Hello, I am a chemical engineering student. I have performed as a freelancer and helped a chemistry student with his assignment before on contract. I helped him with 6 assignments within 4 months. I have checked all your documents and they are really related to my expertise. If you hire me, I will not disappoint you. I am punctual and hardworking, I can keep up with the deadline. If you are interested, I can inbox you the sample. This is my new account on freelancer, because the previous account got deleted because of some technical issues. Thank you.
