Really? I wrote "Am putea face o carieră din asta!". It should've been accepted, because "am putea" is only used for first person plural and therefore it can be omitted. I almost failed a "Test Out" due to stupid stuff like this.
"ar" is "he/she/they" form.
am is for "we". (noi) am vrea sa bem - we would like to drink
ar - (EL/ EA/EI) ar vrea sa joace tenis - they would like to play tennis.
as- first person form. As vrea sa-mi omor soacra.
