Please, correct my essay.

The speakers cannot make their groups for the science project because groups should be made up of three people. The woman suggests that they ask the lecturer to let them make a group of four people. Another option is that the man joins up woman’s group. I think that they should ask the lecturer to let them make a group of four people. The reason is that as the woman said, their class is unevenly numbered, so they cannot help making a group of four people. If they ask the lecturer if it is wrong with the idea, they should make a group of four.
