How do recommendations work?

<p>I plan to ask a few of teachers for recommendations very soon, but I still have a few questions regarding how everything works. Under each college I have listed, there's a section called 'Recommenders and FERPA' under 'Questions' where I can add my teachers - do I have to add each teacher's information to each college individually or is there some way I can add them all to some general master list then pick and choose which colleges they're assigned to later? Also it seems I need to invite my counselor to complete my school report and other forms - does this include a recommendation? (If not, when I invite my counselor online, does it go under teacher or other recommender?) Additionally, will my teachers see which colleges they're being assigned to and will I be able to interchange teachers? (Not that it really matters, just curious.) And what happens if a teacher submits a letter of rec/assigned a college but then I decide to delete the school from my list?</p>

<p>All of them will be sending recommendations online through the common application btw.</p>
