Depends if you're going to say those skill levels are definitely /1 not /0 - because it is obviously much easier to acquire the latter. It's an issue of definition - what someone considers skill level 1 to be. If a 4 years basic training programme gives you five skill level 0 and 1 skill level 1, it suggests skill/0 is rather more than it seems to be considered elsewhere in the rules.
Okay...... time to acquire.
The best result you can get is (normally) 1 skill rank per term from your service/specialist skills, and 1 skill rank from an event, plus one every other term (ish) from promotions. In addition, you've got about 3 more skill ranks from character connections and 2 from the party skill package.
Id say 4-5 terms is probably a fair guess from the rules.
