Try either of these:  Ginko Biloba (an herb), Choline (a nutrient), L-Glutamine (an amino acid).\n\nI take Ginko Biloba regularly, and it boosts you alertness and your mental agility.  You can buy it, or any of the others, at a health food store, or even at Walgreens, in the vitamin section.

When I was 15 I went the party-girl route, and I had a lot of fun, but I took it too far and my grades suffered. I ended up having to go good-girl in order to get enough credits to graduate high school. But life isn't black and white, you can party, just do it in moderation. I would suggest staying away from drugs though, because they can have long term effects, especially on your memory (trust me!) :P

Back when I took it, in 1989 or so, I just used the practice test that they give you.  I've used Kaplan for a couple tests since then, and they have a pretty good idea of what to study.

Just observations.  Exercise.  I do not mean lots of exercise.  If you are used to sitting a lot.  Get up and move around.  Do some walking around the house or outside.  This keeps the brain supplied in blood.  A better supply of blood will help.  This may not be your problem,  I cannot say.  Just a suggestion.  (You may be 19 and very active????)

be sure to find a few minutes a day for 'you' time.  get a cup of coffee/tea and a goofy magazine that has nothing to do with what you are studying.  then allow yourself about 15 minutes a day to enjoy these things.  this system helps me deal with work, job and 3 kids, so maybe it will help you!

Concentration Techniques\n\n1. Jot down things that are on your mind before you study, then set this list to the side. Add to it anything that distracts you as you are studying. Take care of the list later.\n\n2. Study at the same time each day. A regular schedule can help you frame this as “study time”.\n\n3. Set a timer for an hour, don't allow yourself to stop studying until it goes off.\n\n4. Take breaks. A three minute break for every 30 minutes of study is a good guideline. Take a longer break after 90 minutes.\n\n5. Set goals for your session that are realistic (number of problems to solve, pages to read, etc.) When you have met one of your study goals, reward yourself with a short break. Then, return to your study area.\n\n6. Study in an area away from distractions such as a library, study lounge, or an empty classroom.\n\n7. Make sure you have everything that you need before you begin.\n\n8. Make sure your environment is conducive to studying, no TV, no telephone, no roommate, no boyfriend/girlfriend.\n\n9. Make studying an active process; take notes and make review sheets. Intersperse different kinds of study into one session, e.g. reading, writing, taking notes, memorizing, etc.\n\n10. Identify how what you are studying is relevant to your life. Draw connections between things you already know.\n\n11. Insure that you are sleeping enough, eating well, and getting regular exercise. Your mind will be more alert, and you will be less likely to fall asleep or daydream.\n\nGOOD LUCK !!!

Rote memorization, with flashcards possibly, is the only way I can think of. Like the other poster said, look for carbonyls, alcohols, alkenes, and amino peaks (a weak, wide peak at about ... 3200 or so)

Contact your doctor about it. Depending on your doctor you may need proof that you have ADHD. If that is the case you will need to contact who ever first diagnosed you with ADHD and/ or who first prescribed it for you.\nAlso, just because the amount you took as a kid worked, does not mean it will work the same as an adult.\nI was diagnosed at 16 took ritalin until I was 21 and stopped. I too recently realized that being on it again would benefit me greatly. I spoke to my doctor and he prescribed me some. It was that simple.\nBut it may not be that simple for you. And the ONLY legal way to obtain a prescritption medication, particularly a controlled one like ritalin is with a dr. prescription. It may be annoying but it is the safer, legal way to go about. There are more options availble out now and you may find one that works better.\nGood luck

Try a pharmaceutical chemist. They may be able to obtain a small quantity for you.

Start playing a video game that you enjoy. It will help improve your concentration.

I actually learned a lot from DARE. But I also was taught about it in the mid 80s. But I have stayed away from drugs. And I was almosted kid napped but I remembered the training I learned from the program and I did what I was taught. I don't know how the program is set up now though, but in the 80s I think that it was a good program and taught a lot
