i have a big dilemma right now, so i am preparing my application to reapply and asking my LOR writers to write new updated letters. I am trying to fix whatever mistake I made last cycle and I believe I am doing quite well on that track but stumbled upon something that I need suggestions. So my LOR from the lab I have been working the longest I believe is mediocre and I believe like many of you have noted taht it will raise a flag, or make a very good application look not as good. I have been putting a lot more hours recently in his lab b/c course load has been gettin more light and I have more time to spend on my projects. I will most likely continue to research in his lab half time during the year taht i re-apply but will not be there this summer since i have an obligated job that i took on for the summer period. i was wondering if i should ask him to write me a LOR now or wait till I come back in september (but I won't be doing nething over the summer in the lab). Should I explain my situation to him asking him to write a longer LOR (I never read his LOR but I saw it was only 1 page long when he printed it out before sealing it) and tell him taht I really need a strong LOR from him? I need some advice here. Thank you.
