Reasoning my nemesis

Guys I need your help in reasoning section in bank PO exams In the mocks I am not able to cross 20-22 questions This section alone has destroyed so many exams of mine. From SBI PO to sbi clerk any exam level and I can't solve more than 22-23 questions in reasoning. And I feel frustrated and demotivated when I see people doing 25-30 questions in mocks.

I do the miscellaneous questions first and then the puzzles but sometime I get stuck in puzzles or not able to solve them since only1-2 minutes are remaining. I am not able to solve any puzzle in 1 possiblity. It always takes 2-3 cases. My average time to solve puzzles is 4 mins.

Please tell what should I do to improve my attempts? Should I do the puzzles first and then miscellaneous? But then this strategy may backfire in tough shifts.

Please help me guys how do I improve my attempts??What am I missing? I am practicing and solving mocks but no improvement.
