@annoying_salman Depends entirely on how much effort the parents put in. Some people automatically assume home schooled kids aren't as smart, and plenty of homeschoolers are determined to prove them wrong.
I was homeschooled for most of my childhood, and kept up with my peers just fine. I had no difficulty re-entering the public school system in high school. My sister, despite being two years younger than me, was at the same grade level as me to keep lesson planning simple, and thus she was ahead of her peers - and still is in many ways.
The nice thing about homeschooling when done right is that you have the flexibility to adapt to individual learning styles and tailor the lessons to the student. As a kid who hated writing, for example, (dysgraphia made public school hell to me), lessons went much more smoothly when we discussed the concepts rather than writing about them. I could talk through math problems and memorize grammar like nobody's business. I credit that homeschooling approach with actually giving me a love of writing, since after I learned to type, the dysgraphia couldn't get in the way.
Basically if you can be adaptable, do your research, get good at planning lessons, and have enough free time to devote most of your day to being a private tutor for your kids, then yeah homeschooling can be the greatest gift you can give your kids. In addition to making learning easier and faster, it also gives your kids a lot more free time to actually play and be kids - to have a proper childhood. Only slight downside is that they don't get to socialize with other kids at school, so you have to find other ways to make sure they talk to other kids. My sister and I at least had friends at church to talk to.
