I understand the aversion to math, but if you can master these few calculations, the math FRQ can actually become 6 easy points and maybe your best FRQ out of the three! You got this.
@@WarlordofWarren Woo-hoo! It's a great way to wrap up question 3 if you're comfortable with math. Just double check that every number has units (both set-up and answer) and you should be set. Doesn't hurt to brush up on NPP, population growth rate, and half-life too, just in case they throw a curveball on the FRQs this year.
Same I'm fail, I'm not memorizing this lol. Too much to remember, but gotta have confidence. Either way I took Apes because I enjoy science. Less about college credits.
Exam is tomorrow. Absolutely terrified and afraid that will not be able to focus. I’ve been listening to these videos and watching a few but I’m still nervous. Hopefully I don’t do terrible though
The ES test this year in asia pacific has just ended, now hope u all passed and get five in the North America's test center. Best wishes to you guys! Thanks to Mr Smedes, you helped me a lot!!!
Mr smedes im gonna get a 5 on this exam with ur help, ill be back whenever we get our grades back or after our ap on thursday. also, shoutout Mrs. Kaidy from McQuaid Jesuit she says she met u once.
Hi Mr. Smedes! Your videos have really helped this year with self studying the course. I was wondering if the exam will give conversion rates or if they will all just have to be memorized? Thank you!!
12.2 cents expressed in dollars is $0.122. You can divide 12.2 cents by 100 to convert it into dollars since there are 100 cents in 1 dollar. I probably should have actually shown this step in my set up, so thanks for asking!
Hey! Could you possibly find a way to insert captions into all the videos in your ultimate APES review packet? It's hard for someone like me, who's fully deaf in their left ear, to hear especially when you're talking very quickly.
Hi Sub Zero, this is a great suggestion! Sorry I didn't think of this accommodation for the Ultimate Review Packet videos. Let me do some research and see if there's an easy way to add this feature on the Ultimate Review Packet website or if I need to have captions added to the video file itself.
@@Jjjj-ft6rw I don't think i did that well but at the time i was struggling with English and my teacher talked fast lol and i didn't really know how to study but as long as you know how to connect all the concepts and support them you should be fine. ;)
so.. i did 80%/100 in my ti-36x pro calculator, and i got .008, and my final answer was .07752 tons of co2 at 6:18 so im wondering if i did something wrong or it was just my calculator 😭
My teacher is giving us FRQ math practice but she never taught us how to do the math and I'm confused on how to do the work. Is this normal or am I just dumb?
I'll try my best! Basically, the amount of Uranium decays to half as much every 704 million years. (ex: if it started as 10 grams, then 704 mil years later there would be 5 grams.) In 2112 million years, 704 mil years has passed three times (because 3 x 704 = 2112). That means Uranium experienced three half lives. So we divide the original amount in half three times.
Think of half-life as the time it takes for something radioactive to lose half of its "stuff." If you have a jar of radioactive jelly beans, after one half-life, half of the jelly beans will have turned into something else. After another half-life, half of what's left will turn, and so on. It's like a continuous process of splitting things in half. Here is a sample problem: A radioactive substance has a half-life of 10 days. If you start with 100 grams of this substance, how much will remain after 20 days? We can start off by taking the number of time passing by and dividing that by half-life, which is 10 days in this case. So 20 days/10 days = 2 half-life periods. 2 half life periods means that the mass of the substance has been halved two times. Therefore, you divide 100 grams by 2 for 2 times. 100/2 = 50 50/2 = 25 Your final answer would be 25g remaining. Is this helpful?
John 3:16 For God so loved the world that he gave his only Son, so that everyone who believes in him might not perish but might have eternal life. Just close your eyes and say “Jesus, I don’t have faith in you, please help me believe” Jesus loves you, turn to Him before it is too late. He loves you so much that He died for you. I’m praying for you❤🙏

yep
i’m wondering if there will be a formula sheet in the test. Or if there will be a conversion section

@@Mr.Smedes Thanks Mr. Smedes😃
Great video
THANK YOU SO MUCH!!!! The APES exam is in 2 days!!!
How'd it go
Rapid studying a couple hours before the exam. Fine with MCQ, potentially cooked on FRQ.
MR SMEDES I THANK YOU FOR EVERYTHING YOU HAVE SHOWN ME
Thanks for your interest in environmental science!
Everybody lock in today
studying the day of the test 🤗
quick question: for the second question, can you just write down the actual number like 7,752,000,000 tons of CO2?
That should work! You can generally use scientific notation, write the whole number out, or write 7.752 billion, as long as you include units.
still don't understand how to calculate the half-life of an isotope.. oh well guessing game will have to be on point during the MC
me studying 10 mins before my test💀

Me too (I'm taking the late test today)
so we’re all here rn huh…

What is the difference between NPP = GPP - R and NPP = GPP - RL ?

9:52 I understand the canceling of the liters, how did you get the 1,000 mL?
1 Liter = 1,000 mL, he introduced the 1,000 mL in order to cancel out the 2,200,000 L if I’m correct since we’re trying to get the weekly revenue.
@@westlipid Great explanation!
For a half life problem on the FRQ , would the AP exam graders be fine with using exponential equations and algebra to solve for the time in years?
yes
will they give us a formula sheet for the dimensional analysis :((....
Ask your teacher if you can put it into your calculator before the exam
Is there an exam review for the units other than the (1-5) unit video
so.. i did 80%/100 in my ti-36x pro calculator, and i got .008, and my final answer was .07752 tons of co2 at 6:18
so im wondering if i did something wrong or it was just my calculator 😭
You calculator probably made a mistake.
@@AurilaqqYoure right
I literally just did 80% divided by a 100
it shouldce just been 80
why is doubling time the rule of 70 and not the rule of ln(2)?
My teacher is giving us FRQ math practice but she never taught us how to do the math and I'm confused on how to do the work. Is this normal or am I just dumb?
Very helpful video, thank you!
math has always been my lowest score in apes tests because I never remember (or care to remember) the formulas…
