SAT/PSAT Test Preparation?

Hi and welcome to my blog,
I opened this blog to help anyone who is preparing for his SAT.
I remember myself when I started - I was so lost and in such a panic.
Luckily I got this great SAT guide that helped me a lot . So study hard and good luck!
I am taking the PSAT in 21 days from now. I need some help. I want to score at least a 2000/2400 or 200/240. I am not very good with the Critical Reading portion. Should I read the passages given fully and then answer the questions or should I read the questions first and then skim through the passages?
For the Math portion, I’m not sure what is wrong. Math is my strongest subject. I am a 100 average student in Math. When it comes to PSAT and SAT math questions, im only getting 500s and 600s. I want to try and get the full 800 for the math.
For the Writing section, I am doing decent. I am usually very good with grammar but I still find this hard.
Can anyone give me some tips/help?
I’m reviewing as many psat and sat questions as i can. The critical reading and writing portion annoy me because i am pressed by time.
For Critical Reading, try to skim through the reading passage to get a general idea of the passage, instead of wasting too much time on just reading alone. For the Math portion, think of it more as a logic test, it’s doesn’t actually test your Math knowledge, more of how you can apply formulas and just break the problems down.
Hope this helps, I been studying a lot for the SAT myself, take it next Saturday =).
The best approach to the Reading section is to skim for main points, authors’ opinions, and examples. Mark each in your test booklet, using your own code (underline main points, circle opinions, box examples, etc.).
Look for questions with a line reference first, so that you’ll know just where to look if you don’t know the answer immediately. Then go for the questions that pertain to the selection overall (the "big picture" questions).
In the Writing section, your best approach is to study grammar, not just test questions. The Writing section questions test your knowledge of such things as Subject-Verb Agreement, Pronoun-Antecedent Agreement, Number Agreement, etc. If you don’t know your grammar, you won’t do as well, even if you study lots of sample questions.
If you haven’t already, get a good test prep book from such companies as Kaplan or College Board, and look for the "commonly tested errors" sections.
Hope that helps!
