SAT
In simple terms, yes, SAT is a difficult exam. The candidate has to sit for four hours and answer every type of question from the Maths and English sections. While some questions are direct, some are very complex. The Critical Reading Section of SAT is the most challenging one. JEE and SAT are two different exams based on different parameters. The main requirement for SAT exam is having a good hold of English. Though JEE is also sometimes considered easy if the candidate knows the concepts properly, the formulas can make someone go mad. Whereas in SAT the concepts tested are of 10th standard, and the formulas are also given on the question sheet.
