Week #1
Day 7: Difficult days starting

This is starting difficult to follow as your current R&D research dollar balance and cash balance may have varied a lot depending if you are playing the slot machine or not; and how lucky you were in the workshop.

A fair estimation is you should have about 80M of R&D research dollar and about 200M in cash.

Remember to star your day by spinning wheel, play the slot machine, get the free card wallet, and look for free stuff in the workshop.

Now, the next few days will be more difficult because your cola boost is over.
If you look in the workshop, you may still have a discounted cola (+3.5 boost, for 5 days) at a very low price, such as 4000TC.
This is only available in your first week or so of the game. It was mentioned in day #1 to spare carefully all blue coins and TC.

Check when it expire (tomorrow?), and do your best to cumulate enough TC (slot machine?) to grab this last discounted resource.
This would truly unlock your way to gold star. If you cannot get it, no worries, you should still be able to make it in 8 weeks.
But if you do, your journey will get expedited even more.

For the next couple of days, your sole goal is to unlock all of the 4 levels of "Group #5 - HIGH TECH LAB" (60M each).
This may take up to the next 5 days, depending how your R&D dollar balance is at.

As said, fair assumption is 80M of R&D balance, therefore, for today, start the research of: Group #5 - HIGH TECH LAB (6h, cost 60M).
Once done, max out your R&D budget to 25M/day.

Repeat until:
you reach level 4,
or you ran out of R&D research dollar; which ever come first.

Make sure your R&D budget is always to the roof.

Cola in the Workshop

If you have enough TC to grab the cola, pick it up as soon as your R&D budget is maxed out, or before it expires. Dont let it expire even if your R&D is not completed.

Agenda

Looking at the agenda, there are 33 items (one completed yesterday)
Objective: Own 10 route (already done)
Objective: Own 15 aircraft (if you are lucky, on Monday you should get a free tiny bird on the workshop)
Objective: Perform a group check A on 2 aircraft minimum

Proceed by doing a "GROUP A-CHECK" on at least 2 planes. This is not the same as doing a-check on 2 planes individually.
If unsure, read this section [LINK TO GROUP A-CHECK].

This should cost max $500,000 but will give you 10M. Worth it even if it is not needed at this time.

Summary
- Increased the R&D Budget to at least 25M/day (maybe more, YMMV).
