about

AP Computer Science A is both a college-prep course for potential computer science majors and a foundation course for students planning to study in other technical fields such as engineering, physics, chemistry, and geology. The course emphasizes methodology, procedural abstraction, and in-depth study of algorithms, data structures, and data abstractions, as well as a detailed examination of a large case study program. Instruction includes preparation for the AP Computer Science A exam. In this course, students apply the programming tools they have learned to real-life examples on their own. Computer science is more than just programming; students who successfully complete the course will have an understanding of Java and the ability to adapt to any new programming language that they are taught in college.

September 27, 2024 | Quadratic Formula
Here is a possible solution to the Quadratic Equation task: 
 
 
  import java.util.*;

  public class Quadratic { 
  
    public static void main(String[] args) {
      
      //declare variables.
    double a, b, c, discriminant, root1, root2;
  
    Scanner kb = new Scanner(System.in);
  
    System.out.println("Enter the degree 2 coefficient of a quadratic equation:");
      a = kb.nextDouble();
  
    System.out.println("Enter the degree 1 coefficient of a quadratic equation:");
      b = kb.nextDouble();
  
    System.out.println("Enter the degree 0 coefficient of a quadratic equation:");
    c = kb.nextDouble();
  
    boolean openingup = (a > 0);
      System.out.println("It is " + openingup + " to suggest that the parabola opens up.");
    
    //we are assuming that the quadratic equation has a solution. 
      discriminant = b*b -4*a*c;
      root1 = (-b + Math.sqrt(discriminant))/(2*a);
      root2 = (-b - Math.sqrt(discriminant))/(2*a);
  
      System.out.println("The first root is: " + root1+".");
  
      System.out.println("The second root is: " + root2+".");
  
  
    } //end main
  }  //end class
September 22, 2024 | Weekly updates & Current grades
Hi everyone. I write to clarify a couple of things regarding grades and grading.
First, on myCushing under your progress tab you should be able to see your current grade for this course, which is a weighted average of the assessments we have written so far. While individual quiz scores will not be published on myCushing, the current grade will be updated approximately once week.
Second, when you read your weekly update, be sure to check the comments as well as the grade. Sometimes I add individual feedback based on recent performances or in-class observations.

As always, let me know if you have any questions.
