navigate, with a strong introduction, separate modelling sections, and a conclusion that helps the reader follow your reasoning.

You keep the work mostly relevant to the aim, and the inclusion of graphs, tables, and limitations makes the presentation feel purposeful.

Your section-by-section development gives the investigation a coherent flow from data collection to model comparison.

Some visual elements are small or repetitive, which makes the presentation less polished than it could be.

A few parts repeat ideas that do not add much mathematical value, so the work is not as concise as it could be.

The conclusion would be stronger if the final comparison between models were made more decisively and clearly.

You use appropriate mathematical language for functions, parameters, fit statistics, asymptotes, and percentage error.

Your work includes a strong range of representations, including tables, scatter plots, fitted graphs, equations, and numerical measures of fit.

Your explanations generally help the reader understand what each mathematical step is doing, rather than leaving the calculations isolated.

Some wording is mathematically imprecise and should be tightened for accuracy.

The graph images are somewhat small, and a clearer presentation of labels or equations on the visuals would improve communication.

The comparison of fit measures is not always explained with enough precision, so the reader is left uncertain about how model quality is being judged.
