Each country has a unique higher educational system, so do not expect academics (lectures, assignments, exams, and other requirements) to operate the same as at SDSU.
For example, in some countries, your ultimate grade may depend only on a final exam and/or research paper. Your studies may also be more individualized or self-paced than at SDSU.
Be patient with yourself because you will be navigating a new academic culture and dealing with multiple distractions.
