Getting an Entry like questions into multiple database tables

Hi I would like to ask if this can be done in Bubble.

For example I have a 4 database table containing 1000 quiz type questions each in the database, for example lets name it (Table 1, Table 2, Table 3 and Table 4). Is it possible to present it in front end or pull questions in a set of 100 quiz questions for example 30% from Table 1, 20% from table 2 and 50% from Table 4.

You can always use the :until item #X option on your do a search for operator. This will return the first X items from the search done.

So you could set up 4 repeating groups that get the questions from the DB with the corresponding value of X for each
