Dear Melissa - As a current college student with ADHD, It was extremely difficult to grasp Chemistry at such a fast pace. I failed, having to retake the course again, and fell into a very bad headspace. But when I discovered your videos, I could finally understand each concept.. all for free! (This is too good to be true)! I can't thank you enough. Your videos motivate me during the most challenging times, and I am finally excited to learn again. Thank you so much, from the bottom of my heart. Never stop teaching! Thank you, always ♥!

Thank you Melissa your videos are helpful may God bless you abundantly.

Starting chemistry soon, this is a great way to get back into it before school starts. Thank you for this series, you’re the best!!❤️

Just started my sophomore yr of college and haven't taken chem since my sophomore yr of high school! Definitely a LIFESAVER!!!!

This is year two of watching your videos ...still! And I am so absolutely grateful that you have helped spread your knowledge. I can guarantee I would not have been able to work my way to an A last Spring semester without your help. So thank you, thank you, thank you! The hard work you put into every video, checklist, practice problem set and notes are very much appreciated! You are amazing!

im so glad i found your channel! I just started intro to chemistry and i haven't taken chemistry since wow high school!!! but love your videos so far! I was taking notes, but i was wondering if there is any notes that you may have already uploaded, so I can print and highlight.

sooooo easy to understand, was having trouble in class to do sig figs, but now I am really understanding it! Thanks so much!

this is amazing. I can tell I'm going to review with this channel a lot. Thank you!! Really love the practice problems so I don't forget right after the video. You're awesome!

My Chem teacher uses your videos in class all the time and they are SO helpful! I watch your other ones just because of the chill vibe and you make everything so simple. Thanks for making these videos, you're an awesome person. 😊❤

About to start chemistry after YEARS. And I was not good at math because I never tried. Love the way you explain it it makes sense. Thank you for posting.

Hey Melissa Loving ur chem vdos Keep it up 🤟🤟❤️

I haven't taken chemistry since high school, 37 years ago! (I know, they only had answering machine and beepers back then). Put my big girl panties on and taking chemistry at my local community college. You can imagine how rusty my math is! Love how you break things down so plainly. And, I adore your brand, friendly color scheme. Where can we find the answers to your Chemistry Checklist? I completed the problems but don't know if they are right.

I needed this so bad! I am hoping to go to grad school so back to Chemistry ! This brings back anxiety from grad school but unlike then now there are places to get clarification Thank You!

Oh my I thank God for you, Melissa! 😭💖

Thanks a lot maam for understanding about our feelings and making so much enthusiast video loved ur video keep on making these videos maam 😘💫

OMG! THANK YOU! GOD BLESS YOU!

You, the best 💖.. Thank you so much ❤😊. A very perfect explanations evertime.

I've heard that in chemistry if the digit to the right of the last number you want to keep is a five you are supposed to round up if it's odd and leave it alone if it's even. For example, if I was told to round 2.5 to 1 sig fig, it would be 2, not 3 because 2 is even. Is that true?

In actual order of operations it doesn't matter if you do Multiplication first or division first, You should still come to the same answer. This also applies to Addition and subtraction. which is why some people say BEDMAS, while others say PEMDAS. It's the same result. You can flip the order around and still get the same outcome, but this only applies to MD or DM being in the middle and AS or SA being last. What I'm trying to say about the MD and AS is that those don't have to go from left to right although we are very consistently reminded in this video that it must go left to right when really it doesn't. it's Brackets, Exponents, M or D (If M was chosen you do D next and vise versa), A or S (If A was chosen you do S next and vise versa).

Heaven sent thanks sooo much!!!

underrated u will conquer the world one day

THANK YOU!!!!!

Awesome🎉

OK like I love you

So pemdas works in every situation except every situation? Great lol.

Are these Sig Fig rules just something you memorize? They don’t seem logical to me.

Unfortunately yes these are rules you memorize.

No wonder I've been getting it all wrong....
