As others have said, you still have plenty of time to turn it around! Just aim for the best you can possible do for these exams. And regarding pulling up your marks, take summer school to get your average up so you don't get kicked out and you can get into a 2nd year program!. Definitely take Chem 1A03 and 1AA3, and maybe also repeat 1-2 of the courses you did poorly in to get your GPA up!
Point is, don't stress, and do your best on your exams, and take summer school to at least, get chem done!
Good luck!
