The material in class can be difficult but professor Lakshmi is super helpful and loves to help and answer questions. Pay attention to the examples he does in class and read the textbook to be fully prepared for exams. The exam questions are usually directly from homework problems with a few numbers changed, so making sure to know the process for the type of problems you are doing will serve you well. The homeworks can be challenging so go to office hours for help, examples in class do not always give enough info to complete the homework problems.
