In 1968, Merkel joined the Free German Youth (FDJ), the official communist youth movement sponsored by the ruling Marxist–Leninist Socialist Unity Party of Germany. Membership was nominally voluntary, but those who did not join found it difficult to gain admission to higher education. She did not participate in the secular coming of age ceremony Jugendweihe, however, which was common in East Germany. Instead, she was confirmed. During this time, she participated in several compulsory courses on Marxism-Leninism with her grades only being regarded as "sufficient". Merkel later said that "Life in the GDR was sometimes almost comfortable in a certain way, because there were some things one simply couldn't influence."
