Chrysanthemums3:
I sent an email to the helpdesk, they asked me to go to the admission office and ask for assistance, and I cannot change back to unilag now

Just try and be patience maybe by the end of this month You should be able to log in. Even me self I have done C.O.I too.

Pes13:
Do you mean this just concluded jamb?

The cutoff for medicine and surgery for utme is just 200.

One of the major criteria for admission is an aggregate score of your( utme and post utme) .

That means any score not lower than 200 in utme and 50% in putme can give you medicine provided your aggregate is up to the cutoff of mbbs in your year of admission seeking.


However, a low utme score gives you a slim chance because you will need a very high putme score.



I hope you understand me.

What of Biochemistry?

Bosses in the house please I need your help ooooo. I have 250 in Jamb, I apply med. and sur. but didn't meet the cut off mark. Please I want to ask which course can I apply for first year? Can I apply med and sur. in my second year? If yes, what are the criteria/requirement? Please I need advise. No insult please just advise. Thanks alot.

The Joint Admission and Matriculation Board (JAMB) have rescheduled the printing of the 2019/2020 Unified Tertiary Matriculation Examination slip to Thursday, April 4.

JAMB’s Head of Media and Publicity, Dr Fabian Benjamin disclosed this in an interview with the News Agency of Nigeria on Tuesday in Abuja.

NAN reports that the printing of the examination slips was initially scheduled to begin on Tuesday, April 2.

Congrat Bro. @ esivue007 I also login this morning, make my payment today and also complete my registration without hitches.

afoobabs Big boss abeg ooo I did C.O.I since 17 of last month and I can't lpgin . Please what can I do??

Eben331 pes13 please who is able to login after C.O.I because I did mine on 17 of this month. And I can't login.

EngrBello:
1.you first find the AREA by multiplying the highest two blocks... ; 40cm and 60cm
40cm/100= 0.4m
60cm/100= 0.6
AREA= 0.6 x 0.4 =0.24m
PRESSURE=FORCE/AREA
where F=mg ; 10 x 9.8 =98
P=98/0.24
= 98/24 x 10^2
=4.068 x 10^2
P= 406.8N/m






2. m=1500. V=20 "U=0.7
F="UR
"U= F/R
F=ma
R=mg
m cancels m.
"U= a/g
a = g x "U. = 10 x 0.7.
a= 7
V^2 = u^2 + 2as
20^2 = 0 + 2x 7 x S
S = 400/14
S=28.57m




height H = 5cm ~ 0.05m
From KE to PE
mgh = 1/2mv^2
m cancels m
2gh = v^2
2 x 10 x 0.05 = v^2
20 x 0.05 = v^2
1.00 = V^2
V=1m/s

thanks alot...

Bosses in the house please i nee help ooo in understanding this questions:
(1) A rectangular concrete block 40cm X 30cm X 60cm of mass 10KG rests on a horizontal flat surface. What is the minimum pressure it can possibly exert on the surface?

(2) In what distance can a 1500KG automobile be stopped if the brake is applied when the speed is 20m/s and the coefficient of sliding friction is 0.7 between the tyres and the ground?

(3) The highest point of a simple pendulum bob is 5cm vertically above the lowest point as it swings to and fro between the two extreme ends. At what velocity does gt swing past the lowest point (equilibrum point) where the string is vertical? (take g = 10m/s2)

(4) A certain radioactive element has a half life of 20 years. How long will it take the activity to become 1/4 of its original?

Thanks bro. Please since you will register tomorrow help me check if Nabteb is on d list. Just to be sure and find an alternative. Thanks

Good day bros. Nabteb exam is not among the list of exam bodies when registering. It only waec, neco and foreign exam bodies that is being found.

Although computer studies wasn't listed as one of the subjects which are not accepted, I still do not have any idea if it will be picked as one of the subjects acceptable for computer science.

They said maths, eng, phy, chem and any other science subjects (excluding geography and agric).

I guess you want to be very sure before proceeding to pay for the screening. I think you should go ahead and pay, and let's see how it goes.

Please bro I made payment yesterday but my transaction have not been processed i don't know what is the problem please help......

But truth to be said, i was there this afternoon. I don't really know which type of prayer whereby you transact business. Why i was saying this is that, immediately the praying program was finished, every group of youths that went there were paid atleast 1000 naira.
If you are lucky to be there, you need to see fustrated youths sitting down there like people that are into dry fasting for 3 days without food or water.

Good Evening Bosses, My Last name wasn't spelt correctly while attempting to confirm payment 'Ayomid for Ayomide' is it still advisable to go on with d payment since all other details are correct

Bros. my advice is that before making any payment, delete the first reference/transcation details and start afresh again.

CondomSir:
Still the same what

Please go to a cafe if you can't find your way around it.

Thanks bro. I have already done that.
