October 25, 2008 ACT Discussion- Science

Test Preparation ACT Preparation
101

<p>anyone else currently enrolled in AP Bio right now and when u saw the first graph problem about peapods genotype/phenotype you pumped your fist in excitement. i just had a test on it last friday, all the material was fresh in my mind and interpreting it was super easy, unless i made some careless mistake. </p>

<p>but overall i think it was pretty good, first time i ever took the ACTs let alone had any idea what was going to be on science.</p>

<p>for the last passge where there were 3 graphs about magnetism and without, there was a question about one of the first two graphs and chainging it into PO vs. Time or something like that. Did u get a graph that was like a radioactive day graph, because the metal oxide was a reactant and as the reaction was proceeding you would get less quantity of it?</p>

<p>Yeah.</p>

103

<p>Lol, I took AP Chem (5), bio (5 and 790), and currently in AP Physics, but I still thought that was really hard. This is sad :(</p>

104

<p>lol PkW, i took chem ap (5, on a makeup test too! lol), and am currently enrolled in biology and physics AP. idk, the physics passage about pendulums and the one about calcium and stuff (last passage) were iffy.</p>

105

<p>Nothing that was on it you couldn't have figured out with enough time to actualy think about it even if you never took those classes. Its just they don't give you enough time to think about it in depth enough sadly :(</p>

106

<p>Does any1 remember the passage about the magnets and the pure metal? The last question of that one asked for the metal oxide percentage. Was it the reverse of the pure metal concentration graphs? A and B were reverses but which one was it? in graph A the the curve with the magnet(solid line) decreased slower, while in B the curve with the magnet(solid line) dropped faster. I chose B</p>

<p>curve w/o magnet was dashed</p>

107

<p>yea it was the reverses, like a radioactive decay, i don't recall which graph was the one i selected though.</p>

108

<p>im pretty sure the dashed and bold line were switched and it was a reflection</p>

109

<p>worst section for sure T___T</p>

110

<p>so did the bold line decrease faster or slower than the dashed line?</p>

<p>in the original graph, the bold line increased faster than the dashed line</p>

111

<p>im pretty sure the dashed and bold line were switched and it was a reflection</p>

<p>You would be correct sir.</p>

<p>ma'am* lol</p>

113

<p>What's the usual curve for the science section? I wouldn't be surprised if I missed up to 20 on this section...</p>

114

<p>I've heard that just one wrong can bring you down to 34/35 but I'm not sure. Today was my first time taking it.</p>

115

<p>Ok... I need to go on a little rant.</p>

<p>So I actually completed like... 1/3 of the science portion. I knew science was my weakest portion, but really, I had to bubble in B/G for about half of the answers because I was so behind. Gotta work on that speed!</p>

<p>Had NO trouble with the other sections (probably 32-34) but this science score will probably be like a 25. ARGHH</p>

<p>THANK GOD YOU CAN CHOOSE WHICH SCORES YOU SEND for the ACT. I'll take it again and hopefully do better on science...</p>

116

<p>wait wouldnt the graph of pure metal be identical to oxidized metal because as more oxidized metal is produced so is more pure metal...</p>

117

<p>No. The reaction was oxidized metal being reduced to make the pure metal.</p>

118

<p>haha dang. yeah i read it wrong. oops</p>

119

<p>So what was the answer to the chemical equation with NO O2 and NO2? I had no idea.</p>

120

<p>it was 2NO↓2+O↓2=2NO↓2.</p>
