To point 1 and 2...brilliant...you yourself say the Reading is of NO value...you will work hard and see it through..GOOD!
point 3...can't believe in myself....Bul****it....with such a thought in your brain you will go through life with a looser instinct...BELIEVE IN YOURSELF...because if you don't...Other will neither.
She told you that you will not pass.....then you have 2 choices...Give up....or FIGHT!!!
To say that you need a Reading to get your fighting spirit up in order to make it...well ok....my Reading advice is YOU MAKE IT..........IF YOU DO A BIG EFFORT!
Instead of giving up...make her a fool....show her that she is wrong...let it burn in your brain...be MAD...use it as fuel for your success.....not as reason to quit.
Life is all about challenges...to show that you manage...to have focus...I have been in your place...I have failed...I become mad...I did everything one more time..lost a year...but I did show them that they was wrong....by coming in among the top the next year....NEVER give up...use such statement for what they are worth...use them as fuels....that has 10 000 times more value then any READING!!
And now...a big smile...and good luck...and come back after exam and tell you passed with good margin

...(if not....I would be equal proud if I knew I had done my best...then it was just not my trade )
