Foods thawed in the microwave can be refrozen after heating it to this safe temperature. It is safe to reheat frozen leftovers without thawing, either in a saucepan or microwave (in the case of a soup or stew) or in the oven or microwave (for example, casseroles and combination meals).
Post-secondary education is a level of education that goes beyond a secondary level of education. This is usually any type of education after high school, which is considered secondary education. Post-secondary education is offered by colleges, universities, vocational schools and any other educational facilities that provide an academic degree or certificate.
Postsecondary education can lead to a career as an auto technician. Secondary education is high school, so postsecondary education is any schooling that follows graduation from high school or completion of high school equivalency. Community colleges, four-year colleges and universities are postsecondary schools, but other types of programs are also available, such as technical and trade schools.
