unable to use known concept to apply to challenging problems

[nicolec646]

Dear instructors,

Please kindly give me some advice:
I scored 48 during my first test. Since then, I have practiced over 1000 math problems from OG, OV, and other sources, and have practiced over 30+ exams. I've also made correction and reviewed concepts. I recently took another test in Nov....Tragically, I still got 48!

I had some timing issue for the last 10 questions. No matter how many problems I practice, there are still some that I have absolutely no idea how to approach them.

How can I apply my knowledge to challenging problems? Is there a SOP?
Besides practicing my pace, what else can I do to improve my math score to 51 ?
How many problems should I practice per day?


Greatly appreciate you help!
