Hi guys I am currently revising but I am having difficulty normalizing the project table below. I can achieve first normal form. but when I try to normalize to work out 2nf I get confused. The table does not come out clearly below so I have attaced a word document showing it and the question i am trying to revise.

on attempting to achieve 2NF i get the relations project and employee.
The project table contains
The Employee Table contains
Emp_Num(PK), Proj_Num(PK), Emp_Name, job_class, chg_hour and Hours.
I believe that the project table has been normalised to 2NF however I cannot say the same about Employee as it still contains a concatenated Primary Key. I do not know if I am right I need help to answer this question as something similar may come up in the exam. Please can some help me get this to 3NF and help explain how they got it to 3NF. I really want to know how to normalize but th I cannot find a simple guide.
I will be grateful for any help
