## Solution

```Scheme
(define (remove fn list)
(let iter ((list list) (result '()))
(if (null? list)
(define (remove fn lst)
(let loop ((lst lst) (result '()))
(if (null? lst)
(reverse result)
(let ((item (car list)))
(if (fn item)
(iter (cdr list) result)
(iter (cdr list) (cons item result)))))))
(let ((item (car lst)))
(loop (cdr lst)
(if (fn item) result (cons item result)))))))
```
