-exercises: 0
+teaching: 1h30
+exercises: 3
 questions:
 - "What is a jet?"
 - "Are there different types of jets? What is a recluster algorithm?"
+- "Which types of jets do we use in CMS?"
 objectives:
 - "Learn about jets, their properties, types and reclustering algorithms."
 - "Learn about the difference between gen, calo, pfjet."
 keypoints:
 - "Jet is a physical object which represents hadronic showers that interact with our detectors. A jet is usually associated with the physical representation of quark and gluons, but they can be more than that depending of their origin and the algorithm used to define them."
 - "A jet is defined by its reclustering algorithm and their constituents. In current experiments, jets are reclusted using the anti-kt algorithm. Depending on their constituents, in CMS, we called jets reclustered from genparticles as GenJets, from calorimeter clusters as CaloJets, and from particle flow candidates as PFJets."
+- "Jets are stored in the different CMS data tiers (AOD, miniAOD, nanoAOD). The current recommendation in CMS is to use nanoAOD unless other variables are needed."

-exercises: 0
+teaching: 1h30
+exercises: 6
 questions:
 - "What is jet substructure?"
+- "How to distinguished jets originating from W or top quarks?"
 objectives:
-- "Learn how to identify the origin of jets with high pt"
+- "Learn about high pt ak8jets (FatJet)"
+- "Learn about the different substructure variables and taggers"
+- "Learn ways to identify boosted W and top quarks"
 keypoints:
-- "First key point. Brief Answer to questions. (FIXME)"
+- "Jet substructure is the field study the internakl structure of high pt jets, usually clustered with a bigger jet radius (AK8)."
+- "Grooming algorithms like softdrop, and substructure variables like the nsubjettiness ratio help us to identify the origin of these jets."
+- "Over the years more state-of-the-art taggers involving ML have been implemented in CMS. Those help us indentify more effectively boosted jets."
