In a class of 25 students seven students each have two brothers or sisters four students each have one brother or sister three students each have zero brother or sister each have three brothers or sisters. The rest of the students each have four or sisters

In total, there are:

- 7 students with 2 siblings: 7*2 = 14 siblings
- 4 students with 1 sibling: 4*1 = 4 siblings
- 3 students with 0 siblings: 3*0 = 0 siblings
- 3 students with 3 siblings: 3*3 = 9 siblings
- The rest of the students each have 4 siblings: (25-7-4-3-3)*4 = 8 students with 4 siblings, totaling 8*4 = 32 siblings

Therefore, the total number of siblings in the class is:
14 + 4 + 0 + 9 + 32 = 59 siblings.
