TUITION top-up fees could prevent Yorkshire teenagers from taking up university places, according to research by leading educational publisher Letts Educational.
Almost 60% of GCSE students said the new fees would make them think twice about going to university in the survey, carried out on revision aid website letts challenge.co.uk.
Just over a third claimed the fees wouldn't affect their decision, with 7% unsure.
The results come as universities face disruption over the next few weeks with action planned by the National Union of Students over the fees.
Letts Educational's Peter Stafford said: "The introduction of top-up fees could well see teenagers taking up different options to the traditional route of furthering their education through university.
"It risks students being deterred from university solely due to the cost.
"The results of our survey seem to show that this is a real concern for students."
