Write a letter to your sister and give her some tips about how to score well in exams.? can anyone answer it right now plz ​

Dear (Sister's name),
Hope this letter finds you in the best of health and spirits. It has been a long time since I have received a letter from your end.How are your studies going on? Sister, today I am going to write a letter to you advising you to work hard for your upcoming examination.
Since you have only a week to prepare yourself for examination you must worker harder than usual.You must have all your determination and resolution to bring laurels by performing well in your exam.I suggest you to study whatever your exam schedule has given.Give a little more effort and importance towards Maths and Physics as they are both conceptual subject. These days will become your best days as you will prepare for yourself.Don't take too much of tuition unless it is very important .Don't take too much of stress on yourself as you can take breaks for sometime.You can listen to music, meditate your mind so as to refresh your brain . You have to eat healthy food till your examination ends as it is equally important to stay fit, to have strong mind and to have a healthy body in order to give exams.
Hope by giving some suggestions to you will prove a beneficiary factor to you. I believe that you will perform well in this upcoming examination as you are already a diligent student.Please convey my regards to my mom and my dad and my best wishes to you and the rest of our family.
Thanking You,
Yours lovingly
