Omo..........Initially I no want talk anything but I thought say there are fellow aspirants here who did not write the mock exam and who might have concluded their studies or reduced their reading pace thinking that they are FULLY LOADED.....Just like I felt when entering the hall to write the Jamb mock

I started jacking for this JAMB with INTENSE MOMENTUM since November last year till now leaving almost no stone unturned and seriously aiming for at least 380 in the mock.......and I come de score this rubbish........Chai......JAMB.....

Abeg fellow aspirants here!!!........we still have one good week and it is enough for intense revision!!!..........
Jamb no be beans!!!
Jamb no be moi moi !!!
Jamb no be akara!!!

Abegooooo, no say your brain de hot.......Omo brace up and study!!!

I scored 262.

Please I need advice as well from the gurus here who scored higher as to any possible means to manage the remaining one week left to be able to score highest...

I don talk my own finish.

A.

In opposite directions, it'll be B.

Thanks a lot.You just confirmed what I already know..............#CONFUSION CLEARED!

JAMB MOCK PHYSICS.

A---------->90Km/hr
B---------->65Km/hr

If the two bodies A and B are moving in the same direction with velocities 90Km/hr and 65Km/hr respectively,WHAT IS THE RELATIVE VELOCITY BETWEEN THEM??
(A) 25Km/hr
(B) 155Km/hr
(C) 65Km/hr
(D) 90Km/hr

Also,what if they are moving in opposite direction,what will be the relative velocity between them??


Please clear explanatiions will be highly appreciated.

try using this link www.nairaland.com/1180467/enquiries-suggestion-complaint-contact-moderators/3 or try this other one,in education thread that shows the topics under education,looking above you'll find the "mail mod"icon click on it,I've never tried it though.

Alright.....Thanks a lot.

Hardebaryor:
please were you given working sheets and were you allowed to use pen cos I heard some centres did not allow that

They did not give us regulations about that and they did not provide anything but I personally went in with a plain sheet of paper and a pencil..........nobody disturbed me...........maybe because this one is just mock exam.I know they will be very strict during the main exam and like last year,they ought to provide working sheets.

@DRBestJC, Were u allowed to take in biro or pencil or sheet of paper to solve? or were u provided with one?

Rachealoduah:
Thank you very much for the update

Welcome.

Prophylactic:
those past question was it current years or older years please?

I think they are both from past and current years.

For instance,our English Collocation came exactly from 2004 past questions.
Also,I saw questions in physics from 1980s.

Wow. That means the questions
Were completely different for different sets cox none of what you posted
Came out in mine.
The questions are OK(not too OK sha) but the problem I noticed was with the calculator, it only had keys for + - × ÷
I.e. no square root, sin cos etc.
Which is a problem for physics and math questions
BIOLOGY
Which of the
Following fruits
Has Parietal type of placentation?
A. Tomato
B. Coconut
C. Pawpaw
D. Orange

You must be right because I am as well suprised by the question you posted........I did'nt see any question from Placentation in biology.

I have written my mock examination,and I thank God this is just mock...........I go say e dey bittersweet

We came in the morning and were required to pay 700 naira to be permitted to write the exam and I can say that JAMB is just milking nigerian students dry through this exam.We paid 700naira for the mock registration and just a day or two to the mock exam date, they sent us a message requiring us to pay another 700naira to be able to write the mock.........anyway,na naija we dey!

We did thumbprinting and went into the hall with CCTV cameras mounted at strategic positions.At about 9:00AM,we were asked to log in and write.
........and I logged in.....


I checked one of my most dreaded subjects PHYSICS.40 questions were asked and some of the questions I could recall are these: (please let somebody solve and provide their answers.)
1: If y = A sin(750pt - 0.04px),determine the velocity of the wave.

2: P-type semiconductors are produced by doping the target materials with a....
(A) bivalent material
(B) pentavalent
(C) tetravalent material
(D) trivalent material

3:Optical fibre operates on the principle of
(A) diffraction of waves
(B) polarization of waves
(C) total internal reflection
(D) Refraction of waves

For CHEMISTRY....same 40 questions:
1:The action of ethyl chloride on ammonia will produce
(A) amino acid
(B) Primary amines
(C) secondary amines
(D) tertiary amines

2:Calculate the molar mass in g/mol of an alkyne represented by C11H16
(A) 112
(B) 124
(C) 208
(D) 100

3:Which of the allotropes of tin exists at room temperature
(A) monoclinic
(B) Rhombic
(C) grey
(D) white

For ENGLISH,60 questions were asked and about 7 questions from independence....it was ok

For BIOLOGY,40 questions were asked but tough.

