So the best time to ask for letters if you think you've done well on a rotation is right at the end of it right? So at the beginning of third year when you're asking for letters say at the end of your second rotation, are you still giving a CV or anything like that? Also people talk about how letters can be adjusted down the road, how does that work if say you got a letter in the first couple months 3rd year and you want to change it for your future specialty 10 months later. After they're done writing it where do they give it to, if its at beginning of 3rd year i'd think they're not sending it out anywhere, do they just give it to you and you make copies?
If anyone can help, I'd appreciate it. To 4th years, how many letters in total did you end up asking for during third year?
You need at least your CV for LORs in most cases and in all cases you need the ERAS cover letter.
These will not be available until late in the third year. In the event that a person offers to write an LOR early in third year, often you have to come back by with these two things to ask them.
As to the number, it depends on the programs. All the ones I applied to wanted three. So I asked 4 different people (there is always a writer that takes a while)
My 2 cents: do the best you can during your rotations. Do not ask for LORS until April/ May of third year at earliest.
If someone (in your desired field or not) OFFERS to write you an LOR duirng your rotations, make note of it so that when you get the cover letter and CV (and possibly PS) you can ask them properly.
After April/ May of third year and into your fourth you should have the above documents ready. Then at the end of a rotation (approx 3rd week of 4 week rotation or equivilent thereof) ask for the LOR from the chair, high ups ect. and expect to maybe have to talk to them a bit about your carreer plans ie academic vs private, region of the country, local vs moving ect.
You should have requested all LORs well before Sept 1 of Fourth year so that they can go up with the ERAS. My writers took an average of a month to write the letters. So you want to get the pertinent rotations in early M4 or have writers ready from third year rotations if this is not possible.
As to email: First option: schedule a time in the office with their secretary. They know what you are there for.
Second option: email to set up a time to talk to them. (attach CV and PS if possible) and bring the hard copy.
third choice: ask for LOR by email. I did this with one writer because I could not get a time to meet with her in her office as she was very busy and she had offered to write the letter previously. All other three I asked face to face. I think all of them were strong.
Hope this helps. I don't know about writing a letter 10 mos in advance and then tweaking it. I just asked them l8r and they remembered me and it worked out fine. I think this is a pretty common experience.
