Their policies do seem good but as you say i don't see how they are going to pay for them. They say they will pay for it with corporation tax. Not really what we want to be doing post Brexit. We need to attract companies here.
I don't really agree with the whole free tuition fee thing for 2 reasons:
1) Ive nearly paid mine off
2) I think you'll just end up with people going to university who don't want to be there just because they can't be arsed to get a job
Conservatives on the other hand don't seem to really have any policies.
