Hi.... Good to know ... You aspire to be medical professional. Certainly revising and hard work will pay off rather any medicine unless you have any health issue or behaviour problems as such .. ADHD(attention deficit hyperactivity disorder) etc.

Hello freind.. Memory  is just like muscle. Use it or loose it. Try to concentrate on basics. Understand the concept. Revise it repeatedly. That the key of success.

Hi ... infact there are some technique which help you to a large extent . 1. Go for a walk . It has proven that walking or exercise can boost concentration and memory and brain power 2.what you have learnt try teaching someone else or an imaginary person ...the material stays in your memory for a longer period of time this way 3. use diagrams ...flowcharts while studying.. visual memory is very useful in retaining information. 4. Reading your materials...you will be surprised to know that when you hear your own voice you can retain information faster.. 5. highlight important points... 6 make a summary after every topic.. if this is a kind of information you are looking for you can contact me or any career counsellor to be specific... otherwise if you are looking for any medication to boost memory i m sure some of the doctors here  you will guide you
