We (former ADCOM member) take letters of recommendation very seriously. But we EXPECT them to be excellent! So, in one sense, in most cases a good LOR doesn't really help you, since naturally it will be good. In rare cases someone who knows you well and can articulate well your positive points and realistically and honestly diminish your negative points can genuinely help. On the other hand, a weak LOR together with a borderline GPA and MCAT can kill the application.

We will look at all four years of grades, but if there has been an improvement in the later years we will certainly notice it, with favor.

Currently, those grades mentioned with a 28 MCAT have a realistic chance of success.

We have several students who practiced as nurses before admission to AUC and were usually very successfull, especially in their later studies.

"I have not yet wrote my MCAT..." Unless English is a second language to you, you must be careful in your essay to use appropriate grammar and spell correctly. Your ability to maintain attention to detail over the long run is being evaluated together with the essay content.

Good luck.
