Sekolah Agama Penjara Simpang Renggam is a place where I studied the science of Islam. I studied at this school from Grade 1 (7 years old) to Darjah Khas (13 years old). Darjah khas or known as Darjah Khas Agama (SDKA), is a system of Islamic religious studies that is only available in the state of Johor Darul Takzim which was formally introduced in 1923 again. Study at the Darjah Khas degree level is an advanced learning program at the Sekolah Agama Kerajaan Johor under the Institusi Pendidikan Agama Johor. The school session for students from Grade 1 to Grade 3 is in the morning while grades 4 to 6 are in the evening every Sunday to Thursday. For special grades, the school session is every Saturday, from 8am to 1pm.
