The student reviewed many existing methods as well as the literature to understand the various sub-domains of the executive functions, namely, planning, decision making, working memory, responding to feedback, inhibition, and flexibility. Chapter 2 reviews the brain anatomy in section 2.1, the six cognitive skills in section 2.2, and provides details of the human executive functions with its sub-domains in section 2.3. Section 2.4 discusses the existing methods to measure each one of them and provides the summary of the various batteries for the assessment of executive functions. The chapter is concluded by providing details of the gaps and the corresponding way forward.

The work was challenging because the development included backend database development on the cloud, frontend user interface development, and the visualization of the results. In addition, the student also proposes evaluation methods for the results (as can be seen on page 27 of the thesis). The student worked hard to complete all the development in time and he was able to submit the thesis before the deadline. He regularly consulted me before the submission of the thesis.

The author adheres to the recommended structure, and the subsection hierarchy (x.x.x) is logical in most cases. The length of each chapter is adequate. The research into various test types and the selection of three specific tests to represent the broader set of cognitive functions are commendable.

However, introductory text in chapters or sections are either missing or insufficient. There is a tendency to repeat already established knowledge, which fatigues the reader. There is an insufficient number of illustrations. Extended abstract is missing. 

The delivered software solution is well-structured, logically divided into Frontend and Backend components, and can be successfully deployed using the instructions in the root README.md file. The author detailed the structure thoroughly in the thesis and utilised modern routing practices. Network communication and unexpected errors are adequately handled. The utilised libraries are properly cited within the work. Moreover, the solution's intuitiveness and simplicity were validated through public user testing, resulting in actionable improvements to the user experience. One of the breakthroughs of the implementation is the scoring system for the tests, which tracks the difficulty of the individual task. It was developed by the author.

The implementation could be more commented as the React code tends to be longer. 

Evaluation level: assignment fulfilled

The author successfully met the assignment requirements. Initially, they acquired in-depth knowledge regarding human executive functions, cognitive tests, and their gamification. Literature Review chapter detailed various techniques, tests, and their respective limitations. Ultimately, the author proposed and developed a custom mobile application to measure the brain's executive functions. Following implementation, human experiments were conducted to evaluate the application's quality, yielding questionnaire data from participants for subsequent analysis and application refinement.

The author utilized relevant sources to grasp the established domain knowledge. Borrowed figures are properly cited, and the citation formatting is correct.
