Many students believe the answer to a higher DAT score is taking more and more practice tests. In reality, improvement comes from identifying weaknesses, learning the underlying concepts, and understanding why mistakes happen. A strong foundation leads to better long-term results than simply...

Many DAT students confuse nuclear charge with ionic charge. An atom can gain or lose electrons, but does that change the number of protons in the nucleus? Take a look at the question before viewing the answer and see what you get. This is a simple concept, but it appears frequently in DAT...

This is a concept that shows up often in DAT General Chemistry and catches a lot of students. The answer is on Slide 2, but before you look, ask yourself: Why are some transition metal compounds colored while others are white? What answer did you get? Students often ask which DAT study...

Here is a DAT-style Organic Chemistry question from Dr. Romano. Adipic acid is prepared by the partial oxidation of cyclohexane. A sample of 25.0 g cyclohexane reacts with excess oxygen to produce 33.5 g adipic acid. Can you determine the percent yield? Before looking at the answer slide, try...

The Golgi apparatus is responsible for protein processing, targeting, glycosylation, and post-translational modification — but not protein degradation. Protein degradation is primarily carried out by lysosomes and proteasomes. Many students confuse the Golgi apparatus with lysosomes because...

This type of dosage and unit conversion problem combines proportions, dimensional analysis, and metric conversions — all common quantitative reasoning skills tested on the DAT and OAT. Focus on setting up units correctly step-by-step rather than trying to do the problem mentally. DAT Destroyer...

Students often memorize terms like Okazaki fragments without understanding why they form. Focus on replication direction and DNA polymerase activity at the replication fork. The lagging strand is synthesized discontinuously, so multiple RNA primers are required. DAT Destroyer DAT Destroyer...

Dr. Romano’s Dynamite Biology Review is now complete. These biology notes are the result of more than 35 years of Biology and Biochemistry teaching experience and have been made specifically for the DAT and OAT. The goal was to eliminate wasted study time and help students focus on the...
