There are warnings from universities that they might have fewer places to offer.
The coalition government's drive for a market in higher education could damage social mobility, universities say. Universities UK, representing university leaders, has voiced concerns about "unintended consequences".
In particular there are concerns that plans to expand places at institutions charging the lowest fees, and for students with AAB A-level grades, could limit choices for other students.
The government insists its plan means a "stronger focus" on social mobility.
