Can teens do ballet and karate?

I wasn't aware that the progress was saved. I have two level 6 ballet preteens and a level 6 karate preteen, and when I tried to start building up ballet skill for the level 6 karate, I'm sure I got some kind of warning telling me progress would be lost after the transition period (from one hobby to the other).

Only one hobby shows in the hobby ya for each preteen also. Do you have preteens who do both hobbies and have their progress from both saved?

"ya" was supposed to say "tab" - sorry.

I had the same question, but my search led me to the EA forums, where the EA rep, Nina, wrote:

"Yes, swapping hobbies will cause the progress for the other to be lost, similarly to careers for adults."

I haven't tried it, as I have one pre-teen climbing the ranks in Karate and I don't want him to lose his standing. My current goal is to have a pre-teen practice ballet on the barre at the Rec Center and luckily by tomorrow I will have a cake finished to grow up another toddler into a pre-teen and she will do ballet (although I wish I had planned ahead and swapped genders for these activites... but there was a Karate competition right after my first pre-teen was created).

I think it's lousy that they can't do both... it's also annoying that Adult Sims can't do more than one hobby or switch between careers. I seem to recall ages ago switching careers for one of my Sims for a goal, and being able to switch it back with no demotions, but that was many updates ago. I'm going to send a request to EA that they try to fix it so that skills in careers and hobbies don't get wiped out (maybe if enough of us do, they will work on it).

I know that with the Sims 1 and 2 there were all sorts of hidden attributes assigned to Sims - each Sim had a file with numbers listed for things like skills, personality, etc. (I downloaded a lot of cheat objects and read a lot about the creation of them, although making them was beyond my skills). iOS is such a disturbingly closed system.... I don't want to Jailbreak my phone (too scared of messing it up) and I haven't done any iOS development, but I would think that recording skill levels wouldn't be that hard to do or bulk up the program too much...

Here is the URL for the EA Forum I was talking about: http://forum.ea.com/eaforum/posts/list/30/8979001.page

If anyone has successfully switched a Pre-Teen Sim between hobbies without losing progress, please tell us - maybe the EA rep was wrong...

So if I age my preteen, I lose everything he knows about karate? No more ability to enter competition center on Karate day?
