You can find a great - and free - info on tuition free universities at tuitionfreecolleges.mtnhome.org. There's a list of several hundred tuition free universities, colleges, schools, etc in Sweden, Norway, Finland and even in the USA!

It helps to apply early to the tuition free colleges in Sweden as there is some talk of late of trying to make foreign students pay. Also be aware of people who want you to pay high amounts of money getting you a visa. There's a small but vibrant Nigerian community in Sweden and more and more African professionals are going to the country. Hope this is useful info to you! Good luck.
