Dexedrine is made up of 1 amphetamine salt which is dextroamphetamine. Adderall is made up of 4 amphetamine salts, 1 of which is dextroamphetamine which makes up 25% of the Adderall pill. Ritalin usually requires a dosage similar to Adderall and twice that of Dexedrine to be effective. Difference in effect: Adderall is prescribed in approximately twice the dosage of Dexedrine. A 10mg pill of Adderall contains 2.5mg of Dexedrine but has similar effect as 5mg of Dexedrine. Due to the 4 different salts and increased dosage needed, Adderall is more likely to give side effects than Dexedrine.

You may have had an experience where you took a test for a class, and the instructor showed you the classâs results afterwards. The results probably mapped out into the infamous âbell-shaped curveâ, with a few people scoring on the low end of the curve, the majority clustering in the middle, and a few people scoring on the high end. What you may not have known is that this is a normal distribution found in norm-referenced testing. Norm-referenced tests (or NRTs) compare an examineeâs performance to that of other examinees. Standardized examinations such as the SAT are norm-referenced tests.
