In SoulSilver, for the second aptitude test, Baoba will call you a day after you have completed the last aptitude test.
Not TRUE i tried that once and it did not work so i played for 3 hours and he called me for the second test ( i think it can be on the same day)

Well, honey, after you strut your stuff and collect all eight Gym Badges in Pokemon SoulSilver, you better tighten those shoelaces and get ready for a showdown with the Elite Four. It's time to put on your big boy pants, train your Pokemon like there's no tomorrow, and show those Elite Four trainers who's boss. So, grab your potions, revives, and a whole lot of attitude, 'cause you're in for one heck of a challenge.
