I just finished SIM 2. I had 46 questions in total. There were about 6-8 math questions. They are long questions and misleading. Be careful when reading. I made 7 mistakes in the exam which are about custom clauses. I can say you should expect 15-18 questions on custom clauses/conditions to satisfy your buyer client and some questions on your seller clients. There were some ESA questions here and there. Be careful about the wording, the subject property and contaminated property. It could be adjacent building that is contaminated, not the one you are interested in. Good Luck all.
