Batholiths are large buried igneous (usually granitic or gabbroic) bodies that are roughly dome shaped and have no sensible base. They form when liquid magma works it's way toward the earth's surface, pushing aside surrounding rock, and solidifying before reaching the surface.
Laccoliths are mushroom shaped bodies related to batholiths. They begin forming the same way, but usually are narrower. When a certain set of circumstances occurs the magma of the laccolith spreads out between strata, forming the "mushroom cap" part of the igneous body.
Dikes and sills are igneous bodies that either force their way up through fractures in the crust (dike) or force their way between stratified rock (sill). So, if a narrow igneous body is discovered and it lays parallel to surrounding stratifications in sedimentary rock it is a sill; if it crosses the stratifications it is a dike. Just remember: S ill is the S ame and D ike is D ifferent (from the stratification).

I think of the forms as a text book. If you have a teacher and partners in front of you then learning and training with them will be the best way to practice. However once you are home or have a short term leave where you won’t have an instructor and a partner the forms becomes your best source of learning. Think of the forms also not as a preplanned battle tactics, but as a math text book. You’ll learn 2+3=5, 5+3-2=6, and that 5*2+3-4=9. Will you use these exactly as they are? You’ll add 2 apples and 3 oranges to get 5 fruits, but you won’t have to add 5 apples to 3 oranges then take out 2 apples to get 6 fruits so much. But the idea is to train the most basics and more likely so that when faced with a new situations then you’ll know the principles by heart and come up with brand new solutions to questions you never have been asked.

a batholith is formed just like an igneous rock. it is formed when large amount of magma from the magma chamber finds its way to the earths surface, pushing the surrounding rocks and solidifies on getting to the earths surface.

I think a batholith forms when a large body of magma cools inside the crust.

like theres this huge magma chamber where lava usually petrudes from right and when it colls and hardens we call it a batholith
