First of all, you should properly go through the detailed feedback report to understand your strong and weak areas.
The report is available after log in, on your scores page. The report will help you understand the areas where you didn't fare well and help you understand how you can improve your employability and AMCAT scores.
If your scores are low in just one module, there are chances that you will get job opportunities depending upon the criteria set by different companies.
If your scores are low in all modules of the AMCAT exam, you should read and understand all the points mentioned in the feedback report.
Post reading the report, we recommend you train yourself using the reading material to prepare yourself better. You may re-attempt AMCAT after 45 days of your latest attempt.
