Grammar Question/ Overall Question

<p>Hello,
I will be taking the SAT in a week and this weekend will be the last weekend I do any practice questions. I came across a couple of grammar issues that I wanted to address:
1) What tense follows "Until recently", or "By 1976"?
2) What should I do this final week to prepare?
3) What are some hard math questions that tend to appear on the SAT? I'm pretty good with math - usually scoring around 800 - but I've had a couple of hiccups in which I missed a question or two because of time restraints or unusual questions.
4) What's your number one tip for sentence completion in CR? I've tried to memorize as much vocab as possible, but to no avail as I am still hit with foreign vocabulary...
5) What's your number one tip for the actual passages in CR? I got a huge boost when I realized that every answer is and can be supported by lines directly from the text. Now, I'm having trouble doing "main idea" or "tone" questions.
6) When the questions ask you for the best meaning of a word, does that "best meaning" usually exist as part of the word's ordinary definition? </p>

<p>Thank you so much, and good luck to everyone taking the SAT in a week!</p>
