Hi Ameeramz,
Have you contacted your lecturers and asked for some support and let them know your struggling? When I struggled with certain aspects of my course, i found it really helpful to sit down with a lecturer and go through the work, that i was struggling with. Please don't stress to much about your degree classification right now, just focus on passing this module first. I personally didn't find that my second year grades affected my overall classification grade, all that much. I know YSJ have two ways of calculating the end classification grade, depending whether you did better in 2nd or 3rd year. Maybe speak to a lecturer and find out, how they do this, as it could help with some of the stresses around this.
Good Luck!
