It's a relatively simple task.
I'll knock out an abbreviated one now.
To Whom It May Concern:
This letter is written at the request of Mr. Robert So-So and is in strong support of his application for admission to your medical school. As Robert's professor for two classes and research advisor for almost 2 years, I consistently found him to be skilled, enthusiastic and conscientious
He is extremely bright, articulate and personable. He is unusual in both his seriousness of purpose and in his intellectual ability. As a research assistant, I was impressed by his blah, blah and unceasing commitment to blah, blah.
In the two classes that he took with me, he consistently performed within the top 2 or 3 percent of the class. And he earned an A in both classes, but what made him stand out was his willingness to always offer insight and meaningful contributions to our class discussions.
He also exhibits exceptional interpersonal skills when dealing with other students and faculty members.
Beyond the context of work, he?s a great person. I have also gotten to know him as a friend and in spite of all his great talents and accomplishments, he remains humble and sincere. Simply stated, he is someone you want to know?a pleasant soul.
I am confident that Robert So-So will become a successful medical student; but more importantly, I am confident that he will be an incredible physcian. I would welcome him into the profession and only hope to have someone like him as my family doctgor. As such, I highly recommend her to you with no reservations.
If I can be of any further assistance to you in consideration of Robert's application, please do not hesitate to contact me.
Sincerely Yours,

Okay, so that is pretty basic, but it has everything that you'd need. You want the level of endorsement like with or withour reservations, you want the number of years and context, you want an appraisal of your intellectual, social, and emotional maturity. Don't offer any criticism of yourself. It's magnified in recommendations, because recommendations are always inflated bull, so that focus on that, because most of us get these great recommendations that make us appear like the best student ever. It's a game.
Good luck
