The only labs that our children had were the **kitchen table**...yet....
My three homeschoolers were accepted to college at the ages of 13, 12, and 13. All finished all general college courses and Calculus III before the age 15. The two younger earned B.S. degrees in mathematics by the age of 18. The older of these two earned a masters in math by the age of 20. The oldest homeschooler recently graduated with a masters in accounting but chose to combine part-time college with work, travel, and reaching the national and international levels in his sport. He represented the U.S. in many countries around the world. Due to his work experiences he is completely fluent in Russian.
And your children are the exception not the rule. Home schooled children do really well no doubt about it. I am not ( and in my posts you cannot find) against home schooling.
I know many home schooled children. Not all excel as yours did.
