Based on this conversation, write an email to your friend (between 200-400 words), explaining to him why his studying habits are

Dear Sarah.

Firstly, I am very happy to know that you have decided to start a study schedule for your literature course in Colonial Latin America, I believe that you will gain great knowledge and that this will be very important for your academic career.

Because of the importance of this study, I decided to analyze your study methods and I fear that they are not efficient and that you will lose time and do not absorb the concepts really necessary for you.

Your study method is based on memorizing concepts and quotes and I believe that you should not rely on it to study, as our memory is relative and often does not last as long as necessary. So I decided to give you advice that I used during my study and that were extremely efficient.

My first advice is that you divide all the material that you have to study in small modules and establish an expert for the study of each one. Don't forget to put a rest time so that you don't get overwhelmed and start taking your readings automatically.

My second advice is that when you study each module, write summaries with the main parts and make mind maps that will be extremely necessary to make revisions.

My last and most important advice is that you make constant reviews and try to conceptualize and reason during this process, this will prevent you from memorizing, but introducing the concepts in your mind in order to understand them and not record them.

I am grateful that you will be successful if you follow these steps and I expect answers from you telling me the results.

Affectionately,

Caroline.
