We can and do teach concepts in many different ways for many different learning styles. We are not able to read minds, however. Be attentive, listen and be ready to ask specific questions to clarify any confusion you may be experiencing. Do homework the day it is assigned. Write down questions you have about lectures, or readings, or labs, so you will remember to ask them later.
Chemistry is all about communication.
Others must be able to read and understand your work. Work must be neat and easy to follow. Don't expect anyone to assume what you mean if your communication is unclear. Check the assignments page while you're ill. Make up all missed work the day you return.
