My errors typically come from two area:
1) I read the question, but do no retain elements of the question...or there is to much information for me to process at one time. Because of this, I'll miss something and usually make a simply mistake at the end like solving for the wrong variable.
2) I read the question and can categorize into the correct bucket, but do not see the question "trick" to solving. Hence, I ended up spending to much time and guessing.
Any tips to improve these two weaknesses?
