Don't. Pick tools that will help you do they job you envision doing.
What to teach in school, this is an ongoing debate in our profession, I think the more successful programs keep students focused on design and theory the first few years. Later when students are more comfortable with designing they have them coordinate their designs with the other trades and evaluations as you describe:structural, mechanical, detailing, energy evaluation etc.
Using programs like Archicad where successful modeling follows how it is built requires you to think about how the building is goes together sooner than when we hand-drafted and worked in 2D and had all those poched areas that no one questioned and covered a multitude of sins and ignorance.
As to your original question, AC is as someone said, just a tool. You pick your tools so you can work smart to meet your goals. What do you want to be doing as an architect? How do you want to be practicing architecture in 5 , 10 or 25 years?
How you actually produce a building you will learn more on the job but the school should expose you to enough of the principles of the whole building and process that you won't be lost as Dwight was when he cantilevered his balconies
What kind of Architect you want to be?
One of the best pieces of advice I received was to spend a summer working in a small office. I saw and worked on all aspects of many projects. Back then small offices tended to equate to smaller projects. Now, with Archicad and the like small firms can compete for large projects.
Another summer I worked for a firm of over a hundred. Very different work and work experience. Large projects you work on for a long time. Seemed like forever. Some like the sameness for years; but not me. This is sounding like Goldilocks and the three bears. I then worked in medium sized firms and loved the variety of project types and sizes. For me this was right.
Get as many types of experiences as you can.
Take advantage of everything you can at school that you won't get once working. School should give you a foundation in the profession, but if they focus too much or too early on nuts and bolts of building then you won't be able to freely learn design basics.
And have fun.
