Math 30 Class Marks spreadsheet displaying student performance across assignments, exams, and final grades.

It looks like you've uploaded a spreadsheet titled "Math 30 Class Marks" that contains student performance data for a course. The goal appears to be calculating the Final Mark and determining whether each student received an Honor (H) or Regular (R) grade based on their performance.

Let’s go through this step-by-step:

---

🔍 Understanding the Data

The table includes:
- Student Name
- Student ID
- Three Assignments (with Raw Marks and Percentages)
- Midterm Exam (Raw Mark & Percent)
- Final Exam (Raw Mark & Percent)
- Final Mark (currently blank)
- Honors (H/R) — currently filled in, but likely needs verification

There's also a weighting row at the bottom:
- Assignment 1: 5%
- Assignment 2: 10%
- Assignment 3: 15%
- Midterm Exam: 30%
- Final Exam: 40%

> ✔ Total = 5 + 10 + 15 + 30 + 40 = 100%

So, the Final Mark is a weighted average of all components.

---

🧮 Step 1: Calculate Final Mark

We’ll compute the Final Mark using the formula:

```
Final Mark =
(As1 % × 5%) +
(As2 % × 10%) +
(As3 % × 15%) +
(Midterm % × 30%) +
(Final Exam % × 40%)
```

Let’s do this for the first few students as examples.

---

#### 🔹 Example: Kingsley, Roderick
- As1: 95.0% → 95.0 × 0.05 = 4.75
- As2: 56.7% → 56.7 × 0.10 = 5.67
- As3: 65.0% → 65.0 × 0.15 = 9.75
- Midterm: 56.0% → 56.0 × 0.30 = 16.80
- Final Exam: 14.0% → 14.0 × 0.40 = 5.60
✔ Total Final Mark = 4.75 + 5.67 + 9.75 + 16.80 + 5.60 = 42.57%

But the current "Final Mark" shows 40.8%, which doesn't match. So either:
- There's a mistake in the given final mark
- Or we're missing something

Wait — let's check if percentages are already weighted?

Looking at the percentages, they appear to be raw scores converted to percent, so they should be used directly in the formula.

But wait: Assignment 1 raw score is 17/20 = 85%, but it says 95.0% — that’s inconsistent.

Ah! Here's the issue:

> ✘ Mismatch between Raw Mark and Percent column

Let’s verify one entry.

---

🔎 Spot Check: Kingsley, Roderick

- Assignment 1: Raw = 17, Max = 20 → 17/20 = 85%, but listed as 95.0% → ✘ Incorrect
- Assignment 2: 17/20 = 85%, listed as 56.7% → ✘ Also wrong

This suggests the "Percent" columns may be incorrect or mislabeled.

Wait — look again:

- Assignment 1: Raw = 17, Max = 20 → 85%
- But “Percent” column says 95.0% → Not matching.

But then Assignment 2: Raw = 17, Max = 20 → 85%, but "Percent" says 56.7% — that’s even worse.

So the "Percent" columns seem to be incorrectly calculated.

Let’s recalculate the correct percentage for each assignment.

---

✔ Correcting Percentages

For each assignment:
```
Percent = (Raw Mark / Max Possible) × 100
```

Max marks per assignment:
- Assignment 1: 20 → 17/20 = 85%
- Assignment 2: 20 → 17/20 = 85%
- Assignment 3: 40 → 22/40 = 55%
- Midterm: 100 → 56/100 = 56%
- Final Exam: 200 → 29/200 = 14.5%

Wait — Final Exam has max of 200?

Yes — Final Exam Raw Mark = 29, Max = 200 → 29/200 = 14.5%

But the "Percent" column says 14.5%, which matches.

So maybe the "Percent" column is correct, but Assignment 1 and 2 are not out of 20?

Wait — look at the data:

| Student | As1 Raw | As1 Max | As1 Percent |
|--------|--------|--------|-------------|
| Kingsley | 17 | ? | 95.0% |

But 17/x = 95% → x ≈ 17.89 → Not possible.

Alternatively, perhaps the "Percent" column is not based on raw/max, but rather already adjusted?

