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.
Secondary education is divided into basic secondary education and pre-university secondary education. At the end of basic secondary education, pupils can choose between pre-university education and technical and professional education. Those who complete pre-university education are awarded the Bachillerato. Technical training leads to two levels of qualification-skilled worker and middle-level technician.
