MEEEEE
This man just covered more in more detail than my teacher did in 2 weeks in 30 minutes
That’s wut I m saying I m tellin u this dude is built different at this point why should I even have a teacher lol
This man single-handedly improved our test scores by at least a full 1 point outta 5.
Just studied for my whole test in 34 minutes. Thanks!

@@omaressam3793 guess we'll never know
dude just so u know u r the one and only reason im passing this ap exam
watching this the night before my ap exam thank you
Really hoping this helps me with my test on Tuesday!! One of the few review channels I can actually pay attention to
Just wanted to thank you for the great review, but also wanted to accentuate one point. I think you were joking at this point during the video talking about dinosaur and human superiority but for any confused viewers, the phylogenetic tree is not a ladder but rather a lineage, meaning organisms evolved at more recent times are not necessarily “better” than others but rather better suited for their environmental conditions (selective pressures) during that time. Other than that this is a great video, you never cease to amaze!
I have a test over half of this unit this week, this came just in time!
How'd it go I have mine tomorrow? If you remember.
@@haveaniceday3128 I forgot, but even though AP Bio was my hardest class last year, I still managed to get a 5 on the AP exam.
underrated tysm, like your humor
You’re a god amongst men
If there's a question about allopatric speciation on the AP test tomorrow and I get it right, all credit goes to you my friend
First video of yours that i have watched but i guarantee it wont be the last one, definitely going to binge all of these before my exam
i watch your reveiws before every bio test that i take and they genuinley help me tremendously! Thank you for all that you do!!!
Crazy how I actually learned this but and I can’t learn what my teachers are teaching because she talks fast and just doesn’t give good examples sometimes and sometimes mess up her words but this guy literally made me laugh and learn that the same time 🙌🏽🙌🏽
hi, ive been struggling w/ hw equilibrium and you literally explained it in the best way possible. thank you!
You the goat my man, I don’t think you get as much credit as you deserve. If I make a 5 on my exam I’m 100% owing it to you 🐐
I have a test over the microevolution portion of this unit tomorrow. Thank you so much!
I've got my test tomorrow and I think that this is going to help me get my 'A'! I did all of the other stuff I've done to study so far (I make quizlets and my own study guides on a whiteboard), but did not feel prepared enough this time for some reason but I hope this tips the scales.
yo your channel is such a great resource! super underrated frfr
Do i get extra credit if i perform apoptosis during the exam?
Yessss I will be back in about 3 weeks to study for this test. Thank yoouuuu!
Currently praying that I pass the AP Bio exam and living off your videos, thank you!
