lets say i have an exam in 7 days from today, and i just received the PR course. Is it possible to learn to PR, apply the techniques and PR the material and have it all stored in your head so that confidently by the day of the exam all the information is in your head? is it safe to take the chance to learn and experiment with PR right before the exam? what i mean is are my chances of passing the exam greater if i learn to PR within 7 days or just study the conventional way? i dont know if i should risk the time to learn only to find out it doesnt work by the day of the exam
