What earned marks
Excellent structure and logic, you've got the initialisation, loop, addition, average calculation, and output all correct, with clear pseudocode syntax.

Add this, then re-mark: Selection outputs 'Pass' when average >= 50, 'Fail' otherwise

How it works
1
Your child answers an exam question
Typed, in their own words. Past-paper questions show the paper and question number.
2
It's marked against the mark scheme in seconds
They see their mark, what earned it and what they missed.
3
Wrong answers come back
A few days later they get another go, until it sticks.

Why this answer got 5/6
Example marked answer. A sample question written by us, not from a past paper, marked by ReviseWell.
An array Marks[1:5] already holds five test marks out of 100. Write pseudocode that calculates the average of the five marks, outputs the average, and then outputs "Pass" if the average is 50 or more, otherwise outputs "Fail".
Total <- 0
FOR i <- 1 TO 5
Total <- Total + Marks[i]
NEXT i
Average <- Total / 5
OUTPUT Average
IF Average > 50
THEN
OUTPUT "Pass"
ELSE
OUTPUT "Fail"

Good to know
- Built by a computer science teacher and used in real classes.
- The AI marks each answer against that question's mark scheme. Like any marker it can be wrong sometimes, so your child sees what the mark scheme wanted too.
- Your child needs to be 13 or over to sign up on their own. We never send them marketing emails.
- Paid plan: up to 40 AI-marked answers a day, cancel any time.
