I just read last year's Bio Competition and I feel pretty crushed. My chances of doing well are pretty slim now. The questions are all definitely not really meant for grade 11, but if you still do very good as a grade 11 you are deserving of a scholarship.

There are a ton of questions on biological diversity and genetics that suck, like:

23. What DNA sequence information is NOT present in a sequence of complementary DNA (cDNA)?
i. Introns
ii. Exons
iii. 3' untranslated region
iv. Promoter

a. i and ii
b. i and iv
c. ii and iv
d. iii only
e. iv only

The answer is B =\
