Customized curriculum is a huge advantage to homeschooling. Homeschoolers are not limited to curriculum at a set grade level. Instead, they are able to determine the exact level to meet their skills and abilities and begin there. This means that some homeschoolers will be working at a fifth-grade level in math, a sixth-grade level in English and still another level for other subjects. This approach gives students the advantage of mastering necessary concepts before moving on and progressing quickly in those subjects where he or she is most successful.
