In 653, you need to remember many things while 510 has a lot of calculations…I find it easier than 653…570 was the easiest.
I would suggest that you take the course 1 or 2 months before the exam date. Read all the code books every day. Concentrate on body of knowledge. Read thoroughly the API 510 code – at least 3x (I read it 6x during exam preparation, in the train, in the loo, in the plane everywhere…why I have to do that? because of “fear of failing”.). That is the most important code for you to study; many questions will come out from that code.
Remember, you can’t rely totally to what you’ve learnt from the course. The key is to read and get familiar with codes & recommended practices. I’m not trying to boast…I got only 19mistakes out of 150questions on my first attempt. I got a perfect score when I took the on-line quiz (6yrs renewal). If a boy who grew up at smokey mountain achieved that goal then no reason why the junkiron can’t. (junk irons from smokey mountain are my precious collections
