Australia- is the subject most- is the predicate
Computer Science and Engineering is an engineering discipline, which focuses on the subject "Computers", from hardware to software, and is taught across most universities in Asia. Some of the most prominent ones are the Indian Institute of Technologies. Most universities offer B.Tech (Computer Science and Engineering) as bachelor degree and M.Tech(Computer Science and Engineering) as post graduate degree.Candidates enrolled for the discipline are required to study basics of all core engineering along with papers from the main subject. Engineering Mathematics is also given prime importance.
Civil engineering requires a high level of mathamatics and also physics so these subjusts would be a very good choice. If only one subject can be chosen, then maths is probably the most important.
Ashford University and ITT Tech may offer the most valuable online engineering degrees. Lehigh Unversity also offers a respected master's degree in the subject.
Most audio engineering programs have specialties in studio engineering, systems engineering, mixing engineering, and recording engineering. A lot of schools specialize in live sound engineering and audio post engineering.

Gordon M. Sessions has written: 'Getting the most from city streets' -- subject(s): Traffic engineering
Because they're taught 1 subject which they major in, focusing more so on that topic than others.
Most likely the country(people) of Australia loves Australia the most.
the most preferred course after mechanical engineering is doing m.tech
