We started with level a for our first year homeschooling although ds is first grade due to the fact it was pretty new to us and a lot was not covered in kindergarten that right start did cover. We are starting level B next week and I noticed that it repeats a lot of what is in level a. Would it be a big deal if we skipped over the stuff he already knows from level a? Although we are taking the summer off we are gonna continue the level b through this time to get him caught up and moving into level c next school year.
