I just submitted my primary yesterday and I am having issues with my LORs. My one orgo teacher has gone MIA since I asked her in April and I followed up many times after and she has not replied. My other science teacher wrote the letter, but forgot to sign it at the bottom and she is not replying to her emails as well. I do have one non science letter, thankfully. So my plan is to essentially go see them once school starts again (late aug) and have them complete the letters. Is it possible to submit my secondary without the LORs in and then have them submitted later in August?
