OFFICIAL SAT and ACT prep test guides. These things are HUGE and include practice tests. I've already done like two out of three of the practice tests in the ACT book, but I think the SAT book is unmarked in. I can check if you want. Either way, it'll explain why my answers were right or wrong and your child/you can learn from that.
These things are HUGE. Like phone books. I found them pretty helpful. This would be great for parents or kids who want to be prepared. Brand new these were $20 each. You can have them for the cost of shipping! I was going to donate them to a thrift store but I figured someone here would want them.
They helped me get a score of 1830 and 30 respectively I did like the books recommended and re-took the SAT and ACT twice. On the SAT my score stayed the same, on the ACT my score went from a 24 to a 30. In my defense, I was hella nervous and had practically no sleep! I won't say these books were invaluable, but they gave me a real confidence boost that I definitely needed at a stressful time. I can give them both to one person (save some shipping money) or I can give one to someone and another to someone else. If you do want it, post here what you want and them PM me so the next person who wants something will know if it's up for grabs. If no one wants them, they'll go to the thrift store.