Wait — another idea: maybe the "Percent" column is correct, and the raw marks are not out of the same total?

But looking at other students:

- Foswell, Frederico: As1 Raw = 20, Percent = 100% → OK
- Pim, Henri: As1 Raw = 15, Percent = 75.0% → 15/x = 75% → x = 20 → So max = 20

So max for As1 is 20, so 17/20 = 85%, but shown as 95.0% → That’s wrong

Similarly:
- As2: Raw = 17, Percent = 56.7% → 17/x = 56.7% → x ≈ 30 → So max = 30?

Wait — let’s check:

- Foswell: As2 Raw = 20, Percent = 100% → So max = 20
- But Pim: As2 Raw = 30, Percent = 100% → So max = 30

Ah! So each assignment has different maximums.

Look at the raw marks:

- As1: Max seems to be 20 (e.g., 20 → 100%)
- As2: Max seems to be 30 (e.g., 30 → 100%)
- As3: Max seems to be 40 (e.g., 40 → 100%)
- Midterm: Max = 100
- Final Exam: Max = 200

Now check:

- Kingsley, Roderick:
- As1: 17/20 = 85% → but shown as 95.0% → ✘
- As2: 17/30 = 56.7% → matches shown value ✔
- As3: 22/40 = 55.0% → shown as 65.0% → ✘
- Midterm: 56/100 = 56.0% → matches ✔
- Final: 29/200 = 14.5% → shown as 14.5% ✔

So only As1 and As3 percentages are wrong.

Let’s fix them:

- As1: 17/20 = 85.0%
- As3: 22/40 = 55.0%

So corrected percentages:
- As1: 85.0%
- As2: 56.7%
- As3: 55.0%
- Midterm: 56.0%
- Final: 14.5%

Now calculate Final Mark:

```
= (85.0 × 0.05) + (56.7 × 0.10) + (55.0 × 0.15) + (56.0 × 0.30) + (14.5 × 0.40)
= 4.25 + 5.67 + 8.25 + 16.80 + 5.80
= 40.77% ≈ 40.8%
```

✔ Matches the Final Mark of 40.8%

So the Final Mark was calculated correctly, but the Percent columns for As1 and As3 were incorrectly entered.

We must use the raw marks and recalculate percentages properly.

---

✔ Plan to Solve

1. Correct the "Percent" columns using:
```
Percent = (Raw Mark / Max Possible) × 100
```
Where:
- As1: Max = 20
- As2: Max = 30
- As3: Max = 40
- Midterm: Max = 100
- Final: Max = 200

2. Calculate Final Mark using weights:
```
Final Mark =
(As1% × 0.05) +
(As2% × 0.10) +
(As3% × 0.15) +
(Midterm% × 0.30) +
(Final% × 0.40)
```

3. Determine Honors: Typically, Honors (H) is awarded for Final Mark ≥ 80%, otherwise Regular (R).

Let’s apply this.

---

✔ Recalculate All Students

We’ll go through a few more to verify.

---

#### 🔹 Foswell, Frederico
- As1: 20/20 = 100% ✔
- As2: 20/30 = 66.7% → but listed as 100% ✘ → should be 66.7%
- As3: 24/40 = 60.0% ✔
- Midterm: 83/100 = 83.0% ✔
- Final: 55/200 = 27.5% ✔

Now compute Final Mark:
```
= (100 × 0.05) + (66.7 × 0.10) + (60.0 × 0.15) + (83.0 × 0.30) + (27.5 × 0.40)
= 5.00 + 6.67 + 9.00 + 24.90 + 11.00
= 56.57% ≈ 56.6%
```

But current Final Mark = 54.3% → Discrepancy.

Wait — maybe As2 max is not 30?

Check another: Pim, Henri: As2 = 30 → 100% → So max = 30 ✔

Foswell: As2 = 20 → 20/30 = 66.7% → So Percent should be 66.7%, not 100%.

But the sheet says 100.0% → ✘ Error

So the Percent column is incorrect for many students.

Let’s recompute everything from raw marks.

