Btec applied science Unit 2A , 2C, 2D

Hello ,
I am currently doing assignment 2A and 2C at the same time along with assignment 2D . I would genuinely appreciate it if someone who has actually achieved a distinction for each one or if you have achieved a distinction on one of them can you please help me as I am totally new to this course and I am totally confused with the structure . It would be a pleasure if you can help me or even show me your old assignment if you don’t mind . I can assure you that I won’t copy as it would be considered as plagiarism which I would not risk . Thank you will wait for responses xx
