Im in my second year of University, working on a Microbiology major. For my MICB 202 coursemedical microbiology and immunologyinstead of a textbook, we have a note package written by PhD students. This book is filled with errors. Im not picky about grammar or spelling but the errors hinder comprehension. There are agreement mistakes in every sentence, and spelling mistakes every fifth word. Example: When a naïve CD4 T cells (known as T0 cells) has been activated by the interaction of TCR/MHC class II-peptide complex and binding of CD28/B7, exposure to different cytokines will influence wheter the T cell differentiates into a T1 or T2 cell. Every sentence is like this, and there are also numerous conflicting pieces of information. These are PhD students; they should know how to form a proper sentence. Sorry I just had to vent, Im having trouble understanding this as it is, and having to read and reread every sentence just to sift through the writing is getting on my nerves. Anybody else have experiences like this?
