Well done, your English is good and I admire your qualification. However, you should use the article. A or a and the are known as articles. A and an are called indefinite artlcles as they do not indicate a specific noun; the is called the definite article because it does point to a specific noun. For example, a B.Sc is one of several but the B.Sc is the only one; a certificate is one of several but the certificate is the only one.
