Write shorthand notes during shiur in the following style
Q –
A-
S –
where Q is a question A is answer and S is statement. That will help you follow the Rebbe’s train of thought.
Afterwards, write the shiur over again in complete sentences and copying over the מראה מקומות your Rebbi brought in Shiur.
I very highly recommend the English sefer “Ben Yeshiva” by Rabbi Lopiansky. You should get some good guidance there.
If your goal is to remember your learning 3,5,10 years from now, then memorizing shakla v’tarya is not going to be very helpful. You want to focus on the Maskanos of the sugyos. You can write down the maskanos on index cards. One maskanah per card. If there is a key chakirah in the sugyah that would also be an index card – chakiros can go in a separate compartment. Very important to write on paper, not a computer. Hatzlacha!
