revaluation gain

I understand that this question may not necessarily relate to this forum, but I really need your explanations as they help me best.

“The $1.2 million balance on the revaluation reserve is transferred from the revaluation reserve to another reserve account (probably retained earnings) but is not reported through the statement of profit or loss for the year.” (Kaplan, FR kit – answer to question 3)

$1.2m is the amount of revaluation gain of the property, after my subtracting the Carrying amount with the Revalued amount (both figures are on the day of revaluation).

What i do not get here, is why this transfer of revaluation reserve (on the Statement of financial position) to Retained earnings (also on the SOFP) is not reported through the Statement of P/L. Could you give me some reasons/journal entries?

Also, other than Retained earnings account, which “reserve” accounts would the balance on the revaluation reserve be transferred to? And what is it for?

Besides, I am also confused when it comes to the answers which include such abbreviations as b/f, c/f, balance figure, or b/d and c/d. It really bugs me as I only understand these by imagining a T-account structure of that account. But, most of the time I have to read the calculations in the answer to “guess” the structure of the T-account, then figure out which items are in the Debit/Credit side, and what’s the bal fig etc. Then, finally get to the same calculations as shown in the Answer.

How can I do the calculations without a T-account? Or, is there a list of full T-accounts I didn’t know about?

Do you recommend any resources which could help me right away fill this knowledge gap of mine?

Many thanks.
