Okay, that helps alot. Thanks. Now, I'm at level 2 at everything except fertility and med. I'm trying not to upgrade anything until I get enough points to buy stage 3 science, since that will help me gain points faster. I have pop of 15, 59,000 points and food stays around 2000. I have 6 master scientists, but one is nursing and right now I have all but 2 working on other skills; before I quit for the night I'll put half on research and half on food. Would you say I'm using a good strategy?
