Before you ask your professors to write letters of recommendation for you, please follow these steps:
At least six weeks in advance of your deadline for submitting the letters, contact your professors in person or by e-mail to ask them if they are willing to write a letter. Provide the professor with specific information to help them recall you and your accomplishments. Include the following in your request:

The deadline for submitting the letter is (date), and if you are unable to provide a letter, please let me know by (one week from the date of this letter).
Thank you in advance for your time.
