CET131 is a software engineering assignment built around a fictional car rental company that needs a standalone application for staff to rent out vehicles. The deliverable is a report of UML diagrams, not code: a detailed use case for the booking process, a flowchart for login and credential checks, and a class diagram.
Each diagram carries a set share of the marks, and the use case carries the most. We draw all three so they agree with one another and with the booking rules in the brief — customer details, licence check, rental length limits, car and fuel types and optional extras.
What we help with
Use case — A detailed use case for the booking process, with actors, preconditions, the main flow and the alternative flows for failed validation.
Login flowchart — A flowchart for staff login and credential validation, with every decision branch covered.
Class diagram — Classes, attributes and methods that match the data and rules in the brief.
Consistency — Names, data and rules identical across the three diagrams.
Report format — A clean report with the diagrams labelled and explained, ready for digital submission.
Plagiarism and AI reports, issued with the work
Similarity and AI writing indicator reports come with every delivery, and we run them on work you wrote yourself too. You get the reports and the explanation, never a bare figure.
Similarity report, not a number — Every draft is checked before it reaches you and the full report is issued with the file — matched sources listed, each flagged passage identified. A percentage on its own tells you almost nothing about what a reader will conclude.
AI writing indicator read — Where your institution's configuration produces one, the AI indicator is reported alongside similarity and read back to you. The two scores are separate, they behave differently, and a low similarity figure does not mean you are clear on the other.
Every flagged passage explained — Each match classified — quoted material, a standard definition your discipline cannot avoid, a bibliographic match, or text that genuinely needs rewriting. The explanation is what lets you defend the work if you are asked about it.
Checks on work you wrote yourself — Send a draft we had no part in writing and you get the same pack back: both reports, the flagged passages explained, and an honest read on whether an AI flag looks like a detector artefact. This is a service in its own right.
Run while you can still act on it — Pre-submission checks are worth having early, chapter by chapter on long documents. A report that arrives the night before a deadline tells you about a problem you no longer have time to fix.
No guaranteed percentage — We do not promise a similarity figure or an AI score, and we will not rewrite work solely to move a detector. Any service quoting you a guaranteed number is describing an output it does not control.
We are an independent academic support service, not a university and not a reseller of any detection platform. We run checks and issue the resulting reports; we do not sell access to a detection tool, and we do not sell a way around one.
Not sure if your work has plagiarism? Don't worry. Send it to us.
Tell us what you need checked and when it is due. Your document is checked without being stored in any student-paper repository, so the check never counts against your real submission. The reports come back with what each match means, not just a percentage.
Plagiarism report — The full similarity report on your assignment, proposal or chapter: every matched source listed, every flagged passage marked, and a plain read of which matches matter and which are your reference list doing its job.
AI report — The AI writing indicator read separately from similarity, because the two scores behave differently. If the flag looks like a detector artefact on work you wrote yourself, we tell you so, and what evidence answers it.
Thesis report — Similarity and AI reports for a full thesis or dissertation, run chapter by chapter so a problem in the literature review is found while you can still fix it, with each flagged passage explained for your supervisor.
Frequently asked questions
Do I need to write any code?
No. The brief asks for UML diagrams for a fictitious system, so the work is modelling, not programming.
Which tool do you draw the diagrams in?
Whichever your course uses. We can supply them as images or in the editable tool you were taught.
Is your service confidential?
100%. Your identity and academic work stay completely private and are never shared with your college or anyone else. We use secure, encrypted communication.
