When you are in doubt, ask for a second opinion.
Science can be tricky and there are multiple methods that you can use to solve a problem. This means that there are many possibilities for you to make mistakes. When you are not sure if your assignment is correct, it’s better to ask for feedback from a colleague or professor. He will be able to notice the errors that you missed and he will help you correct them.
Use the Internet to get new ideas
And by this, I don’t mean that you have to read other assignments all day long. There are many forums where students discuss about various exercises and formulas, and you can join them easily. When you assignment proves to be more difficult than you can handle, go on the forum and ask help from the users. They will give you new ideas that you can use for your project and advice that you can follow in the future.
Don’t try to invent anything new.
If you are passionate about this subject, you dream about being a great scientist. While this can happen after a few years, now you have to focus on your grades. Make sure that you follow the requirements of your professor in perfect way, and after that you can work on something extra. Besides, it takes years to complete an extraordinary project, so there is no point to dedicate your efforts to this while you are just a student.
