To prepare for entering the work world, Darryl Laramore, supervisor of guidance for Montgomery County schools, advises students to:

* Learn to type: It can be a good entry into a profession. "If you can type 60 words per minute, you can show your creativity and work habits."

* Take as much math as possible. It's needed in the new high-technology jobs.

* Take speech. "Always an asset."

* Take journalism. "You learn to communicate succinctly." An engineer who can also speak and write well, says Laramore, will thrive.

* Get a part-time job. The evidence is that working students do at least as well if not better in studies than the nonemployed. (If you can't find a job, adds counselor Irene B. Ansher, then do volunteer work. It's a big plus on a beginner's re'sume'.)

* Role-play the job interview with parents.

* If you have a job dream, arrange (with parents' help, if necessary) to meet somebody in the profession. Laramore's daughter thought she wanted to be a lawyer--influenced by the Perry Mason TV show--but changed her mind after an office visit showed her the amount of divorce and accounting work.

"Rather than discourage fantasy," says Laramore, "parents should say, 'Let's explore it.'"
