💁‍♀️ HI I'M MELISSA MARIBEL
I help students pass Chemistry and Organic Chemistry. I used to struggle with this subject, so when I finally graduated with a bachelor's degree in Chemistry, I became a tutor so that you wouldn't have to struggle like I did. I know that with the right help, YOU CAN LEARN ANYTHING!

Melissa tutored me in college algebra for a year and with her help I succeeded in achieving my first ever 4.0 GPA she helped make sense of concepts that I had trouble with. When I needed extra help on a concept we spent time going over it until I felt confident with it. With her help I had a very successful year and Melissa is very accommodating. She also always has more than one way to teach the same thing for those who learn in different ways. I would always recommend her to anyone that needs help in math or chemistry.

The night before my midterm and you totally saved me.

[aoyagworld]

wow, i am in SHOCK! i have been struggling with my chemistry class because i could not understand how to set up the problems, let alone figure out what to do with the numbers given! this is so underrated- it helped me so much, and now i feel confident that i will pass my exam tomorrow! i started the video with low confidence on this subject, but when i did the practice problems at the end (btw, nice dancin :D!), i got ALL OF THEM RIGHT!! thank you so much!

[leyhokanson]

I cannot thank you enough. You deliver the information so clearly and concisely! I am FINALLY understanding unit conversions and dimensional analysis thanks to the way you explain and break down the steps. Also, the practice questions at the end are greatly appreciated. Thank you! (P.S. I am digging the sweet dancing during the practice problems).

[lesliecaudillo]

I just found your channel ! And I’m taking chemistry again for a second time 😞 getting ahead by watching your vids thank you!

[RubiMercuri]

@3.29 why wouldn't it be 2 sig figs since there is the 72 there? are we always supposed to go with the given to determine our sig figs in dimensional analysis?

[Maryamhassan]

I LOVE LOVE LOVE you. you are such an amazing person for taking time out and making these videos to help students

[stephaniesibert]

Thank you very much. I was struggling understanding how to set up the problem and which factor to use and this completely helped me. I really really really really am soooo grateful that you did this video. You made it sooo much easier to understand.

[TheBookkeepersCottage]

What do you do if the conversion is not given to you? And you don't have it memorized? My teacher won't give us conversations on any of the tests

[Stewie]

I am so obsessed with all of your videos! Not me dancing along with you cause I got them all right LOL! Truly you are helping me so much! I currently have an A in my class but the exam is this Thursday in person... No notes. So here I am watching everything that I can to make my life a bit easier. OH she has a dosage problem on every test, so thank you!

[matthewhart]

Easy to understand, makes 100% sense. This lady is a genius.

[rhonerecords]

I have been watching your videos for the pass week, I'm a new subscriber, thank you so much for breaking it And by the way, nice dance moves, you go girl

[dayanpuentes]

I love your video, all videos, I couldn't do the problem. I felt like I was in an exam I understand but when I read the problem I do not know how to start. :(

[lunaali]

Hi Mrs. Maribel,
i would just like to say that you are an incredibly smart individual who not only has the brains to ace these concepts, but to also teach others in ways that none of my high school teachers can.
You are truly a blessing and I am so blessed to have discovered such a wonderful channel run by a wonderful teacher.
I better get back to watching the video:)
one of the many students you've helped,
Luna Ali.

[philorida]

Yay. I've been having problems with the textbook but you made it seem so logical.

[darkbeauty]

You are AWESOME. I subscribed because your videos are easy to understand and I finally get it! Thanks for including additional practice problems in your description box. I knew this couldn't be as hard as I was making it. Once you get it is kind of simple, but I still sometimes confuse myself. PRACTICE PRACTICE PRACTICE is helping me work these problems faster and get the correct answer! Thank you!!!!

I forgot to say I love that you dance during the practice problems. LOL

[Matt-ufdf]

Thank you Melissa. This is exactly what I needed to practice for my Hesi test.

[meryumsohail]

Thank you so much!!! Your videos really help me understand everything so much better! YOU'RE AMAZING!

[iknowitstoolate]

lol what do i do if it's a problem like this: "you go to a jeweler and choose a model ring you like that is made out of plastic. the plastic ring weighs 3.5632 g and the plastic has a density of 1.21 g/mL. How much would the gold for the same ring cost? (The density of gold is 19.3 g/cm^3, the price of gold is $1972/troy oz, and there are 31.105 grams per troy oz). Use correct significant figures."

SOS help me please assignment due in t-minus 2 hours
