Dear Dcromagirl; the fear is interfering with your learning. The fear is a major distraction and is hindering you from learning.

I will give you my opinion i hope it is helpful to you.

Buy the paraliminal tapes Personal Genius, Memory Supercharger, and Belief.

Listen to Personal Genius everyday preferably first thing in the morning and listen to Memory Supercharger every evening before retiring. Listen to Belief on the weekends.

If and this is a big if if you know how to photoread photoread your chemistry textbook everyday. Forget about activation.You can learn about activation later. If you know how to do the photofocus and photoread you will have the material from the chemistry textbook operating on 2 levels the conscious level and the other than conscious level. The learning will become easier after multiple passes of photoreading.

You will have the advantage of having the material exposed to the other than conscious mind which can attend to 20,000 things at the same time and the conscious mind which can attend to 6 to 8 things at the same time.

I said forget activation for now because right now is not the right time you have too much stress which hinders learning later in the future you can learn activation on something simple which has no pressure or too much riding on it.

You can benefit from Photoreading only and just use regular study methods but wait one thing i would highly recommend is that you spend 2 or 3 hours learning mindmapping and definitely start using mindmapping with your chemistry class.
