Not satisfied with my GPA. is a 4.0 reasonable for junior year?

<p>I had personal problems last semester and got a 3.6 so my cumulative dropped to a 3.78 (unweighted). As much as I regret it, there's no going back and I will be able to raise my cumulative to about 3.82 by the end of second semester of sophomore year. I'd really like to go to Pepperdine or any prestigious UC's but i'm concerned that my GPA will drop junior year since it's very rigorous.
Would a 4.0 be reasonable with my workload next year?
IB Math HL (AP Calc BC equivalent, I self studied Calc AB and feel confident)
IB Bio SL (AP Bio equivalent)
IB English SL(AP Comp/Lang equivalent)

<p>I don’t see why not.
(Although a 4.0 cumulative unweighted would be impossible at this point.)</p>

<p>Seems rather reasonable, I had a harder schedule this year and pulled a 3.9…</p>
