About My Feature:

The feature that I worked on for the past few weeks is a reading list displayed on the profile. Users are able to add books to their list, and are able to mark each book as you progress through it. They are also able to see the date they added the book, and to check if the book is available to be checked out. You can also delete the book if you don’t want it anymore. It gets the books from the main book database, and adds the books to the Wishlist table. It has all the CRUD operations, fulfills all the CB requirements, and API’s that function properly on the deployed website.

5 things I accomplished over 12 Weeks:

making a table within a database using Model
learning how to use token_required and returning a list unique to each user
using multiple API routes for my feature and testing them on Postman
learning how to communicate on a team and how to enhance cohesion and unity
the importance of planning with kanban boards, burn downs, etc.

Kanban Board This kanban board helped our group get tasks done and check our progress.

Burn Down This burn down was specific to my feature, and I added to it when I wanted to change something and checked things off when I completed them.

Figma Board This flowchart is one of our planning documents and it provides a visual so that our group understands how the code is supposed to function.

N@tM Event + Feedback

At N@TM, I got to share with many students and parents our Bookworms website, and we were able to get some feedback on it. Overall, people agreed that our styling was good and our website was cohesive. The things we can work on are mostly formatting issues and improving our talk.

Things we did well:

Things we could improve on:

Other Projects:

I took an interest in two other CSP projects, including Michelle’s group about travel places and Prajna’s group about food.

I liked the website about traveling because it’s a functional website that can be used in real life, and it had cool features such as recommended vacation spots that are good for travelers.

The project about food and food rating was interesting to me because it can display food from all around the world, and the user can provide their own review of it, similar to Yelp. I was also able to provide feedback on it and interact with their project.

CPT requirements:

Input:

The user enters the book they would like to read through a dropdown menu, and also edit their progress through the book.

Dropdown list of books:

<label for="bookDropdown">Select a Book: </label>
<select id="bookDropdown">
  <option value="">--Choose a book--</option>
</select>
<button id="addToWishlistButton">Add to reading list</button>

Reading status dropdown:

const statusDropdown = document.createElement('select');
['for later', 'in progress', 'finished'].forEach((status) => {
  const option = document.createElement('option');
  option.value = status;
  option.textContent = status;
  if (status === book.status) {
    option.selected = true;
  }
  statusDropdown.appendChild(option);
});
statusDropdown.onchange = () => {
  const newStatus = statusDropdown.value;
  const newAvailability = book.availability;
  updateBookInWishlist(book.id, newStatus, newAvailability);
};

List:

I use a list of dictionaries to create a list of books that eventually get displayed in the dropdown menu.

    books_list = [{'id': book.id, 'title': book.title, 'author': book.author} for book in books]

#### Sequencing: My code uses sequencing because the code executes line by line, importing modules, defining the blueprint, and declaring routes

 # Create a Blueprint for the wishlist functionality
wishlist_api = Blueprint('wishlist_api', __name__, url_prefix='/api/wishlist')

Selection:

I include if statements that handle conditions, such as JSON requests in the function add_book_to_wishlist

if not book_id:
    return jsonify({"error": "Missing book_id"}), 400

Iteration:

This is present in get_user_wishlist where the code loops over each item and appends it to books_in_wishlist

books_in_wishlist = []
for item in wishlist_items:
    book = Book.query.get(item.book_id)
    if book:
        books_in_wishlist.append({
            'id': item.id,
            'book_id': book.id,
            'title': book.title,
            'author': book.author,
            'status': item.status,
            'date_added': item.date_added.strftime('%Y-%m-%d'),
            'availability': item.availability
        })

Calls to procedure:

The function get_wishlist is called in the get_user_wishlist route. It retrieves all the books in their reading list by passing their _uid.

wishlist_items = get_wishlist(current_user._uid)

Output:

I have conditional output that is based off of selection. It adjusts the JSON output depending on the request:

if wishlist_item:
    return jsonify({"availability": wishlist_item.availability}), 200
else:
    return jsonify({"error": "Book not found in wishlist"}), 404

College Board MC:

Score: 61/67

Results by topic

Questions I got wrong:

My first MC:

Topics I had trouble with:

This time was mostly unit 3, but also 2 and 5. This means that I need to focus on:

