Hey!

As you can imagine everyone's learning journey is different and whether you'll pass an exam or not heavily depends on a variety of factors. However, personally I would be very positive that by devoting a time period of 50days/8hours per day is a massive amount of study time and you should have the maximum amount of chances to pass the exam. Don't forget to build comprehensive notes along the way as this is an openbook exam where you are allowed to use your own notes.

Good luck!
