Carboxylic acid derivatives include the carboxylates, amides, and esters. Also anhydrides, acyl halides, thioesters and acyl phosphates. Of the latter group, anhydrides and acyl halides don't appear in biochemistry, so while they are important for general organic chemistry, the new MCAT in not be so interested in them. However, thioesters and acyl phosphates do figure prominently in biochemistry. In fact, having a high free energy, the status of thioesters and acyl phosphates as the prototypical activated acyl compounds in biochemistry makes them among the most important types of organic molecules to understand.
