I am an hnd holder in science laboratory technology (microbiology option) and will like to still study medicine......i am really confused on how to go about it.....i will appreciate ur criticism coupled with useful advice.......tnx

What's the confusion? You're a scientist already, all you are doing is going for another science course. So go pick up a JAMB form and start from 100level. Because if you're thinking of some kind of conversation route into 200 or 300level, that is almost impossible in Nigeria.

Or is your predicament financial?

Begin now to study hard for the next jamb. Some schools regard the HND as a first degree and so may grant you direct entry. Get conversant with the next jamb brochure and school requirements.
All the best.

Hmmm

I think I am determined to go to
any extent just to study medicine,even though I have hnd in microbiology.......if u have any helpful advice pls relate with me......

Bro don't b discouraged you can still opt in for ya medicine .just read for your jamb and pass it thou jamb is becoming rubbish o
