Also a special note for level 7: Internalist does not require any other degree, so do not waste time and money on normal medicine. Also, do not work in the fast food joint in this level - work in the hospital between dinner and 1 am to gather work exp. In order to save up for the internalist degree I would recommend taking an admin diploma first as it is cheap, quick and lets you save up for the internalist degree much faster.
I haven't noticed any... a little extra tip for knowlegde: a diploma gives about 5%, bachelor 10 and magister 15. So, for example in level 10 youcan take administration to magister as required and get 30%, but you need 45, so I would recommend accounting diploma and accounting or management bachelor.
The wealth % is actually the number of hundred $ you need in values - so just ignore the 1000 $ objective. But remember to spend money on items from the mall - it still counts fully towards your wealth and cannot be stolen. I think that you need more education than just the internalist degree, so you should start taking diploma classes(depends on how much you need, you may need a management bachelor too, or in the end, a management master) during daytime, and you can afterwards work from 8 or 9 till 1-ish to gather work experience.
Take an extra diploma. Even though it doesn't state it explicitly you will need it. Just take the cheapest one that is left - that should also be the one that is fastest to finish.
3 Also, make sure that you use your daytime hours (those where the school and most workplaces are open)wisely. That means: only talk to people after workhours, eat at 7 and 20(lunch can even be skipped if your green bar is full that day). This is of course not all that important if your career is at the burger place or the hospital, but it still means a lot for the education. At the later levels you may need more education than just the required degree. In that case, take an extra diploma. In level 10, you should have enough time to get the master of management after the required masters degree; this is just enough for the knowledge requirement.
Hope this helps
A few tips:
1 Guys are quickly befriended through bragging.
2 Your experience at one job is NOT lost when you switch jobs. This means that even though your goal workplace is closed at night, you can still work at the fastfood place and the hospital the rest of the time to make more money, and then return to your goal company the next morning. This will solve the issue of money, just remember to use it (money spent on mall items still show as wealth, but cannot be stolen)
Wow, it took me close to half a day to finish all 10 levels. It would indeed be nice to have saving option between levels. Actually a good game I think.
