For an official open day - Y12/L6. For having a look at universities at other times (and their surrounding times) - Y10 onwards. We've parked at several universities on our way back from family holidays so that DSs can have a qaick look round.
Thanks. Have tried suggesting that a weekend away be booked to somewhere we can look at unis. Not sure what course we'll be looking at yet as they seem to be changing their mind (sighs). Perhaps it had better be one where they can change course easily.
