Criterion A: The topic of the Internal assessment is stated clearly and explained in the introduction

Comment: The student directly states that they will investigate which loan types are most preferable and analyze their sustainability

Criterion A: The introduction includes a general description of the student's approach to the topic and what area of the math curriculum the exploration focuses on

Comment: The areas of mathematics (specific concepts) used in the exploration are not described in the introduction. The student should include the descriptions of the sequences in the work as well as induction and functions

Criterion A: The conclusion is a summary of the outcomes and a response to the aim of the exploration stated in the introduction

Comment: The student provides a direct answer to the research topic and states what kind of loan is the most preferable as well as sustainable

Criterion A: The use of technology, when applied, is clearly indicated and explained

Criterion B: Computer notation is present only if software-generated (clear indication necessary)

Comment: The student should include the fraction instead of the division sign

Criterion B: Key terms/variables are defined and explained when first introduced

Comment: To make sure the criterion is fully fulfilled, the formula for a geometric sequence could be defined, as the term is used repeatedly throughout the work

Criterion B: The degree of accuracy is stated for any rounded values

Criterion B: The degree of accuracy is stated for any rounded values

Criterion B: The degree of accuracy is stated for any rounded values

Criterion B: The student used a deductive method and set out logical proofs where appropriate

Comment: The mathematical induction process is not described in detail, but as it is not the main focus of the exploration but only a tool to prove the validity of its part, it is not a mistake. Most importantly the proof is logical and includes the most important statements
