Hl and Sl: Confused

<p>The Ib subjects for science offered at my school are Chemistry, Physicsm Biology Sl and Hl but I need 3 Hl and Sl am I supposed to take both SL AND HL of these subjects?
I am a tenth grader.</p>

<p>You need to take a total of 6 IB exams, either 3 HL and 3 SL or 4 HL and 2 SL. If your school is offering all 3 of these science courses as HL and SL, this means you can choose whether you want to take the SL class or the HL class. You have to take at least 1 IB science course, but it doesn’t matter to IB whether it’s HL or SL, as long as you get your 3 HLs somewhere. I would choose whether to take SL or HL based on how confident you are in your science skills.</p>
