I am reapplying to pharmacy school and took organic chemistry once and received a D. The second time round I took it with the same professor, I believe I am getting a B. My Professor is someone who is willing to write a stellar letter of recommendation if needed. My question is, will it look bad to admissions? Would I be better off asking my professor from Biology 101 to write me a letter? I received a B in her class and have taken it once.
