Unfortunately, Lectora controls the randomization and you cannot tell it to selectively not pick certain questions. However, you could use a 'reset test' action on the fail page to clear all of the student's previous answers and it will also re-randomize the test. If you have a very large question pool, the chances the student will have the same questions will be extremely low.Unfortunately, Lectora controls the randomization and you cannot tell it to selectively not pick certain questions.
