Yes, you can submit an application first and send in the result of the mathematics exam later. The result of the mathematics exam must be received by the RSM Admissions Office no later than 15 March so plan your exam date accordingly. Also, keep in mind that it may take up to 8 working days to receive your results for the OMPT exam. For the other exams (e.g. Boswell, CCVX), the processing time is longer. It is therefore your own responsibility to schedule the exam on time.
A sufficient result of a Mathematics test does not guarantee a spot in the programme. It is simply a tool to make up for any deficiencies in your Mathematics level or grades.
Do not wait for RSM to inform you that you need to take a mathematics exam. You can see if you meet our mathematics requirement for your diploma type by reading the requirements on the RSM website.
