<p>Thanks to whoever it was who mentioned what a great educational website this is.</p>
<p>My son has been struggling in physics, and this site has been such a boon. His physics teacher, whom I queried as to whether this site was giving correct information, stated that it looked okay to him. </p>
<p>Thanks again!</p>
<p>A grateful mom</p>
<p>Wow, this website seems pretty legit I’ll definitely be using it this year :)</p>
<p>I LOVE THIS WEBSITE, it has helped me through SO much.</p>
<p>Thank you for sharing!</p>
<p>I wasn’t aware of this website and like your son I’ve been recently struggling in physics too. I hope this will help.</p>

<p>Sal Khan almost certainly knows more physics then a high school physics teacher does.</p>
<p>He’s absolutely amazing! I never really looked into his physics videos, but his chem and calc ones really do help.</p>
<p>This website is how I have an A- in AP Calc AB. I love it!</p>
<p>I didn’t think the Calc ones were that good…</p>
<p>I’m pretty sure some of his calc ones were made awhile ago, the quality has definitely increased since then. Regardless, they have helped me a lot.</p>
<p>How did people not know about this website? This guy taught all my classes last year.</p>
<p>Agree with what @dfree124, some of the Calc ones are pretty old, and therefore have a slightly lower quality (video quality wise). He did redo some in HD though, and they look really nice!</p>
<p>Overall, the videos are extremely helpful, and I would recommend watching them.</p>
