I've done part of it (not the value of the questions, but including the
answers in the source). For an exam I gave last year on the OCaml
language, I put the solution for the code questions in the source, and
use it to generate the expected type of the function. (This way I could
also make sure I was not asking to code something too difficult.)
Here is part of the exam (sorry, it's in French, but it should give you
the general idea). I also include the beginning of the file since I've
found that more examples about how to set things up always helps.
There are two kinds of code blocks below: those with results "silent"
are just used to add some things to the session (OCaml works by default
with a session in org), those with results "verbatim" export the
result of evaluating of the source, which is what the toplevel answers
(i.e., the type).

* Arbres binaires annotés
Les fonctions demandées dans les questions suivantes peuvent dépendre les unes
des autres. Vous pouvez toujours utiliser les fonctions que vous ne savez pas
définir.
** Définition du type
#+BEGIN_question
Définir un type polymorphe ~('a,'b) tree~ représentant un arbre annoté. Les
constructeurs de ce type seront l'arbre vide ~Emp~ contenant une annotation de type
~('a)~, une feuille ~Leaf~ contenant une annotation de type ~('a)~ et une valeur
de type ~('b)~, et un nœud ~Node~ contenant une annotation de type ~('a)~, un
sous-arbre gauche et un sous-arbre droit.
#+END_question
#+name: treetype
#+BEGIN_SRC ocaml :results silent :exports results
type ('a,'b) tree =
| Emp of 'a
| Leaf of 'a * 'b
| Node of 'a * ('a,'b) tree * ('a,'b) tree
#+END_SRC
Dans les questions suivantes, il faudra maintenir l'invariant suivant: un arbre
est soit vide (constructeur ~Emp~), soit il ne contient pas de sous-arbre vide
(tous les sous-arbres sont soit ~Leaf~ soit ~Node~).
#+BEGIN_question
Écrire une fonction ~tag~ prenant un arbre et renvoyant son annotation.
#+END_question
#+name: tag
#+BEGIN_SRC ocaml :results code verbatim :exports results
let tag = function
| Emp a -> a
| Leaf (a,_) -> a
| Node (a,_,_) -> a
#+END_SRC
