Just like many of you, I’ve had a hard time passing Chemistry, that is until I found this guide. I recommend anyone that is taking Chemistry reads this since it makes the class look so easy now. They also use this in med school (hence the usage of the word “drugs”) however they are legal drugs (aka medicine).
