100 dias cumpleaños
Yes!!!!! I reached my 100 days cumpleanos. Just passed the most difficult lesson (Past Verbs) so far and now going smoothly through the present verb number 3 lesson. With the statement from Duolingo that I can read 59% of the Spanish internet, who would have thought that 100 days back.
Feeling proud and many thanks to Duolingo and of course everyone in the feedback discussion fora. :D
Just an advice: in that case you shouldn't write "cumpleaños", because that word means "anniversary of a birth" or "birthday" and you've only reached 100 days.
