<p>“learning science in general”
-I would say from my experience, learning of the Gen. Chem. / Physics and Orgo / Bio would require completely different abilities. There are lucky people (like my D.) who possess both. Not me, I can easily “figure out” math based Chem / Physics. forget Orgo / Bio.
For Step 1, D. had a high stack of books, I have no idea what and how she was using each of them. BTW. she has already sould some of her Step 1, including un-used portion of on-line help and bought one for Step 2. Time flies…</p>
