One way to improve your vocabulary is to read dictionaries. Here's an interesting person who studied the "example sentences" in a dozen dictionaries for thousands of words... and short stories emerged. Here is an example of a story that the author put together using SENTENCES from dictionaries. His skill is finding a connection between two sentences.
Plug in and look for the result that you want to find.
In this example, the formula says "7 cans of dog food in 3 days"
What would make the dog eat 14 cans of dog food? We need ___ days
Ah ha! SIX days.
So if "d" is 3, then we will get "14 cans of food" as a result with the correct formula.
When we put "d=3" WHICH formula gives us "14 cans of food"? That's the aim of this video. ======================================================= Look at the ANSWERS -- don't immediately solve the problem. (1) When there is a fraction, we try to make sure the bottom numbers are the same. (2) When we see ROOTS (radicals), we try to eliminate them from the bottom I made an error in this problem because I immediately tried STRATEGY 2 (change square root of 2 into 2 by multiplying top and bottom by Square root of 2) I should have LOOKED AT THE ANSWERS... We can see that there is a SQUARE ROOT of 5 or 6 in several of the answers. AH HA! I should IGNORE Strategy 2 ("clear the roots from the bottom of the fraction") and focus on STRATEGY 1 ("Make the bottom number the same in the two fractions that we will add")
What happens if I study with a book from 2008? Have the questions changed very much?
REPLY: Yes. The questions that asked for "what is the relation?" are gone. For example Tepid:Boiling is like middle:_______
what's another word for an "extreme"? a) path b) cliff c) peak
Clearly boiling is OVER tepid, so the _____ is OVER the middle. A cliff could be anywhere on the mountain, but the PEAK is clearly over the middle of the mountain.
That sort of question is gone.
Many of the other questions that you will find in a book from 2008 are still relevant. The key to remember is that most of the math is geometry, number sense and algebra, with a few statistics and trigonometry exercises thrown in. Have they changed the strategies? I've heard that it was NOT a good idea to guess the answer.
REPLY: The penalty for wrong answers has been removed.
I've been a test-prep tutor since I scored a perfect 800 on the Math SAT in 1975. The Verbal was 720. Other students wanted to know the tips. It's simple: Keep looking at problems in the workbooks.
1. Look at at least 300 problems. Majortests.com is a start. Number2.com for SAT and ACT.
2. Look at the free examples online
3. Collect the problems that you can't do
4. Find a study buddy.
5. Take the list of problems to your teacher (maybe your teachers will use these problems in class and then you will get the answers free)
6. Send photos of the problems to (954) 646 8246 and eventually the answers will appear on blogs and the YouTube channel
7. Hire a tutor.
Step 2 is perhaps the most time-consuming step because you hae to listen to someone's presentation. Yawn. But you can scroll through and find the method for each problem that the youtube channel gives.
KhanAcademy YouTube channel for SAT is a good source.
