<p>Ok so I have a 64 in my PE class.. and I need atleast a 70 before the semester ends.. We have infinite campus and they calculate grades using weighted averages.</p>

<p><a href="http://s1050.photobucket.com/user/jack_be1/media/IMG_0010_zpsa7be6387.png.html"&gt;http://s1050.photobucket.com/user/jack_be1/media/IMG_0010_zpsa7be6387.png.html&lt;/a&gt;&lt;/p>

<p>Now The assesments have a weight of 60% and the other two have a weight of 20% but they barely move the grade even with all the 90s and 100s</p>

<p>Obviously the assessments are the ones that brought my grades down, We have two more assessments coming up, If i make 100s on both of them will it bring my overall average up past a 70? I did the math and I think i did it wrong but I calculated with two 100s I will be like at 76?</p>

<p>I just need a second opinion, this is my lowest grade and I need this class to graduate. I messed up thinking that this wouldnt affect me and here I am freaking out, If someone can accurately calculate this and help me out I would very much appreciate it. </p>

<p>Why would you post this twice? Why can’t you calculate the number yourself?</p>

<p>It’s not hard to compute. If you get two 100’s in the assessments section, then assuming equal weight, your assessment average goes up to 73.5%, and your grade will be:</p>

<p>grade = 0.2 x 92.22 + 0.6 x 73.5 + 0.2 x 90 = 80.5%</p>

<p>So keep at it and you’ll be fine.</p>