2.3: Extracting Information from Data
3.7: Nested Conditionals
3.11: Binary Search
3.17: Algorithmic Efficiency
5.6: Safe Computing

Questions I missed in both MC’s:

algorithm efficiency and runtime
comparing code sets and algorithms

Things that I improved on:

NAND logic gates
completing code and using if statements
citizen science

Longest Questions:

The types of questions that took me the longest were mostly topic 3, which is algorithms and programming. Most of these took longer because they are more complex and require a lot of thinking, but I need to work on being more efficient with my time. A couple questions I got wrong and they took me a long time, which means I need to review them more. This topic is data selection, which is about constraints and limits of a certain program.

Quiz Corrections:

Question 15: Consider the two programs below. The figure presents two programs, labeled Program A and Program B, each with two blocks of code that consist of 4 lines. Throughout the second block of code in each program there are nested blocks of code, as follows.

Which of the following best compares the values displayed by programs A and B? My answer: Program A and program B display the same number of values, but the values differ. Correct answer: Program A and program B display identical values in the same order. Explanation: The two programs aren’t in the same order, but they both display the numbers from 1-10.

Question 21: Which of the following observations is most consistent with the information in the circle graph?

My answer: Over 75% of the files stored are at least 100 KB in size. Correct answer: Over 75% of the files stored are 10 MB in size or less. Explanation: The files at least 100 KB are only 59%, while the files up to 10 MB are 76%.

Question 30: In the following program, assume that the variable n has been initialized with an integer value. The figure presents 2 blocks of code that consist of 14 total lines. Throughout the code there are nested blocks of code. Which of the following is NOT a possible value displayed by the program?

My answer: too low Correct answer: out of range Explanation: Correct. The string ”out of range” could only be displayed if the condition n ≥ 1 was false. If the initial value of n is at least 0, then n will be incremented by 1, making n at least 1. Therefore the condition n ≥ 1 will be true and ”out of range” will not be displayed. If the initial value of n is negative, then n will be multiplied by -1, making n at least 1. Therefore the condition n ≥ 1 will be true and ”out of range” will not be displayed.

Question 40: Which of the following best explains how a certificate authority is used in protecting data?

My answer: A certificate authority certifies the safety of a particular Web site so that users know that it does not contain any viruses. Correct answer: A certificate authority verifies the authenticity of encryption keys used in secured communications. Explanation: Certificate authorities issue digital certificates that certify the ownership of public keys.

Question 47: The procedure BinarySearch (`numList`, `target`) correctly implements a binary search algorithm on the list of numbers `numList`. The procedure returns an index where `target` occurs in `numList`, or -1 if target does not occur in `numList`. Which of the following conditions must be met in order for the procedure to work as intended?

My answer: The list numList must not contain any duplicate values Correct answer: The values in numList must be in sorted order. Explanation: Correct. In order for a binary search on a list to work as intended, the list must be sorted.

Question 50: Consider the following algorithms. Each algorithm operates on a list containing n elements, where n is a very large integer.

. An algorithm that accesses each element in the list twice
An algorithm that accesses each element in the list n times
An algorithm that accesses only the first 10 elements in the list, regardless of the size of the list
Which of the algorithms run in reasonable time?

My answer: 3 only Correct answer: 1, 2, and 3 Explanation: for an algorithm to run in reasonable sum, it has to take a number of steps less than or equal to a polynomial function. 1 accesses elements 2n times, 2 accesses n^2 times, and 3 accesses 10 elements.

10th Point

Future Plans in Computer Science:

continue to improve my feature
Working on a new full-stack project with a database
learning how to use AWS to deploy programs

Self Reflection: Strengths and weaknesses

Strengths:

strong understanding of python code
experience in API’s and Postman
problem-solving

Weaknesses:

get a better understanding of deployment
javascript code
college board topics such as binary, computing safety, and networks
communicating and unity

Reflection on project:

Overall, my project works full-stack and has all the college board features as well as CRUD operations. There were many challenges, such as getting token to work and making the feature useful for the average user. There was also some challenges with integrating all of our group’s features to enhance cohesion.

Someone New:

Michelle Kuruvilla and I both helped each other review for the final, checking each other’s blogs and making sure we have all the requirements. We also practiced to make sure our presentations were good.
