There are two types of tests one is Nat (its of students taking admission in college/university) and the other on is GAT which is for postgrade admissions. NTS is the first mcqs based assesment organization that started in 2006. The chances of cheating in this test were very low because they give different type of question paper to each individual that sets closer to eachother in the test hall, But previously there were some leaks of this test on social media before paper time and that's why the paper got canceled due to this reason. Nowadays several other alternatives to NTS also exists like Pakistan testing service (pts), Educational testing service(ets) and Allied Testing Service(ats)

MPT (mcqs base preliminary test):

This is an mcqs test which is mandatory before qualifying for CSS exam. The candidate must pass this test before appearing in the real CSS exam. It all mcqs based test. It consists of total 200 mcqs from subjects like current affairs, pakistan study, islamic studies, everyday science, urdu, english grammer and vocabulary etc. You should prepare your self for this exam exactly like you are preparing for css, although its not the real CSS but later you will be giving CSS exam as well after passing this one. Here on mcqpk.com lots of mcqs are available for all these subjects and we have taken them from past papers and relevant subjects in order to make preparation easy for someone. you also can take the test here for free once you study so that you see how much prepare you are. The age limit for this exame is from 21 to 30 years. Previously round 13,008 candidates appear in css exam in which only 398 passed the real CSS exam and this makes a percentage of round 3.06% so normally every year very few people appear in this exam and within these very very small number of people clear this exam.
