FRQ 1:

Part A: The code correctly makes the arraySum function and shows understanding of for loops. Part B: Shows understanding of using previously written methods and for loops, and indexing arrays. Part C: Uses nested for loops effectively to compare elements and determine if the array is diverse. Returns the correct value indicating diversity. Reflections: The reflections provide helpful insights into the problem and how it was approached, showing a strong understanding of the question overall. Score: 0.85/0.9

FRQ 2:

General: The use of Scanner for user input testing is an interesting approach, allowing for exploration of Java concepts beyond the course curriculum. General: The choice of StringBuilder over conventional String manipulation methods is intriguing, with a clear explanation provided. The HiddenWord class constructor is well-implemented, with appropriate instance variables and constructor arguments. Effective use of conditional statements to concatenate StringBuilder, demonstrating a solid understanding. Reflection: Insightful reflection on memory efficiency and the immutable nature of strings, along with an interesting suggestion to add interactivity to the program. Score: 0.9/0.9

FRQ 3:

General: The inclusion of the addEntry method aligns well with the example code, providing an insightful enhancement to the program. Part A: The for loop effectively locates the matching element in the entries ArrayList, with the conditional statement implemented insightfully. Part B: The addition of the toString method to SparseArrayEntry facilitates easy printing and testing, although in the context of the problem, it's advisable to refrain from altering the template code. Part B: The use of the iterator pattern to manipulate values within the entries ArrayList is commendable, meeting all requirements of the problem. Reflection: Insightful reflection on the challenges encountered during problem-solving adds depth to the discussion. Score: 0.85/0.9

FRQ 4:

Part A: IntegerList implements NumberGroup interface, overriding contains to check for number presence. Part B: Range implements NumberGroup, determining if a number falls within the range. Part C: MultipleGroups implements NumberGroup, iterating through groups to check containment. Reflection: The code effectively defines classes to check if a number is within certain ranges or lists of numbers, showing how to group numbers and check their presence efficiently. Score: 0.85/0.9

Connections Review

He discussed the relevance of each Free Response Question (FRQ) to his project, covering topics like arrays, ArrayLists, classes, methods, and control structures. He pointed out potential enhancements to his project based on the recently finished FRQs. His report offers comprehensive insights into the coding aspects, incorporating examples from his project. He demonstrates the application of Collegeboard principles in his project-based learning (PBL) and reflects on possible enhancements for each type of FRQ, proposing practice recommendations. Nonetheless, there's room for a more in-depth exploration of the connection between Collegeboard concepts and his project, along with further suggestions for improvement.

Score: FRQ: 3.45/3.6 Association: 3.6/3.6 7.05/7.2
