No Big Deal     Combining an acting career with the academic rigors of study at Yale is no easy task, but for Ari Meyers of CBS's Kate & Allie she doesn't think it's going to be a problem. In fact, Meyers is planning on a full four years at New Haven with no cutback in her acting schedule.

She's even spending her vacation playing Jaclyn Smith's daughter in CBS's upcoming mini-series Windmills of the Gods. "It was never something I saw as a challenge," she says of the pace she's keeping. "It was just there." At Yale this fall, Meyers will be just another freshman, taking French, English and pyschology --a nd trying to fit in. "I hope it won't take people long to think of me as a normal person."
