Yes, the ONLY way the Gemora says to get Olam Haboah for a man OR woman is Torah. And the only method the Gemora lists – the ONLY one – is: “By sending their children off to the Bais Hamedrash, and by waiting for their husbands to come home forom the Bais Hamedrash.”
That, the Gemora says, is THE way for you to get Olam Haboah.
