AWS Certified Solutions Architect-Professional SAP-C01 New Feb 2019 Version Exam Notes
# AWS Certified Solutions Architect-Professional SAP-C01 New Feb 2019 Version Exam
## Final Tips:
1. Don't cram! If you are not ready to take the SAP-C01 exam, then just re-schedule it to a later date. Haste makes waste!
2. Read the question first and then look at the options. Most of the time, you will notice that there are two seemingly similar options which only differs in one or several keywords. This will help you eliminate the wrong options much easier.
3. Take the free AWS Exam Readiness course in https://aws.training and other free courses/videos there.
## Exam Notes:
- The new exam has *75* questions that you have to finish within *3* hours (180 minutes) with a minimum passing score of 750 out of 1000. The official AWS exam page says the exam is 170 minutes, but that is actually incorrect. I took the exam and it is 180 minutes and not 170 minutes.

In the array, element 1 occurs once, 2 twice, 3 three times, 4 fours times, and 5 five times, making element 5 the most common element in the list and 4th the second most common element,
