No, he isn't right. Some of the most intelligent and influential people in history have been Christians, and it's true even today.
Over the years, in fact, I've been privileged to meet a number of them, including many Christians who were outstanding scientists or scholars. Some told how they'd started out as agnostics, or even atheists, but as they studied the universe they realized it didn't make sense to say it had happened by chance. They came to echo the words of the psalmist: "The heavens declare the glory of God; the skies proclaim the work of his hands" (Psalm 19:1). Then, as they read the Bible, they realized not only that God made the universe, but also that He loves us and sent His Son into the world so we could come to know God personally.
Ask God to lead you to other Christians on your campus; you may be able to find information about Christian groups on campus bulletin boards. In addition, set aside time every day to be alone with God, through reading His Word, the Bible, and through prayer.
In addition, pray for your roommate, and for others you'll meet who've never thought seriously about Jesus. Pray, too, that you will be a witness for Christ by the way you live. And when questions arise, ask God to help you find answers; your Christian bookstore can suggest some books to help you. Remember Jesus' promise: "I am with you always, to the very end of the age" (Matthew 28:20).
