Tips for amazon first online assessment.

A month ago I applied for a job with the Amazon Student programs as a software engineer, and just received an email saying I have 7 days to complete their first online assessment (I have 1 attempt and 1.5 hours to complete.). This first part consists of “code debugging and logic/problem assessment which is multiple choice. For the debugging section I can use Java, C, or C++. I feel most comfortable in C as that is what my last 2 classes were in, but I know C can be more difficult than Java which I do have experience with just not as recent. I am pretty nervous for this as I do not know what to expect and I feel that C debugging may be more difficult than java overall. I would really appreciate some advice on what to expect and also if you guys think I should brush up on my java and take it in that or go take it in C. Any advice is much appreciated.
