HiLine,
You seemed a bit worried by the whole proposition of calling (or emailing at
admissions@lafayette.edu) to check up on your application status. Admissions expects to receive calls from applicants daily asking those kinds of questions. Your question, thankfully, is an easy one to answer.
If you do not wish to call due to the cost, email is an alternative. Just don't expect a prompt response...admissions inboxes are full to the brim! It could take a day or even more to get a response because they are so busy evaluating applications.
I think it is worth incurring some cost to check up on the app, especially since it is so important to do so. When, and if, you decide to call, just tell them you are an applicant and that you wish to check on the status of your application (ask if they have all the required papers, for instance). You will be asked for your name, most likely, so that you can be looked up on the computer.
Good luck, and try not to lose your cool...I know the college admissions process can be stressful, but don't let it get to you!
