I sat my BA7 exam in July and was really worried about remembering everything for the exam. I study with Training Link as well and continually practiced the questions in the study books and on the paper mock without my notes to see what I could and couldn't remember. I then sat the Training Link and ICB mocks without any notes to hand and that gave me confidence for the exam.
One thing I found really helpful was to have the key information on small notecards which I practically carried everywhere with me and my husband continually tested me on.
Good luck for the exam
