Might fail a Constraint of the Project, as usage of the product is largely reliant on the internet and database driven functionalities.
NUS Mods Database can be interpreted as a remote server.

Loop condition used is not phrased in plain english, this is not pythonic code.

Consider using: while new summaries exist.

Developer guide sequence diagram image does not match with the application command

Minor nitpick, diagram should be described as a Class diagram.

Missing user story for required, edit, science, gem and other commands

Missing Termination of Search Command after commandResult is returned

Acceptance Test bug:
The feature does not pass the requirement to help CS students plan for graduation, as there is no check for qualifying for specialisation tracks. Hence it does not fully meet the requirements for managing the requriements for a CS undergraduate as mentioned in the User Guide.

Requirements checking:

Furthermore, many of the validation steps for preclusions, are likely a part of the NUSMODS Database api functionality.

As the point of a sequence flow diagram is to be concise and give the reader a good understanding of the inner workings, consider breaking this diagram up into smaller steps and procedures, building up to the completion of the command.

Similarly with the edit sequence diagram, the excess amount of detail causes it to become conversely complex to understand

Acceptance Testing bug
I can add CS3244 without completing ST2334 first, nor satisfying the preclusion substitutes mentioned in this description below. As such does not help with module planning for module management.
delete ST2334
add CS3244

Suggestion:
Validate that the student has the requisite modules before adding the module into the list. Otherwise, flag out an error.

As highlighted before, this does not follow the stated design of the overall archietecture of GradPad as it is missing an accompanying Parser.
Remedy by: Add justification.

As mentioned previously, the application requires an online querying to validate that a given module does not exist.
Hence this fails as a feature I cannot add an new module that perhaps is a DYOM module not stored on NUSMODS, and is not a feature I can reasonably test. Similarly, what if I have done a module on exchange, and want to add it to my completed list?

Suggestion is to store a portion of Modules offline, or have a mode that is offline, such that features can be tested more reasonably, and allow new module codes to be created.

User Guide states that
The Result Display Box will display the message “2 modules found!” and you will be able to see only the modules whose module codes contain “ma” and modules with “bestmodule” as a tag in the Completed Modules List. But does not specify that it needs to be case sensitive, and finds any substring matching, meaning if i perform
find hh
like below, I return a result as well.

As the diagram here states, there is a CommandParser for each item, however, this command appears to contradict the given archietecture below, with no ListCommandParser accompanying.

Remedy by:
Stating that this command is special and does not follow the usual design pattern specified & reasons for why it is designed this way instead.

Additionally, Termination of List Command is missing in the sequence diagram, after returning commandresult
