Create a data-to-decision mini report
A clean table, one supported finding, a short written explanation, and a one-slide presentation.
Redesign a poster for five-second clarity
A revised poster using a grid, focal point, aligned edges, purposeful contrast, and tested reading order.
Build your digital learning map
A current strength, one concrete digital goal, an ordered first step, and a fair shared-device routine.
Write a two-source credibility brief
Two independently checked sources with author, date, evidence, bias notes, citations, and a reasoned comparison.
Create a clean file-system handoff
A folder hierarchy, repeatable naming convention, format decisions, compression choice, and recovery explanation.
Code a three-guess number game
A checked comparison function that reports equal, too high, or too low and handles invalid input.
Code a reusable score analyzer
A checked function that averages a list, preserves reusable logic, and handles an empty list safely.
Refactor a messy learner record
A checked function with readable names, explicit type conversion, validation, and focused responsibilities.
Code a CSV-to-JSON category summary
A checked data-processing function with category counts, a predictable summary, and missing-data handling.
Code a resilient API response reader
A checked response parser that validates fields and produces useful outcomes for success, missing data, and errors.
Code a course-progress class
A checked Course class with independent state, completion behavior, validation, and a progress method.
Build a console item-lister capstone
A checked Item class and summary functions designed for validation, persistence, commands, and later charting.
Produce a dataset-readiness report
A variable inventory, quality audit, suitable chart plan, two safe questions, and two claims the sample cannot support.
Build a regression evidence sheet
A candidate line, slope interpretation, residual calculations, train/test boundary, and evidence-based conclusion.
Write a model-selection memo
A comparison of three curves using training and test MSE, with underfitting and overfitting diagnosed.
Design a threshold-and-harm analysis
A threshold choice tied to false-positive and false-negative costs, plus metrics that reveal the tradeoff.
Draw and explain a prediction network
A labeled network with inputs, weights, bias, neuron, output, and a clear explanation of what training changes.
Create an overfitting diagnosis log
An epoch-by-epoch loss reading, the likely overfitting point, and one justified tuning experiment.
Build a safe professional presence plan
A public/private content map, one evidence-based profile improvement, and a respectful networking message.
Create a shared-workspace handoff kit
A folder map, naming rule, permission decision, shared-document plan, and concise handoff email.
Build an automation decision blueprint
A working trigger-to-action simulation with mapped data, a failure path, and human review.
Build a credibility-first portfolio page
A phone-ready page with clear purpose, useful evidence, predictable navigation, and a working action.
Code a budget-warning calculator
A checked Python function that calculates product totals, compares a budget, and rejects invalid input.
Code a portfolio project index
A list of project dictionaries formatted into a readable portfolio index.
Produce a human-reviewed AI biography
A safe professional bio with every claim checked, revisions explained, and private information removed.
Create a targeted application package
A quantified resume bullet and five-sentence professional email tailored to one real opportunity.
Complete a safe profile audit
A trust-and-privacy audit with one evidence improvement, one safety correction, and one networking action.
Build a shared project workspace
Three purposeful folders, named files, tested permissions, a current document, and a clear collaborator handoff.
Simulate a classroom registration workflow
A working registration queue with mapped fields, visible confirmation, validation, and a human fallback.
Build a trustworthy community website
A semantic, responsive page with predictable navigation, clear proof, a working action, and phone support.
Code a learner score checker
A checked Python function that personalizes a next step from a learner name and validated score.
Code a shop inventory tracker
A checked list-of-dictionaries inventory that updates quantities and reports low-stock products.
Run a verified prompt experiment
A vague and improved prompt, a side-by-side output comparison, two verified claims, and a human revision record.
Demonstrate a complete computer system
A labeled input-process-storage-output map plus a safe startup, use, and shutdown demonstration.
Redesign a confusing sign-up screen
A clearer screen with visible purpose, eligibility, privacy guidance, accessible labels, and honest feedback.
Create a professional social launch pack
A purpose statement, three supported skills, one proof-of-work post, a safe call to action, and review notes.
Complete a prompt-and-verification experiment
Two prompt versions, an annotated comparison, one independently verified claim, and a responsible-use decision.
Design a community event poster
A one-page poster with one headline, three details, one action, a limited palette, and a five-second test result.
