I can sympathise. When doing the groundschool at Coventry for a Met exam I approached one of the instructors and said,
'I'm happy with every other subject, but I've got a serious problem with Met.'
"What's your problem?' He replied.
"I don't understand any of it." I answered.
"Hot things go up. Cold things go down. Now you understand all of it." He said with a smile.
His point was genuine though. He explained that it is too easy to get buried in detail and lose the big picture in Met.
Good luck!
