Are you tired of Writing Jamb Multiple times without Gaining admission into the University of your choice? Who says you cannot gain admission without jamb? Alevelsprogramme.com has come to Provide a solution to this Menace. Have you heard about the IJMB program? Worry not we will be giving you a full breakdown of what the IJMB program is about.
What is IJMB?
IJMB which stands for Interim Joint Matriculation Board is a PROVEN, APPROVED & CERTIFIED Advanced level programme owned & moderated by Ahmadu Bello University and having coordinating body in various tertiary institutions and different Study Centres Nationwide. IJMB programme runs for a period of one academic session ( 9 - 12 month ) divided in two( 2 ) semesters . It is specifically designed to provide an opportunity for candidates who cannot gain admission to regular degree programmes in Nigerian Universities for one reason or the other , as it requires no JAMB nor post UTME, Also awaiting result candidate can Enroll . The programme is open to all interested candidates nationwide and any course can be offered be it Science, Art or Social Science. Candidates are to be lectured for the stipulated period at your respective Study Center and thereafter sit for the final examination . On successful completion of the programme , successful candidates thereafter utilize their IJMB certificate to secure admission into 200level in any Nigerian tertiary institution by means of Direct Entry . Hence, IJMB is recognised and accepted in more than 80% of Nigeria Universities .
After going through lectures for 9-10 months you are expected to sit for an exam.
Finally, you will be awarded point on how well you have performed after the exams.
The minimum points required to gain admission into any university is 5 points.
The fees for this program ranges between #140,000-#200,000 in our different centres. Registration is #8,000. Call 08148501101 to Register

very easy boss, f=coefficient *reaction 0.02*9.8*15= 2.94N

*Tbose Tutors*

Let it be known that operation total paralysis of TBOSE TUTORS will commence on the 10th of September ( Monday ). Reasons why you need to join
- we are just starting from the scratch and so no one is left behind
- We don't just work, we plan. Each teacher already has questions for each day and so you can be assessed daily
- We shall be inviting guest and students on the last day to advise us on ui admissions and some do's don'ts
- For those who have been receiving our past mock questions on the group, you will sense the orderliness in what we do here.


Save the date
10th of September, we are starting powerfully and no one should miss even a second.

Venue : Abadina pry School 1, UI

As you walk down to Abadina, smile as you see the posters.
If we know it isn't possible, we won't invite you.

Tell me when you're free.. How about next Friday?

You know there won't be Lectures due to postume

No problem bro. I'll be available then.

Pls bosses in the house, help me with this question: A ball is thrown vertically downward with an initial velocity of 14m/s. Calculate the final velocity. g=9.8m/s^2 (a) 36m/s (b) 38m/s (c) 30m/s (d) 40m/s PLS SHOW YOUR WORKINGS!

Someone should pls help me with this question.

abeylysis92:

yeah, you are right t is 1.4 sec v equals u+at which is 14+(9.8*1.4) which gives 27.7m/s will still go for C

But you can't just make assumption like that.

Care must be taken on the value of acceleration g u used. the value of g is 9.8 unless otherwise stated. while i was solving the practice questions yestda i encountered this question. pLS knw the different btw stationary and kinetic friction.
HERE the tfrictional force is the moving force Fm = umg
Fm = moving force, u is coff of friction, mg is normal reaction.
Know u = F/R = ma/mg =mv/t/mg
thus, back to the problem f =umg =0.02*15*9.8

#U1fever.

Eben331:
What about the speed given? Are we not going to use it in the calculation?

no u don't.. The coefficient of ke friction is independent of velocity

Nltaliban:


Old tech lab you mean?


Queenara

Haven't heard of that before.

Eben331:
The question is complete bro.

Yes bro. I think somebody has solved it. It is the inclusion of velocity that confused me

Ok

Is it still possible to obtain UIs post UTME form?

freshsteph:



F-fr=ma

U=a/g

0.02=a/10

a=0.2

F-(0.02×150)=15(0.2)

F=3 +3

F=6N

no option

The answer is 2.94N..

Frictional is equal force required to push it since the block isn't accelerating

F- UR
F - 0.02 x 9.8x 15
F - 2.94N

my daughter got the same answer so since it is not the options, are you supposed to leave it blank is negative marking not in place?

abeylysis92:


yeah, you are right
t is 1.4 sec
v equals u+at which is 14+(9.8*1.4) which gives 27.7m/s
will still go for C

Greetings to you all. At this point, I think y'all should have finished all revisions and should be on endless solving of questions.


Try as much as possible to solve any utme/O'level question you come across

Haven't heard of that before.

What of Old Teach Lab?

Eben331:
Please I want you all to unravel the tricks you learnt in calculating pH, finding sin, cos and tan of any angle, dividing and multiplying standard forms, finding square root of any number, picking correct option when you do not really know the answer and many more, which you used in last year UI Putme. CC: Pes13, Nltaliban, Ajet001, KingOvo, ChiomaMee, Bobola07, Condomsir, samuelizz, IFEOLUWAKRIZ, sirgalahad26, TheHistorian, oldfoolnigger, babablogger and others that I can't remember. Thanks in anticipation.

Not a science student o

This is to emphasise the importance of time management.... Pleaaaaaase practice with a stopwatch as many times as possible before the exam as there is nothing more painful than being unable to solve questions you know due to time constraints
This was my experience last year.....its better to learn from others mistake than one's .....
Also any other advices or exercises recommended by my bosses here should not be underrated or neglected as they might be from past experiences.Thanks

Hello bosses,is it advisable to read foreign(international) textbooks along with nigerian textbooks for jamb & putme. N.B:Physics,biology,chemistry & use of english.
