Okay, so here is the deal. This is my third week in Gen Chem 1, and my first two labs so far were an 88 and a 74 out of 100 pts each. I do not know why I am getting this low of a grade. I do the work and I am a good student. I am taking Calculus III and Calculus Physics ATM, so I am a pretty good student. However, I just do not understand why my lab professor gave me low grades recently. I mean, I do the experiment exactly as it describes, write down the results and calculations, and answer both the pre and post lab questions. Despite doing everything right last experiment, I was given a 74. I am now pissed off that he would give me a low grade like that, especially since I need all A's so I can get into UC Berkeley, which is already super hard to get into. Aside from the complaining, what can I do to do better? I will say that this is my last chemistry class I need to take. I am only taking this because Computer Science Engineering and EE requires me to take General Chemistry 1 w/ lab. My strong suit is Physics and Math, mainly, and I study hard for all of my classes. However, lab is nothing like a regular class. I swear to God that I will never for the life of me understand how my other classmates all finish sooner than me in lab and get better grades. What the hell makes labs soo much different from lectures? I cannot afford another C grade, so this is really really important. If someone can help me out and give me hints that can pretty much get me straight A's for all future experiments, that would be awesome! Again, sorry for the rant, but you have no idea how infuriating this is to me.
