Algorithm to Calculate Average from 25 Exam Scores:
Step 1: Initialize a variable totalScore to 0, to keep track of the sum of all scores.
Step 2: Initialize a variable averageScore to 0, to store the calculated average.
Step 3: Accept input for 25 exam scores, one at a time.
Step 4: Add each inputted score to the totalScore.
Step 5: Calculate the average by dividing the totalScore by 25.
Step 6: Store the calculated average in the averageScore variable.
Step 7: Print the averageScore.
Pseudocode:
```
totalScore = 0
averageScore = 0
for i in range(25):
inputScore = acceptInput() // Input score from the user
totalScore = totalScore + inputScore
averageScore = totalScore / 25
print averageScore
```

Note: This is a simple algorithm that assumes the input will always be valid. You may need to modify it according to your specific requirements.
Certainly! Here's an algorithm to calculate the average from 25 exam scores:
1. Declare a variable `sum` and set it to 0.
2. Declare a variable `average` and set it to 0.
3. For `i` from 1 to 25, do steps 4 to 6.
4. Input the `score` for the exam.
5. Add the `score` to the `sum`.
6. Repeat step 3.
7. Divide the `sum` by 25 and assign the result to the `average`.
8. Print the `average`.
Here is the pseudocode representation of the algorithm:
```
sum := 0
average := 0
for i := 1 to 25 do
input score
sum := sum + score
end for
average := sum / 25
print average
```
And here is a flowchart representing the algorithm:

This algorithm will calculate the average of the 25 exam scores inputted by the user.
