<p>hi.i have registered for math2 but instead i want to give chem.can i do it??should i inform the proctor or just write the code in the answer sheet and do chem??thanks</p>
<p>Got to the collegeboard website. Got to your organiser and click print my ticket. There, under Examinations portion, you can select “change” and you will be given further info. on how to do so.</p>
<p>well it seems that i can not change them…what if i just go there and do the section that i want instead of what i have registered??</p>
