heyy don't stress out about these scores too much! Be aware that it is more difficult than the real thing, and just study the questions and understand the concepts that arises. Use it as a motivation factor too! How much longer do you have until testing day??
If you look up my previous posts.. i've gotten 13's on the ochem section and 15 on most of the sciences! And this was only 1 week before the exam!! I ended up getting a twenties in the Natural sciences. Just don't look back and keep working hard. I know you can do it!! good luck~
