Scared for junior year! Are these courses difficult?

<p>okay, so my junior years starts rather soon and I am SUPER scared. Last year, as a sophomore, I only took (core classes) <em>algebra 2 H, english 2 H, chemistry H, french 3</em>. I only ended up with one B throughout both semesters of my sophomore year. I honestly didn't find the class material as being difficult to understand etc.. but i did have a lot of homework for algebra 2 (almost 2 hours, but that's because I am so meticulous when it comes to math). Also I didn't find the material in chemistry H as being difficult at all, having ended up with over 100% in the class (but i know AP chem requires so much more knowledge)
Now, with junior year coming up, here is what I plan to take... </p>

<ul>
<li>Chemistry 2 AP</li>
<li>Statistics AP</li>
<li>Physics B AP</li>
<li>Precalculus H</li>
<li>English 3 H
(and on top of that I have my sport and ec's)</li>
</ul>

<p>I LOVE science and math, if you couldn't tell.. I honestly don't know what to expect this year. I am just afraid that I wont have enough time to thoroughly do my hw and study for each subject. My friends have said that precalculus H itself is super time consuming and they also have spent nearly 3 hours working on chem AP hw. The teacher for Stat AP is supposed to be really good but my dad believes that i'm going to fail (great confidence booster, i know). And my counselor says that most students start off the year with c's in physics, but we'll see. </p>

<p>Basically, from your past experiences as juniors, I just wanted input from those of you who have taken these classes as to how difficult these classes actually were for you. ( I also have a 3.83 GPA and I'm really worried that after having taken these classes, it would drop drastically) </p>

<p>ALL INPUT IS GREATLY APPRECIATED!</p>

<p>I’m going to be a junior too, but I took precalc last year and it’s not that bad I promise! I don’t usually like math but since this class incorporated so many different things (like geometry and trig) I didn’t mind it at all. Just make sure you learn it before moving on, because my class moved really quickly and if you missed something then you’d be lost. Also make sure you have a good relationship with the teacher (mine let me retake a test that I totally bombed!) Good luck, I’m sure you’ll be fine!</p>
