Does HSC mean class tenth or 12th matriculation?

Higher Secondary Certificate (HSC) typically refers to the certificate awarded upon completion of senior secondary education, which is usually the 12th grade in most countries. In some systems, the 12th grade may be referred to as "class 12th" or "Grade 12." Depending on the specific education system, HSC can correspond to different stages of education; therefore, it's always best to verify the exact level it represents based on the context or the specific education system in question.
