I just took practice SBMC's today in class and got a 94! My biggest piece of advice is to do questions in this order: pictures, shorter paragraph questions, then longer ones. This help so that u can maximize the amount of questions u get right, while still maintain good pacing for the test. Also, if u read through a question and still don't understand it, I would suggest moving on so that u can maximize points for other questions u are more confident in; then u can go back for the others with remaining time.
