Thank you for your ideas! To answer your question, I enjoyed what I have been learning throughout my 1st and 2nd year in college and wanted to go on to further education beyond college. Yes, I agree with you, this sounds superficial. But this is honestly what I thought, I really enjoyed science and being in lab. I just did not realize that grad school emphasizes research more than anything else. And as I said, I admit that I was immature on this. While I don't mean to not concede my mistake, I want to let you know that my school is a small college and I really did my best finding research opportunity after I realize its importance, but many professors are simply unavailable because there are SO few of them, and other professors do research in subjects I was not interested in, like pchem.
Unfortunately, my summer research advisor is no longer accepting students since he is preparing to go abroad. Besides, molecular biology is not something I'm really into, but I do believe some relevant experience is helpful. I will go back to the organic synthesis lab next semester. Although it'll be my last semester in college, this is better than nothing.
I want you to know that I have two poster presentations, one at my school and the other at another university. I also have one year of TA experience, do you think these will help? Thanks.
