Taking exam is no guarantee of passing when you get older,..... afraid to fail and get criticise...then there is this long waiting of result that cause anxiety which is hazardous for those having weak heart. The good thing is you will get much closer to God for praying always to pass.
There is this exam exemption if able to meet a requirement of 80hrs PDHs during the nine year certification period. Twenty (20) of the PDHs must be earned in the final three year period. Why don't you try and dig your records at home. You may request for course certificates of attendance from those society / institution / company that you participated in the past 9years.
I did not take the test to renew my CWI & SCWI after 9 years, what I did is to submit the course certificates, seminars, talks I attended related to Inspection, Testing, Safety & Audit courses for past 9years. No questions at all, the first indication to know if your renewal application is approved is to wait for your credit card statement.
Wish you Luck!
