Mcqs and online quiz for preparation:

We have taken all these mcqs from the past 15 years of old papers and we also updating this collection regularly in-order to make it easier for someone to prepare for their job test easily and take good score in the test.

We have divided all these mcqs into their respective subjects so that one can open specific subject and study all mcqs related to that subject only.

Thanks to our Mcqs Quiz :

Our online mcqs test can be taken without the need for login/register into the system. we just made it very simple so that after study and preparation one can take the quiz without any difficult

There is also no limit on how many tests you want to take. Just click here to go the quiz page. select number of mcqs you want to attempt, choose subject that to be included in your quiz and click on start. Now attempt your test and at the end you will see your quiz score and also you will be able to see each of your mcq with correct answer and the answer that you have selected.

Federal Public Service Commission(FPSC):

FPSC exam is an mcqs based exam conducted for posts in federal government sector, Police services, Foreign Services and administrive servies etc. It checks the ability and skills of candidates in specific area. the weightage of post related subject is heigher in it and every post there are compulsory subject's mcqs as well like pak-study,islamiyat,english but it weightage is round 30% while 60 to 70% mcqs will be field specific. Federal Public Service commission posts are announced on first sunday of a month. so you will need to check their website on every first sunday of the month. www.fpsc.gov.pk is the official website where you can also see syllabus for your specific post as well so you will clearly see which subjects are included in your test and then came here to study and practice all those subjects before going to take your real test. Qualification required for most of the FPSC posts are bachelor's degree passed in 2nd division or grade C.

Provencial Public Service Commission:

There are also provincial public service commission tests for hiring beurocrats

Central Superior Services(CSS):

CSS exam is conducted by FPSC, its a very tough and competitive exam. It consists of round 12 total papers having 1200 total marks. There are 20 mcqs in each paper except essay and mathimatics and these mcqs can be studied on mcqpk.com as we have collected all these mcqs from past papers of css and all other papers and books as per relevant syllabus.

National Testing Service(NTS):

Its completely an mcqs based test, mostly there are 100 mcqs of total 100 marks paper. there are 4 to 5 options for each mcq and you have to pick the right option. 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.