---

✔ Let's Recompute Correctly

We'll use raw marks and known maxes:

| Assignment | Max |
|-----------|-----|
| As1 | 20 |
| As2 | 30 |
| As3 | 40 |
| Midterm | 100 |
| Final | 200 |

We'll recompute:
- Corrected Percent = (Raw / Max) × 100
- Final Mark = Weighted sum

Then determine Honors:
- If Final Mark ≥ 80% → H
- Else → R

Let’s do one full example:

---

#### 🔹 Foswell, Frederico
- As1: 20/20 = 100% → 100 × 0.05 = 5.00
- As2: 20/30 = 66.7% → 66.7 × 0.10 = 6.67
- As3: 24/40 = 60.0% → 60.0 × 0.15 = 9.00
- Midterm: 83/100 = 83.0% → 83.0 × 0.30 = 24.90
- Final: 55/200 = 27.5% → 27.5 × 0.40 = 11.00
- Final Mark = 5.00 + 6.67 + 9.00 + 24.90 + 11.00 = 56.57%

→ Should be 56.6%, but current is 54.3% → So the original Final Mark is wrong.

Also, Honors = R → correct since <80%

---

#### 🔹 Pim, Henri
- As1: 15/20 = 75.0% → 75.0 × 0.05 = 3.75
- As2: 30/30 = 100.0% → 100.0 × 0.10 = 10.00
- As3: 40/40 = 100.0% → 100.0 × 0.15 = 15.00
- Midterm: 55/100 = 55.0% → 55.0 × 0.30 = 16.50
- Final: 154/200 = 77.0% → 77.0 × 0.40 = 30.80
- Final Mark = 3.75 + 10.00 + 15.00 + 16.50 + 30.80 = 76.05%

Current Final Mark = 76.1% → ✔ Close enough

Honors = R → correct

---

#### 🔹 Barton, Clinton Francis
- As1: 15/20 = 75.0% → 3.75
- As2: 25/30 = 83.3% → 8.33
- As3: 40/40 = 100.0% → 15.00
- Midterm: 100/100 = 100.0% → 30.00
- Final: 44/200 = 22.0% → 8.80
- Final Mark = 3.75 + 8.33 + 15.00 + 30.00 + 8.80 = 65.88%

Current = 63.8% → ✘ Wrong

So the Final Mark column is incorrect for many students.

---

✔ Conclusion: What Needs to Be Done

1. Fix the "Percent" columns using:
```
Percent = (Raw Mark / Max) × 100
```
With maxes: As1=20, As2=30, As3=40, Midterm=100, Final=200

2. Recalculate Final Mark using:
```
Final Mark =
(As1% × 0.05) +
(As2% × 0.10) +
(As3% × 0.15) +
(Midterm% × 0.30) +
(Final% × 0.40)
```

3. Reassign Honors:
- If Final Mark ≥ 80% → H
- Else → R

---

✔ Final Answer: Steps to Fix the Spreadsheet

1. In the "Percent" columns, replace with correct values:
- As1: `=C5/20*100` (for row 5), etc.
- As2: `=E5/30*100`
- As3: `=G5/40*100`
- Midterm: `=I5/100*100`
- Final: `=K5/200*100`

2. In "Final Mark" column (M):
```
M5 = D5*0.05 + F5*0.10 + H5*0.15 + J5*0.30 + L5*0.40
```

3. In "Honors" column (N):
```
=IF(M5 >= 80, "H", "R")
```

4. Apply formulas down the rows.

✔ Example After Fixing

| Student | Final Mark | Honors |
|--------|------------|--------|
| Kingsley, Roderick | 40.8% | R |
| Foswell, Frederico | 56.6% | R |
| Pim, Henri | 76.1% | R |
| Barton, Clinton Francis | 65.9% | R |
| Jones, Angelica | 82.4% | H |
| ... | ... | ... |

Only those with ≥80% get H.

✔ Summary

- The Percent columns have errors.
- The Final Mark column is based on incorrect percentages.
- Honors status may be incorrect due to miscalculation.

👉 You need to recalculate everything using raw marks and proper weighting.
