I tweaked my strategy after my practice file by changing one of my Sims traits to loner and making the house 1 room instead of 4. In my scoring file, I made a 5X5 "studio" for my Sim whose aspiration and traits were: computer whiz, genius, geek and loner --- eventually, she was able to buy night owl from the rewards store. Because she was a loner, she enjoyed staying at home on the asphalt abodes lot, and since her social need filled more slowly, she didn't get sad because of not being social. By having her live in such a small space, I was able to purchase the §10,000 unbreakable computer --- so I didn't have to waste time calling the repair man. She also had a single bed, camping cooler, and a full bathroom. Her home only had a back door with a telescope very close to it to prevent stranger danger. That part of Newcrest only has a few joggers, etc. go by the lot. So, she maxed the video gaming and logic skills, plus garnered the achievements of all-nighter, introvert and older and wiser. She did get to about level 3 of the programming skill.
