What age was Paul as a student of gamaliel?

The Bible does not specify Paul's exact age when he was a student of Gamaliel, a revered Jewish teacher. However, it is generally believed that Paul, who was born Saul of Tarsus, would have been a young man, likely in his teens or early twenties, as it was common for Jewish boys to study under prominent rabbis during that age. This formative period played a significant role in shaping his later theological perspectives.
