Getting the Porcelain Tower is a must in pretty much every deity game, no matter what the ultimate goal is. And the easiest way to get that is to build the Haga Sophia, spawn a great engineer, wait for education and rush build the tower. The reason this works is that the AI doesn't like to build the HS for some reason.
Now, if the National College is delayed in the opening game Education will also be delayed, and there's a risk that it won't be discovered before an AI builds the PT. And there are many good reasons for delaying the NC; going for the Hanging Gardens, Early cultural wonders, more cities or some early military rush.
I've had quite a few attempts where I tried to do too much in the early game and lost out on the PT. But after a while I noticed that I always failed because I didn't get Education fast enough, and never because I didn't build the HS fast enough. After noticing this, I've changed my research order to get Civil Service before Theology.
Except for the slightly increased risk of not getting the HS, researching Civil Service first is stricly better in every way. At least as long as happiness is positive.
1. The extra food from Civil Service will help the Capital Grow faster, which means the Haga Sophia can be built in fewer turns when Theology hits. In some cases the extra growth might even make production focus unnecessary for building the HS. After getting more (over?)confident that the AI won't build the HS, I now try to balance the production so that HS is completed on the same turn as education.
2. The extra food will also increase science from population. I haven't done the math on this one, but my gut feeling is that this can shave off at least a turn on Education compared to the other way around.
3. The pikeman is available earlier. That's a pretty situational benefit, but can help on defense sometimes.
4. The extra food for 15(?) turns means you will have a larger city, with more of everything after the PT is built. (Yes, that's kinda the same point as 1 and 2)
Another tactic can be to stay in production focus and try to get the chichen Itza, or some other early wonder that is still unbuilt. The most important thing here is maybe not the order of the techs, but the insight that the Haga Sohpia does not need to be rushed; it is fine to complete it in the same turn as education and optimize for other things.
There will always be a few (10?) turns between the national college and Civil service. Focusing on food in these turns would be a waste unless the city is really close to getting a new citizen. It is better to stagnate and build something here. Anything. If a settler is needed this is probably the best time window to get it.
Disclaimer: I have played a handful of games in this manner, and have yet to lose out on the HS. But it can of course have been a lucky streak. I also have the Wonders of the Ancient World pack, which may or may not alter the timing of the HS.
