Most architecture schools will provide subjects / course that will teach you specific drawing conventions and the software to support the production of models, drawings, and reports. Often this will be based on high level principles rather than specific step by step instruction. Given the diversity and number of applications used by architects, it is almost an impossible task to teach and learn them all. Most universities will assume to varying degrees that students will learn to use commonly available production software in their own time. The good news is that there is an abundance of software available to students at low or no charge, in addition to a universe of self-paced tutorials online.
Deciding what software package to put your time into is the next tricky question. The school of architecture will have their own advice but will be reluctant to be categoric as to what software to learn. Often the software used by your first practice will guide your decision but, it is not worth getting too hung up on any one package as over time learning new software is normal and once you understand the conventions of one package they will translate to other similar packages.
