Thoughts on the best format for submitting a Letter of Recommendation for a Senior to the Common App? I’m deciding whether to upload a nice looking/styled pdf or just a google doc (fonts are more limited and my ability to adjust things is limited) 
Also, should it use the traditional letter format that they taught in schools years and years ago (with return address, name date), or just a clean few paragraphs and my name on the bottom (less is more?). I’m leaning to a pdf with traditional “dear admissions office” then uploading that file. Do they prefer google doc links nowadays?
Does anyone have a preferred method they have used?
Thanks!!
