Hi, everyone. You can call me Jason. It’s a simple job but one that requires patience and time. I need a very careful and patient person to be competent for this job. Please complete a pre-lab analysis report according to the guidelines I uploaded. The first is the “instruction of this labâ€œ, and the next are pre-lab diagram requirements, lab requirements, some notes, and the pre-lab sample. Based on these files, please browse and complete the pre-lab carefully. More importantly, if you have something you uncertain or do not understand, please consult with me â€œin time”. In this way, the quality of the final work can be better guaranteed. Glad to cooperate with you.
