<p>So I took IB bio last year, and now I'm taking IB chem. Do you think I could refresh myself by studying for bio this year (even though I learned it last year), and then take the Bio-M test at the end of this year? And does anyone know if I can somehow take Bio-M and E combined?</p>
<p>My daughter took it in her third year of ib biology hl senior year.</p>
<p>Then do you think I should wait until I take bio HL in junior and senior year?</p>
<p>You can ask your teacher if they think that all the material for the test has been covered in class. Study from a guide like Barrons and take a practice test to see how you do. Maybe you can make a study group with your friends to go over the material for the test.</p>
<p>My daughter had Biology in 9th, 11th, and 12th grade. (HL)
In junior year she asked her teacher and she was told in our school the molecular part is taught in the senior year curriculum.</p>