MY EXPERIENCE AND ADVICE: I saw many questions lifted exactly from past questions.So it will be wise to study your pastquestions very well.Also TIME IS NO MAN'S FRIEND! Many people could'nt finish when their systems authomatically submitted their works.

I think this is enough to help a fellow aspirant.

In two/three weeks time,IT WILL ALL BE OVER!!!...........and I wish you guys an unprecedented success in your exams.....

SammieJayh:
I hear they are still uploading it tho...or maybe the CBT centre made a mistake while registering you...

Yup...I know a guy who got admitted in 2016 for medicine after being at home for 10 years...that was when I realized I didn't have the passion for medicine...
And yh, I think I chose just the perfect course...

Please.please.please.............Just tell me you are joking!!!.........How can somebody spend ten good years searching for medicine?.......INCREDIBLE!!!....unless he was working and at the same time studying.

afoobabs:
Samson calm down oooo
dont get urself confused

the first question you are arguing on
Choose the correct option.

The government which.........recruiting..........workers suddenly stopped doing so.
(A) are/its
(B) was/its
(C) is/their
(D) were/their.

in this context a plural verb cannot be used with government ooo
although government comprise of a lot of people but the name government has put all of them in a singular entity so government will be treated as a singular
therefore
option B is correct
the government which is recruiting its workers suddenly stopped doing so
another example
1. The presidency has issue a statement on the abduction of school girls in Yobe. presidency in this example does not mean the president alone but himself, his cabinet, his advisers, and every one that works in president office has been put together in singular entity. you will notice that a singular supporting verb (has) is used.

2. Bacelona Fc has lost out in the UEFA champions league. bacelona fc comprise of over 11 players, managers, fans, etc. but they have become a singular entity so a singular verb will be used.

ALso note that government can be pluralise by adding (s) eg.
The governments of the three superpowers are alike in essence
in this case it is plural and a plural verb must follow.

Now
the example you cited in your argument, u also got it wrong

One of the girls who ____ impregnated ____ died
a. was / have
b. were / have
c. was / has
d. were / has

the question is very dicey one to answer
rule: any question that has who which whose to get the subject u will look for the closest noun to the adjective who, which, or whose.

in this case, (girls) is the closest subject/noun to (who). so we go with (were) plural past and the second clause the subject is (one of) so we go with (has) singular

One of the girls who were impregnated has died correct
meaning
a couple of girls were impregnated and one of them has died
cc: iamgoke DrBESTJC

Wait!!!
I'm already sweating trying to understand this topic...

These BLOCK PLURAL GROUPS(such as....The poor, The handicapped, The aged,.... and so on) or UNMARKED PLURALS(such as......police, vermin, folk, youth, cattle....and so on ) are really very confusing.
My textbook(INVISCIBLE TEACHER) says that the two should be treated as plurals and they take plural verbs.

Let's take a critical look at these questions because they look alike...

1: The government which......recruiting........workers suddenly stopped doing so.
(A) are/its
(B) was/its
(C) is/their
(D) were/their

2: The police........happy about the dwindling crime rate.
(A) says they are
(B) say it is
(C) say they are
(D) says it is

3: The helpless............our sympathy.
(A) require
(B) requires
(C) does require
(D) do requires

4: The vermin on his body........hideous.
(A) makes the lunatic look
(B) make the lunatic look
(C) makes the lunatic to look
(D) make the lunatic to look

Anybody that knows the CORRECT ANSWER with the CORRECT EXPLANATION should help out...

afoobabs:
am flattered with those encomiums
pls do not think too highly of me ooo
am also a jambite like u are
we are in this together

Oh my God!......You are a jambite?..........I thought you are even a lecturer...........That means I still have a long way to go!

afoobabs:
@iamgoke and Samsonyte:
i want to believe both of you got it wrong
like samson said a percentage of something should attract a plural verb, while the second clause should also attract a plural verb (were)
note: its (huts plural) not (hut singular) assuming their huts are twenty in number (i believe you know that a place with one or two huts cannot be referred to as a village) half of the huts should be 10 huts so its still plural.
the correct option is A.

DrBESTJC:

This is another JAMB question under this topic.I want to use this one to assess myself and ascertain that I have understood this.....

Sixty percent of the unskilled workers..........yearly by the company.
(A) are retain
(B) is retained
(C) were retained
(D) are retained

My answer is D.

Any countermotion?

ok

IamGoke:
Date will not be communicated to those that did not register right??

Yes....only those who indicated interest for the mock exam during registration will be able to see their date during reprinting.
