I'm not sure about the paper the questions were okay but I know I did not do the best I could have done recently for exams I have been feeling bad about them in the exams I do not put my all at all I just sit there Ive been getting a* in scienes but these exams I don't know what's wrong with me I just have this feeling which makes me feel like I know nothing in the exam and I just sit there its really annoying and its making it make stupid mistakes and losing many marks can someone help me


Oh my god! It feels like u just explained my current situation. Its all even more frustrating because the exams arent too hard and everyone's nailing them and I'm just sitting here like meh

The umbilical cord contains embryonic stem cells which are more useful. Also it isn't harmful to the embryo as it is taken from the umbilical cord so doesn't destroy the embryo. :smile:

Yea you are right, we really should ! I just dont know how , my mocks were so much better than my actual exams. I am overcomplicating easy questions and getting them wrong, and the ones I should have thought about I didnt. Most of the things I got wrong, i did know and thts just devastating :frown:

Percentage I got 0.09 and the ratio 1:639 (but a lot of people put 1:640)

How did you get 0.09? I didn't simplify my ratio but I got that.

Looking at what answers others got i think i have done very badly on this test xD. I wasn't with it either. I hope that i can get at least get an A and then pull it up to an A* on the other two tests :frown:

Definitely how I'm feeling too, I feel as if I'll miss out on my target grades because I'm just not motivated at all
Fml for the stem cell question I put the embryonic stem cell because it can be used to treat a wider range of diseases🙃

for the umbical chord and adult stem call what did everyone write!
I did adult stem cell is that right? I spoke about the ethical issues about the stem cell from umbilical chord?


I put umbilical cord because that contains embryonic stem cells which can turn into any type of cell, whereas with bone marrow you're limited to blood cells
