Pls I dont knw which state university to choose, either EKSU or OOU. Which one out of the two accept 2nd choice for medicine and surgery? I think I should choose medical laboratory science or pharmacy in order to boost my chance of getting admitted since they are not as competitive as medicine or what do u think? Which of the two universities as stated above is accredited, has good medical school, affordable school fees? Pls I am really confused right now and I have been thinking abt these things day and night. Thanks in anticipation.

Hello Racheal, delsu MBBS quota is about 60. Their aggregate is usually (Jamb/ + (PUTME/2). Their post utme us usually /100, so just aim scoring as high as possible. For a good jamb score, read your textbooks back to back, word for word, phrase for phrase, solve all excersises, answer past questions from 1978 till date. Note DELSU post utme has lots of maths and English questions... You may not be allowed to use a calculator

pls did delsu accept 2nd choice last yr?

I understand u. You hav to study a course u av passion in and desire for, and nt because u are desperate for admission or because d course is lucrative. You just dont hav to give up on ur dream course. Besides, u av to make changes on those areas u made mistake last yr and pray to God.

oga Pes13
pls which course would you recommend for an Average student(65%)to study? my preference are
Medical laboratory science
Dentistry
Agricultural economics.
I scored 30* in jamb,and am very good in Biology,good in chemistry, and fair in physics.
I like health related course,but one that can put food on one's table in Nigeria's economy.
but I learnt UI has increased its tuition fee of medical students, which is giving me second thought of medical school (college of medicine as a whole)
that's why I chosed Agric economics.but I want to change to any of the above.
advice also needed from oda bosses and readers,I really need advice before i go for change of course on Monday.

Vf=√2 *1*10.. Vf=4.47.....1/2m(vi^2-vf^2)....
0.5 * 1(100-22)..=0.5 * 1 * 78...=39J...another method...mghinitiall=mghfinal +energy lost...energy lost = mghinitial - mghfinal...
Mg(hinitial- hfinal)...
1 * 10(5-1)...=10 *4= 40J...got 39j base or rounding up in first method...I use g= 10 for convenience...should be= 9.81

you are right bro but u didn't use the parameter given, u were given 9.8m/s2 and nt 10m/s2. You av to be conscious of instruction. UI won't give their parameters in whole number.
