***Grading System for IPAM, University of Sierra Leone***

 

🎓 Building a Java Grading System for IPAM, University of Sierra Leone

🔸 Intro: Why This Matters

At IPAM, grades aren’t just numbers—they’re defining moments. And honestly? Manually calculating grades is outdated. With a few lines of Java, we can flip that whole process into something faster, fairer, and future-ready. This blog post breaks down how to design a grading system tailored for IPAM using basic Java logic.

🔸 What the System Should Do

We’re building a grading assistant that takes raw scores, does the math, checks against grade bands, and gives meaningful feedback. Here’s what this little beast will handle:

• Takes inputs: assignments, midterm, final exam marks

• Applies correct weightings ( 25%, 5%, 70%)

• Calculates a weighted average

• Outputs a grade: A, B, C, D, F

• Drops a message that feels human (not robotic)

This isn't just numbers — it's building a system that speaks to students.

🔸 Grade Logic: What’s the Rulebook?

Let’s set the standards straight (customized for IPAM):

Average (%)	Letter Grade	Message
70–100	A	"Distinction – You crushed it!"
60–69	B	"Merit – Solid performance!"
50–59	C	"Pass – You got through!"
40–49	D	"Borderline – Close one!"
Below 40	F	"Fail – Don’t lose hope!"

for invalid inputs like negative marks or anything over 100. Message will be "IS NOT A VALID GRADE"

🔸 The Flow of the Program (Plain English)

Let’s ditch the code for now. Here’s the logic broken down like real life:

1. Prompt for Input: Ask the user to enter marks (e.g. Attendance= 5%, Midterm = 30%, Final = 100%)

2. Check Validity: Is everything between 0 and 100? If not, throw an error.

3. Weight the Marks: Multiply each mark by its percentage weight.

4. Add it All Up: Combine the weighted components.

5. Determine Grade: See which grade range the total fits into.

6. Display Feedback: Output the grade and a short message to the console or screen.

All done with a few conditions, a few checks, and clean design.

        }
